For any software development lifecycle to be effective, complete and accurate information is a very essential element. These two elements are what enable your test teams to work together cohesively in a systematic manner.
This, in turn, ensures that your end product matches the expectations of your customers as well as your business in general. The goal of a test design technique is the testing of features and functionalities using effective test case scenarios.
The process of analyzing your organizations requirements from a business point of view goes hand in hand with proper testing. Determining the accuracy of completed information can be done using ambiguity testing techniques, which happens to be one of the top testing design techniques.
Basically, a test design technique's main goal is to determine a proper series of tests from a pool of all the possible tests for a particular system. There are numerous types of software testing techniques.
Each one of them has their own weaknesses and strengths. Each technique has it's own way of identifying different types of defects.
So what are the Test Design Techniques covered in the ISTQB exam? Coincidentally, the two main categories covered by the ISTQB exam are the same categories we're going to cover in this article herein below:
Dynamic techniques are divided into another three major categories. These are:-
This technique is also referred to as specification based or behavioural techniques. This technique uses the software's external descriptions such as customer requirements, design, technical specifications and so on.
In this technique, when the tester doesn't fully understand the software's code or its internal structure they can perform tests using methods such as Boundary Value Analysis (input values are tested at the boundaries), Decision Table Testing, State Transition Testing, Equivalence Class Partitioning and Use Case Testing.
This type of technique is based on the software code as well as the program's internal structure, testing each of them individually, one after the other. In this type of technique, testers and developers usually have a proper understanding of the internal structure and the program's software code.
This test-design technique doesn't concentrate on external or internal structures. The testing is based on experience and the following test methods are usually adopted when it comes to scenarios such as; Fault attack (here errors are anticipated by testers) and Exploratory Testing (application testing without test case documentation).
This technique is all about manually testing your software product. This process is usually started in the early stages of the software development process. This means that it is most likely going to happen during the verification stage.
The fact that the testing is done without the need to execute the program means that you will not have any need for a computer. These testing techniques can be applied to several forms of documents. These include design documents, source code etc.
In the input values' extreme ends is where errors, for the most part , are observed. These extreme values like lower/upper or start/end values are known as Boundary Values.
Boundary Value Analysis is the analysing of these Boundary Values. It's sometimes also referred to as Range Checking. Boundary Value Analysis is based on black box testing technique principles and it's main objectives are to locate errors at input domain boundaries rather than finding the errors at the input's center.
Boundary value analysis and Equivalence partitioning are kind of intertwined and can both be used together at different levels of testing. Test cases are derived for the equivalence classes edges.
Each individual boundary contains invalid boundary values as well as valid boundary values. Normally, each boundary will contribute one test case each. Finding defects using this technique can be quite effective and it has the capability of functioning at most levels.
Your previous experiences or needs are what will determine your choice from the multiple test case applicable from invalid and valid input domains, however, you must remember that you will still be required, from each input domain, to select one test case.
This testing technique is quick, easy and a fantastic way to catch input anomalies that may play a major role in interrupting the programs functionality. So, to cut short testing procedures and save time, experts delivering quality management services as well as software testing heavily rely on this method.
Equivalence Partitioning is basically selecting single input values from every range from a range of values that is made up of divided test input data. It also happens to be a black box based testing technique and its main objective is the calculation of the effectiveness of certain test cases.
This technique also has the ability to function at all testing levels from integration, unit, system testing etc.
In this technique, input is split into several different classes. The equivalence class input criteria represented by each individual class. One input is then chosen from each class.
What this method does is it reduces the number of test cases from an infinite number to a finite one. All this while still securing the effectiveness of each selected test case that has been assigned to monitor all the possible scenarios.
A basic Equivalence Partitioning concept is if a range from one to hundred is being accepted by one application, then those inputs can be divided into classes using Equivalence Partitioning principles. Example, design, invalid as well as valid input all get each class to provide them with one test case each.
One of the most vital components in the testing phase is Test Case. These are basically the predefined variables and conditions that are used to check whether your application and software is working like it's supposed to.
For a testing process to be successful, then as a competent software developer you will have to learn and understand how to use some of these techniques. Understanding some of these testing methods will make your work so much easier.
Static testing involves the testing of documents and software without actually running the code. Static testing is the opposite to dynamic testing, which requires the code to be ran.
According to Guru99, this can be in the form of walkthroughs, peer reviews, informal reviews and inspections.
Testing the software in the initial phase leads to greater efficiency of the code. Static testing offers just that. During the early development phase, the code undergoes various tests and makes sure that the changes in the current part of the code do not affect the other parts.
The main uses of static testing is that it is tested keeping the work environment in mind. During a review process, the software tester engineer can debate whether a certain form of code is applicable in the real world environment or not.
Testing the software at the early stage before implementing it at a large scale saves a lot of time and more impotantly for any project, is the cost saving.
The outputs from this exercise are typically uncovering deviations from code standards, code that will be hard to maintain in the future, design issues and potentially missing requirements.
System testing requires the code to be ran, whereas static testing does not. It is effectively an offline method to uncover defects early on in the development process.
According to Guru99, there are five major roles in static testing:
The moderator coordinates the activities and tracks the progress of these tasks, to ensure a timely completion.
This person, for example a developer, takes the responsibility of fixing the error that has been identified. This does not have to be a developer, the defect could be a design document, for example. In this situation, an architect may be the author in this context.
This person will keep notes and minutes of meetings. They are typically members of the Project Management Office (PMO), but does not have to be.
As the name suggests, responsible for reviewing defects and providing feedback, to maintain quality.
Manages the process and each individual involved in the static testing activities.
The foremost step of static testing is the review. It is carried out in four stages depending upon its level of formality. The four types of reviews are
These four levels of reviews are inter-connected and intertwined, and work in liaison to collectively bring out an error free code.
All in all, static testing is the most important part of the software testing process which builds the foundation for a flawless software.
Its importance is based on the fact that it is done manually where there is a greater probability of spotting an error and before executing the code itself.
The early stage of the development of a software product lies heavily with the static testing where each bit of error code is identified and rectified making the software error free.
White Box Testing, which is also commonly referred to as Glass Box, Clear Box, Open Box or Structural Testing, is basically all about testing software solution's internal infrastructure and coding.
Its main objectives are to strengthen security, improving usability and design, as well as strengthening the flow of outputs and inputs. This type of testing examines outputs using a particular knowledge of programming code.
The "box testing" approach often used in software testing has two parts to it. One of them is what we're here to discuss, White Box Testing. It's counterpart is known as Black Box testing and this, unlike Clear Box testing, involves the testing of software from an end user type or external perspective.
In White Box testing, the process is concentrated on internal testing and is all about the inner workings of a certain applications.
The concept of a see through box was what was used when coming up with the term "white box". The white box, glass box or clear box name represents the ability to effectively see through the developed software's outer shell right through to its inner workings. Similarly, the "black box" terms used in Black Box testing represents the lack of ability to be able to see the software's inner workings. This approaches main goal is the testing of end user experiences.
So, is White Box testing also called Unit testing? Let's find out. First of all, Unit testing, in computer programming, is a process whereby source-code's individual units are tested to determine whether they are okay for use. An application's smallest testable part is known as a unit.
A unit, in procedural programming, may be an individual procedure or function. Unit tests are occasionally created by testers that use the white box approach or regular programmers.
Each individual test case is, ideally, independent from one another. Substitutes such as mock objects, method stubs, test harnesses and fakes can be used to help test modules in isolation. Software developers are the ones that typically write and run unit tests with the goal of ensuring the code meet the behaviour and design it was intended for.
In White Box testing, if you want to effectively design test cases, you will require adequate programming skills as well as an internal perspective of how the said system works.
For the tester to determine the appropriate output levels, they will need to choose exercise path inputs through the code. It is quite similar to the testing of nodes within a circuit as is experienced in the In-Circuit Testing process (ICT). Clear box testing is normally done at unit level.
It is used to test paths between as well as within units. Hopefully now you can see the difference between the two. The two testing approaches are somewhat different in the few ways explained above.
This type of testing approach can sometimes prove to be quite complex, however, the complexity levels will be determined by the particular application being put through testing.
Small applications, when put through this type of testing, can be completed in a matter of minutes. while larger applications may take several days, and sometimes even several weeks, to complete. White box testing works best during the course of the development of the application software. And with that, hopefully you now know a lot more about White box testing
So, what is Black Box testing also known as? Well, most programmers and developers in the IT realm also commonly refer to this method as "Behavioural Testing", or functional testing.
This testing strategy ignores the application or system's internal mechanisms and mainly concentrates on execution conditions and selected inputs responses.
The program's structure is not taken into consideration in this testing technique. It only takes into account the application's functionality. This testing method is also sometimes referred to as functional testing.
In this strategy, the software tester's main concern is how the application is validated and not how it was produced.
Implementation logic or knowledge of programming isn't required for the software testers that are using this technique. It usually applies at the high levels of testing; System Testing and Acceptance Testing. The software that houses inputs and where you expect the known outputs to be is what IT professionals refer to as a black box.
Transformation of known inputs to known outputs is done using the system and usually goes unchecked in this testing technique. The transformation process in this system is also referred to as a black box.
This technique is basically functional testing whereby development and program testers concentrate on providing the known inputs and checking whether those known inputs have been obtained.
This strategy is usually followed while acceptance testing is being carried out. Here the software developer is merely a user and not the end user.
Here are some benefits of Black Box Testing:
The main thing that makes this technique so different from white box testing is the fact that here the software tester does not really have to have programming knowledge and does not also have to understand the code being used in the application's test procedure, however, it's still effective in very many ways. As a modern-day IT professional you'll need to learn how to use this testing strategy if you want to be fully effective when it comes to modern-day software testing.
Many people ask the question, what is the V Model used for in software testing? Well, the V model is basically the classic waterfall model but in overdrive. Meaning it's an enhanced version.
In this model before a development life cycle can move on to the next level, they must be verified. This basically means that software testing starts as soon as written requirements have been produced, so testing explicitly commences at the very start of the procedure.
Here, the term testing translates to verification by way of inspections and reviews, which is static testing. What this does is it helps you identify errors early, during the life cycles early stages, and also reduces the potential for defects showing up in the software's code in future.
A corresponding test plan is assigned to each level of the development process, that is, each phase that is being worked on is assigned a test plan for the preparation of product testing in that particular phase. Expected results can be can be defined using these developed test plans.
Test and design activities, in the V model, are constructed with the same level of detail. The model's left hand or downhill part is where software is designed while on the model's right hand or uphill part is where it is all built and tested. Correspondences between the right and left-hand side are defined by the line that runs through the center of the V.
These two models approaches are quite similar in very many ways, however, the major difference that sets them apart is the testing emphasis in both situations as well as how they are presented.
The V shape representation flow chart helps point out the differences that come prior to coding such as architecture-design and requirements as well as everything else that follows coding which is testing.
While the waterfall model has testing at 1 out of its 5 steps, the V model methodology basically improves on that significantly.
What all this means is that what makes these two models differ is that for the V Model, for testing activities to fully commence, the development process has to have been completed.
The waterfall method technique seems to be continuously iterative while the V model seems to have a clear start as well as an end. The fact that the V model is a simultaneous process is what makes the approaches differ a little bit.
This happens to be a big reason why most IT professionals prefer to learn, understand and use this method rather than its waterfall counterpart.
All in all, the V Model method should generally be used when you as a programmer or developer are working on small or medium-sized projects, whereby requirements are clearly fixed and defined.
You need to have a high level of confidence in your client if you want the V Model technique to be completely effective. It's an approach than many people doing work in the IT realm should learn and understand for it is one of those things for the future.
Having this knowledge will prove to do more harm than good. Most experts around the globe will agree with this. And with that, now you're in the know. So if you haven't already, start reading up!
So, you want to know all about the ISTQB Foundation level exam right? Luckily for you, you've come to just the right place. This article may be all you need on how to apply for the ISTQB Foundation level exam.
The procedure isn't too difficult. You first get on to the ISTQB website, click on the enrolment tab and you'll be directed to the Login Screen. For 'New Registrations' you'll need to key in your permanent address, personal information, postal address and then finally agree to the conditions and terms provided to you.
You will then be given information containing your User name, Registration number and password. Afterward, you will be required to make a few payments which you will have to do through demand drafts or DDs as they are commonly known. Visit the ISTQB contact link to know where to send the course cost payments.
The International Software Testing Qualifications Board (ISTQB) is basically an internationally operated organisation that does software testing qualification certification.
It was established in 2002 in Edinburgh and is legally registered as a non profit organisation in Belgium. This standardized qualification is an ISTQB Certified Tester that software testers need to undergo in order to obtain certification by the ISTQB.
It is a syllabus based qualification which contains a hierarchy of guidelines and qualifications for the examination and accreditation.
This certification organisation for software testing qualification has managed to issue over five hundred thousand certifications. This Qualifications Board is made up of fifty seven member boards all across the globe and represents about eighty one countries to date.
The Foundation Level exam is designed on a theoretical nature basis and requires the exam taker, hopefully you, to have some knowledge on software development with a slight bias in the software testing field. The Advanced Level exams are much more practical and requires knowledge in specialized areas.
CTFL stands for Certified Tester Foundation Level and its certification training is essential for those of you with interests in the software testing and development industry. The ISTQB accredits this foundation level training which provides its trainees with software testing fundamentals that includes testing management, design techniques as well as testing principles and vocabulary.
This training is usually the first step for those of you that wish to pursue a career in software testing and is meant to measure your proficiency and understanding of software testing techniques, tools and vocabulary. This course is a globally accepted professional certification program that is largely examination based and not an easy one at that.
The foundation level certificate is valid for your whole life, so there is no worries about renewal, regardless of changes to the ISTQB foundation syllabus, once you have this certifcate.
Not to be confused with the partner program. The partner program of the ISTQB has a validity period of one year. People and organisations renewing their partnerships are awarded thirty percent Loyalty Discounts on their Partner fees.
However, partnership levels can be upgraded by individuals or organisations upon request before their one year timeline expires. The only requirement being that you must ensure you're eligible for that upgraded level.
A partner can also terminate their partnership at any time during their validity period upon request. The procedure for this is to contact your Exam provider or Member Board where your program is managed and directly request for your partnership to be cancelled. Simple as that.
The Exam Provider or Member Board involved will then proceed to process your request, get the Partner Program Database and the ISTQB website updated and then finally they will advise the Partner Program Chair of the change and why it has happened. No fees are refunded as a result of the termination.
Software developers and testers basically work hand in hand and testers actually play a vital role.
They receive software builds at various levels of completion and then proceed to put these programs through numerous tests, clearly documenting software response along the way. Documenting is a key component of software testing because it helps software engineers and programmers discover any coding irregularities
Entry level testers with five years experience or less can expect to get paid about around fifty thousand dollars a year, which includes bonuses, overtime pay and tips. Software testers in the middle of their careers, meaning five to ten years experience, can expect an average pay of about sixty eight thousand dollars while those with ten to twenty years experience will be awarded an average salary of about seventy five thousand dollars
And there you have it. All you need to know about this internationally accredited training program and how to apply for the ISTQB Foundation level exam.

Today I am sharing a video I did on the ISEB Testing Foundation Syllabus, and to make it even easier to digest, I have a transcription of the video below. If you are looking for more specific questions, such as how much does the ISTQB foundation exam cost or how many questions are in the ISTQB foundation exam, then we have them covered throughout this site. Anyway, back to the video:
Hey, welcome back guys, this is Wayne Vassell here, again for Talented Tester, and today I'm going to be tackling one of the questions that have been asked a few times and is, "What exactly is in the ISEB Testing Foundation Syllabus?" For those of you that watch in ISEB ISTQB very much use interchangeably, ISTQB is really the standard that we're following now, but this is the specific questing that has been asked.
The syllabus can be found online. Typically, there is five major headings for the syllabus, which are broken down into many different subsections.
The first section we've got is the fundamentals of testing, and that is effectively why is testing necessary, which is broken down to software systems, context, causes of defects, for example what are the root causes of defects, how the defects happen, a real understanding of defects.
The role of testing in software development, and that's maintenance and operations. Testing and quality, understanding exactly what quality is and understanding how much testing is enough.
Obviously if you studied and prepared for these for this exam, you'll know what some of these headings mean and then you should have an idea of how you're actually going to prepare for the exam.
Other areas as well, what is testing, the seven testing principles, fundamental test process, and that is test planing and control, test analysis and design, implementation and execution, evaluating the exit criteria.
Basically with the exit criteria is understand how do you know when to actually exit from testing. Test closure activities, such as test closure reports et cetera. The phycology of testing and finally code ethics. That is the main bulk of the first top level coverage of fundamentals of testing.
The next section is testing throughout the software life cycle, and that encompasses software development models.
For example the V model, iterative incremental development models, testing with a life cycle model. This doesn't really cover such things as agile. Agile is pretty much a new extension, which is almost treated as a separate certification, so that's not covered here. It also goes into test levels, that's component testing, integration testing, system testing and acceptance testing.
Different test types, testing of functions, a functional testing, testing of nonfunctional software, also knows as nonfunctional testing. Structural testing, testing related to changes, for example retesting and regression testing. Other things that covered in this or the last one to be covered in this is maintenance testing.
Hopefully there should a few key things that stick out for you. In my mind the one that's sticks out most is regression testing and retesting. Obviously that's a pretty critical part of testing and regression is pretty much something that you're gonna need throughout your whole testing career and is something good to master.
The next headline topic is static techniques, and this includes the overall static techniques and the test process, the review process, activities of formal review, roles and responsibilities, types of reviews, success factors for reviews and then finally, static analysis by tools.
The next major heading that we've got is test design techniques, and this basically covers the test development process, categories of test design techniques, specification based or black box techniques, and that's including stuff like equivalence partitioning, boundary value analysis, also known as BV, decision table testing, state transition testing and used case testing.
The next subsection within this area is a structured base or white box techniques, and that's statement testing coverage, decision testing and coverage and other structured based techniques. Experienced based techniques and choosing test techniques.
And then the final major area is test management, and this includes test organization, test organization independence, task of test leader. The test studies are mainly to do with being a test lead, so a lot of these to do with actually managing a project or leading a project. The next subsection is to do with test planing and estimation. That's planing, planing the activities, the entry criteria, defining the exit criteria, which was touched on early on in one of the other sections. Test estimation, knowing ... Or not necessarily know, but estimating how long you plan for each test phase, test strategy and test approach, understanding how to layout the strategy, and this would also include the test strategy document. Other subsections are test progress, monitoring and control, which encompasses test reporting, test control. The next subheading, configuration management and then we have also risk in testing, that's project risk and product risks. The final subsection within this area is incident management.
And sorry, the final one, final subheading area is tool support for testing. These are different types of test tools. It goes into the meaning of purposes of the tool, test tool classification, tool support for management, tool support for static testing, tool support for test specification, tool support test execution and [log in 00:06:32], like defect management tools. Tool support for performance and monitoring, like performance testing and tool support for specific testing needs. It then goes into effective use of tools, the potential benefits and risks, and then it talks about special considerations for some of the tools and then it introducing tools for organization.
These are the key areas that are covered within the syllabus. Obviously within each of these headline topics are very much detailed low level sub areas, which I've basically covered at a high level during this video. The key thing really is making sure that you've prepared for each of these sections, so that when you have your multiple choice questions you're prepared to ace the exam, hopefully on your first attempt.
Now, one of the key ways to make sure that you're fully prepared for the exam and make sure that you have the best chance of success is getting a free exam questions and sample test papers that you can use to help you to succeed.
I've got for you at my website TalentedTester.com/Sample is a way for you can download an absolutely free exam and question sample that you can actually use to help you prepare for your exam to give you the best possible choice at chance of succeeding. Thank you very much for watching this video today and I look forward to you in the next video. Thank you very much.

But to give you a brief outline of what to expect, the exams include 40 questions-all multiple choice, which are scored at one point per answer.
The questions are devised to help you with your software testing future, but we recommend getting in as much revision as you can to have the best chance at success!
The pass mark starts at 65%. Given that the questions are all scored on a one point system, which means you’ll need 25+ points to pass the test.
That’s more than half the questions so be prepared and give yourself the best possible chance. The statistics for passing have risen every year so far, you can check out the results here.
As of 2014, almost 75% of people would took the foundation level exam managed to pass on their first try, so the odds are stacked in your favour.
That statistic isn’t just for one country either, that’s the global average! So the majority of people who do take the test, pass, which might help put your mind at ease.
The short answer is, yes you can. You can find an exam provider by using this link. But if you own a business, and you want your employees to benefit from taking the exam in larger numbers, you can use the option of having an in house, or in office, test.
The ITSBQ exam can be done locally as well as online, which offers you the choice that can work best around your lifestyle. The member’s board work internationally as well as locally so if you would prefer to sit the exam in a more traditional setting, there are options available to suit everyone.
Again, the short answer is yes. This makes life all the easier knowing you can print the certificate from home.
Your local ISTBQ member’s board or exam provider will provide you with an email with your certificate attached once you have successfully passed the foundation level.
There are a further two levels of ITSBQ certificates that you can obtain: Advanced level and Expert level, and these can be emailed to you in the same way.
You can also have your certificate posted if you prefer a copy to be directly sent rather than emailed or don’t have easy access to printing facilities.
Once you’ve got the certificate to hand, you’re ready to show it to potential employers, which can offer you a competitive edge against those who have yet to take and pass the exam.
Global exam providers make it easy to obtain an ISTBQ exam in a variety in countries.
Countries that are covered by both the members board and Global exam providers include:

I remember when I was back at uni, my most pressured and unproductive sessions were the last minute, unprepared all nighters. In my opinion, being prepared is the best way.
To cut a long story short, you want to know how many questions are in the ISTQB Foundation exam? The Foundation level exam consists of 40 multiple choice questions which carry one point each.
After completing the exam successfully, you will be issued with an ISTQB Foundation Level Certificate which has a worldwide recognition. The major aim of the exam is to verify the your competence and understanding of the detail in the ISTQB foundation syllabus.
To some people, finding out how many questions are in the ISTQB foundation exam has been a serious challenge.
The ISTQB Certified Tester examination has a typical duration of 60 minutes (or 75 for candidates not taking the exam in their local or native language). As stated earlier, the Foundation level exam consists of 40 multiple choice questions which carry one point each.
The pass mark is set at 65% (scoring 26 or more points). As an option, candidates who are not conversant with the syllabus can take a 3-day course to enable become abreast with the Foundation's examination procedures and methods.
A good number of candidates who book the exam my never end up actually taking the exam, due to the lack of preparation. This could be down to not knowing where to find good study material. Most of them spend their time on the internet searching for the best materials to prepare them for the exam.
To be successful in any exam, getting the correct study materials is very important. The internet is inundated with mediocre study material and past questions which promise heaven on earth and at the end of the day are nothing but empty promises with no substance. Getting hold of some reliable study material is key. One of the reasons we done a review on the best ISTQB foundation Test Analyst books.
What Kind of Study Material Can I Get?
The study materials come in three categories as discussed below:
The dates for ISTQB Foundation Level exams are set by the exam providers. These exam providers are a group of bodies who have been licensed by the Member Boards to administer the exam both locally and internationally at their own convenience. Getting the exact date for the ISTQB Foundation exam depends on your location as the dates differ from region to region. It is therefore advisable that you get acquainted with the local ISTQB exam provider in your location to know the exact date for the examination.
Here is an example of some of the exam providers are listed below in no particular order:
In preparing for the exam, you will need as much time as you can be able to afford. I don’t think your success in the exam depends on the amount of time you studied but how well you were able to study.
You will need all the time you can get to prepare for the exam. A lot of people believe one month is enough to prepare for the exam. This may be true for some people, maybe even many people, but I think it all boils down to your personality and schedule.
If you can commit to it and study the syllabus in one week, it’s all good. Just make sure you are prepared for the examination.
The ISTQB foundation certification comes with a number of benefits for you. Here are a few of the top of my head:
The choice is totally yours. You can take a class to learn the ISTQB fundamentals if you have the time but you are not obligated by the board to do so. You can also take the exams directly as long as you are well prepared and study for it.
The aim of making the syllabus publicly available is for you to be ready for the exam when the date arrives. A lot of people prefer to practice on their own but there are also some classes which you can enrol in if you find it hard to concentrate.
The class can last between a few days, but really depends on the organizers and your time schedule.
Taking the ISTQB exam is very simple if you are prepared for it. During the examination, all you need to do is to relax and choose the right answer as many times as possible. Remember the exam lasts for just 60 or 75 minutes as the case may be.
Try to learn some time management skills while preparing for the exam so that it can come in handy when sitting in the exam hall. In your preparation, seek help as often as you can and be committed to your cause. You can lay hands on some past questions and answers to assist you in your preparation.

Back in 2006 I studied for the ISTQB Foundation Level testing certificate. Fortunately the company I was working for at that time paid for my course, which included some instructor led training. This training included ISTQB mock exam questions that helped me prepare.
Back then it would of been good to read a few books to help me prepare. There are now quite a few good books available on this topic, which I will review for you today.
Nowadays, we live in a world where everyone has a tight schedule and we have forgotten to dedicate some time for personal growth, whether you are a working professional or seeking a testing apprenticeship. Just like a healthy balanced diet and exercise are important to our bodies, reading and acquiring knowledge is crucial to our profession.
Therefore, find some time and improve your skills; it will take you to the next level. Don't say you don't have time. Everyone has 24 hours; the difference is how we manage it.
ISTQB stands for the International Software Testing Qualification Board. It is an international software testing organisation with local exam providers.
Each local testing examiner is licensed to issue exams both locally and internationally. A candidate who passes the exam receives an ISTQB certified tester certificate.
ISTQB is found in seventy nations but the names of each Member Board changes from one country to another. For instance, the member board in the United States is known as the American Software Testing Qualification Board (ASTQB) while in India it is Indian Testing Board (ITB). Nevertheless, the exam syllabus, pattern, questions among other details are the same.
Here are some benefits of the ISTQB testing certification:
ISTQB is classified into three levels, as follows:
Note: our interest here is foundation level certification
It is an entry-level certification and it is designed for individuals who wish to move up the ladder of software testing certification. The main goal of this certification is to ensure you understand key software testing concepts and practices.
Its syllabus covers 6 major topics namely: static techniques such as reviews, black box and white box, test management and testing tools, testing fundamentals, software testing lifecycle.
This is how to enrol for the ISTQB Foundation Certification exam. You will agree with me it is an intuitive, simple and short procedure:
Foundation of Software Testing ISTQB Certification is a good guide to software testing and qualification. This is because covers the fundamental principles as well as syllabus in depth. It also comes with many learning aids.
The Software Testing: An ISTQB-BCS Certified Tester Foundation guide is another ISTQB foundation test analyst study book with basic steps of software testing. It also explains how to do tests effectively. This is because offers an overview of several dynamic and static techniques.
Approximately 300,000 people have done the ISTQB certification examinations. Thanks to contributions of experienced authors like Andreas Spiller, Hans Schaefer, and Tilo Linz with the Software Testing Foundation book.
Andreas Spiller is a computer science professor at Hochschule University where he teaches programming, software engineering, and quality assurance. Tito Linz is the founder and chairman of imbus AG, a big player in the software quality assurance industry. While Hans Schaefer is a consultant who has been teaching and consulting software testing techniques since 1984.
This revised edition covers the entry-level and important software testing techniques. It covers topics like fundamentals of testing, test tools, test management, static and dynamic testing techniques, and testing and software lifecycle.
The Agile Testing Foundations: An ISTQB Foundation Level Agile Tester guide is specifically for the Agile extended certification. It is a simple software development approach that is quickly gaining popularity in the information technology industry. It has many benefits such as offering a wider flexibility scope and enhancing the overall product quality. Back to the ISTQB Foundation level syllabus, this book covers Agile basic principles, techniques, and tools crucial in software testing.
Rex Black, the editor has more than 30 years of software and system engineering experience. He is the former president of ASTQB and ISTQB and a co-author of numerous ISTQB syllabi.
The ISTQB Foundation Exam Sample Question Papers by Katie Graner is another important study tool, it has very many challenging questions.
I have researched many books on software testing and for an entry-level person, I found some too hard to read and with a lot of jargon. This was not until a good friend of mine recommended Foundation of Software Testing. This book covers all software testing areas without using hard language that would make reading hard.
Foundation of Software Testing is a very important book in both software testing and qualification. Currently, in the third edition, the book is completely updated and it includes the latest changes in the ISTQB Foundation syllabus. It also adopts a hand-on and practical approach and covers all important topics that you should know as a software and system tester.
Its authors are developers of the syllabus. They are also renowned and experienced international authors, teachers, authorities and exam setters and markets in software testing field.
All the best in your exams!
I remember my grandad explaining how he worked from an apprenticeship up to a working professional in his trade. In his day that was the norm. Nowadays these apprenticeships are quite rare.
Therefore, if you are lucky enough to be considered for an apprentiship role, you need to absolutly nail the interview!
The best way to do that, is to be 100% prepared, so to help you get prepared I have created an article to help you identify the 5 common questions asked in these interviews. This will be beyond generic questions like what is route cause analysis? and what is software quality? These are real word questions that can help you.
This is a fairly general and basic question that most apprenticeship interviews will begin with. Mainly because interviewers prefer, contrary to what we may believe, to make sure you are comfortable and this is a safe question to ask.
But more importantly, they ask this question to determine your level of interest in the job because as a test analyst your biggest asset is your ability to think critically and have a sharp eye for detail . And neither of these traits will reflect from your work if you don’t enjoy the work you do.
Now that we’ve established why you may come across this question, it is now time to contemplate over how you’ll answer it. You need to be honest. Your answer must show your love and enthusiasm for software testing. I would suggest you narrate an anecdote that pushed you towards this field. And as long as your answer reiterates that becoming a testing analyst was your true calling, you’re good!
This is effectively a question that is judging how badly you want to work with this certain company as well as your expertise in their area of operations. Since, companies prefer hiring people who they’re a first priority for, it’s integral for your research on the company and its projects to be very thorough. This will make you come across as an asset rather than a potential candidate.
Also, your work experiences will come in handy because they will elevate your value by showing that not only are you interested in pursuing data analysis in the future but you also enjoy it. This sort of consistency in a candidate works as a positive signal to the company. Thus, make sure you have a spreadsheet with data about the projects you’ve worked on. This leaves a great impression on the interviewer as you come across as an organised and methodical worker.
This is your window to prove that you can work well in a team. It is a quality truly valued by companies and it would be in your advantage to relate a situation where you participated maturely within a group, any leadership position you took or how you collectively as a group tackled a certain problem.
Make sure you’re not making yourself sound dominating towards the rest of the group. Instead, show how you’re a team player. You can also talk about how much fun you had in your experience, what you learnt from your fellow team members and how you grew from working with them. Finally, express your hope and excitement at the prospect of getting a similar opportunity in the future.
To tackle this sort of question, you must have a strong grip on your basic testing knowledge. It would help to know the various kinds of testing approaches available and how each approach differs from in the other and thus, makes one suitable over the other in different situations.
You must also be aware of the importance of each kind of testing methodology. Moreover, you should be able to pick the one you’re most comfortable using, as well as why you prefer it over the others. It would strengthen your case if you can provide relevant examples or work experience to prove your familiarity with the subject at hand.
Along with this, knowing about the domain and memorizing various data analysis terminologies along with their functions can come in very handy because there will definitely be a question testing your knowledge.
Generally, interviews end with the interviewer presenting a scenario which you will be asked to figure out. You need to understand that as long as your concepts of testing knowledge are clear, you’re in a relatively safe zone. The test here isn’t about your knowledge but about how fast you can think on your feet. So stay calm because if you panic, you’ll cause yourself more harm than good. Therefore, pause for a few minutes and take your time to think.
Don’t rush into it because the answer is never too simple. After you’ve formulated what you have to say, say it with confidence because your outward demeanor speaks volumes about your character especially in stressful situations.
Worse scenario: you’re completely stumped and have no idea. In such situations, it’s essential to remember to not give up without trying. Usually when they see you trying, they tend to help you reach the conclusion. So, don’t lose hope and keep pushing.
In the end, you need to remember to stride in with confidence, trust your instincts, get enough sleep before your interview and keep your CV handy.
These were my five most important interview questions that you can come across at your data analyst apprenticeship interview. Not only will they help you ace the interview with your knowledge about the subject matter but will allow the interviewers a glance into your personality.
For most interviewers, it is the character of an employee that holds most value. Hence, go through this article for when you prep for that interview- which shouldn’t scare you so much anymore. And let me know if these questions helped you in any way. If you liked this article then don’t forget to like, comment and share! Good Luck!
Every day people are faced with problems that need immediate resolution for operations to go on. Also, a lot of times people end up dealing with the matter lightly, only for the issue to resurface. However, to entirely solve a problem, its root cause must be established, and from then on the right steps can be taken to avoid the matter resurfacing.
Root cause analysis (RCA) is the process followed until the chief reason for a problem is determined and eventually solved, helping you to improve quality. Once the source is found and eliminated, you no longer have to worry about the problems you faced reemerging.
For example, you might own a laptop, and you are used to it working fine. All of a sudden, the machine may start responding slowly to commands. Upon rebooting it, the first few minutes it might seem to have regained its efficiency, but soon begins lagging again. At this point there might be several problems causing your laptop to malfunction;
At this moment, all the above are known as causal factors, since you are not yet sure where the exact problem lies.
RCA can be subdivided into several meticulous steps that lead one to find the exact underlying of the problem.
Step 1: Identify all the problem’s causal factors
The initial step in root cause analysis is determining all the issues that may have led to the change in performance. With the earlier mentioned laptop, the reason for the slump in performance might be an internal system problem, like a corrupt operating system.
Similarly, you might have accidentally knocked it and distorted the hard disk, causing it to malfunction. At this point, list all the possible factors that might cause the problem until you have exhausted all of them. The more causal factors you have, the more likely you are to get to the root cause.
According to Towards Data Science, it is never wise to assume that the problem might have only happened when you noticed it. Chances are the root cause may have happened days or even weeks before, and you need to trace the chain of events leading to the problem you are facing.
You now have a list of all the factors that could lead to your misfortune. Since you know that not all of them have the likelihood of causing the trouble you face, rank them in order from the one with the highest possibility to the one with the lowest. Good judgment is needed to narrow down the list efficiently.
With the example of the laptop, lagging can be caused by several factors. A virus in the system, or even an outdated driver software. A virus attacking the computer is a viable reason as viruses insert themselves in the middle of the operating system and start altering system files. You could rule out the possibility of a hardware component causing the issue since you could have already discovered it.
In this stage, you also need to troubleshoot your most potent causal factors until you find the one that solves the problem. For instance, you might try to update all the devices drivers. If the lagging persists, then you know your problem doesn’t lie in the drivers. You can also uninstall some of the programs you recently installed and see if the problem goes away or perseveres.
With your list of a possible factors, ranked from highest to lowest capabilities, the next step of action is determining the root cause. To help you do this, you need to determine what factors can lead to the causal factors. You might have accessed an insecure website while browsing, or you may have even installed a new program on your device before your lagging problem commenced.
You also need to determine other effects the problem might be causing besides just making your laptop lag. The diminished performance might mean you do not finish reports or assignments on time and eventually might land in trouble at school or work. Such additional problems are known as correlated results.
Also, the program you last installed might have caused the lagging because it was affected by a virus. The program, in this case, is called a contributing factor.
You can further break down the program problem into smaller bits to better investigate and understand the problem. Maybe it’s not compatible with your laptop. You might also have downloaded it from an untrusted site, and further installed it without scanning for viruses. Work backward, asking yourself a series of “Why” questions until you arrive at the root cause of the problem.
You have worked your way back on the possible causes of the matter and have concluded that your computer’s lagging is as a result of a virus in the system. This might be true because viruses have the tendency to hide and only affect some programs. An outdated antivirus program will be the root cause of the problem in this case. An up-to-date software can search deep in the system and remove already manifested harmful programs, let alone blocking them from entering the system.
Now that you have updated your antivirus program and the problem has been eradicated, it is up to you to ensure the problem does not surface again. You will only achieve that provided your virus definitions are always updated. If you are forgetful, you can set the program to give you reminders every once in a while.
Root Cause Analysis will always solve the problem from the root itself. In addition to that, it does so in a fast and cost-effective manner. Through this method, you can also find that you create solutions to problems that haven’t even manifested yet, as well as uncover other relationships between problems and their symptoms. Eventually, it also helps you to establish long-lasting solutions to any problem.
Do you know what software programmers dread the most? Testing.
Have you ever encountered a situation where the software you’re using - regardless of whether it’s on the computer, your smartphone or your tablet - didn’t quite give you the result it expected?
Sometimes it’s plain wrong, sometimes just bizarre and sometimes just in a state where stubbornly refuses to give you a response. We’d be surprised if you haven’t, as almost every software ever created has had bugs, errors and defects built into it. Not on purpose, but simply because of the monumental task it is to create 100% perfect quality software.
You could even go so far as to say that quality software isn’t that which is without bugs and errors, it’s that which has the least bugs and errors.
Technically speaking, software quality is the degree to which a software’s performance and features meets the expectations. In other words, is it doing what it’s supposed to do, and does it ever act funny?
In practice, it covers multiple elements, such as design and interface, reliability, reusability, consistency of output and of course, functionality. The better these qualities show themselves in the execution of the software’s operations, the better the software quality.
A software may pass off as satisfactory by providing the right results, regardless of the testing or development model, even if it lacks in the design and durability department. But if defects prevent correct computation, then the software is worth nothing at all. However pretty it might be, you wouldn’t use a calculator that calculated 1 + 1 to be 3, would you?
It then becomes necessary to take software through a stringent quality testing process to ensure that it’s doing it’s job. That’s what we’ll be taking you through today.
Good software is a lot of things. What it definitely isn’t is simply the correct execution of its tasks.
According to Virginia Tech, there are 6 qualities that are a sign of good software.
Specific testing methods can help a developer make sure that each of the requirements are met under various circumstances of use. It has to also be capable of being easily maintained (“maintainability”). What if your client requires a moderate change to the program? An amateur software developer would rewrite the whole program; a good one would have accounted for such a possibility and allowed for modular changes that enable new requirements to fit in snugly with the old program.
“Reliability” and “Reusability” come next. No software is technically 100% reliable, but the aim for a high degree of reliability should always be present. If, under regular operating circumstances, a software fails, and fails often, it is said to be unreliable. In some cases, such as in air traffic control, a minor drop in reliability can have severe consequences. It work hand in hand with correctness and maintainability. Reusability is self-explanatory: can your software be used again, for some other purpose? Has it been designed in such a way that some of its functions may be transmitted to other programs with common requirements, thereby saving you time?
“Portability” is another feature that simply measures how well your software can be used on a wide variety of systems. There are a large variety of computer systems which clients often deal with and you’ll want to be certain that it can run on as many of them as possible. “Efficiency” measures how optimized your program is, in terms of computer resource. Efficient software uses as little as possible, giving your client a better experience overall.
Believe or not, money is one of the biggest consequences of poor software. The enormous time spent in debugging poorly written code results in hundreds of billions of dollars of lost revenue, as discovered by Cambridge University.
Lost time is another result. Clients are stubborn about their requirements, and when you deliver code that is imperfect or downright wrong, they expect it to be corrected - as they should. You’ll only end up wasting more time correcting something that could have been written properly the first time around.
There are far darker consequences as well, depending on the purpose of the software. Stock market crashes and airline delays have been known to have been affected by software bugs. Thousands of people can be stranded halfway across the world, many companies and vested stakeholders lose enormous sums of money because of overlooked errors in the original program. Heaven forbid there being errors in a hospital’s software program.
Broadly speaking, there are three different kinds of faults with software: errors, defects called bugs or faults and failure, according to SoftwareTestingBooks. The first is when the programmer makes a mistake that results in incorrect output. The second when there is some internal mismatch or conflict in a component or series of components of the software that prevents the function from being carried out. The last is when the program simply does not provide the correct result.
It is the defects that are hardest to deal with as they require a close examination of the code.
Test. Test. Test.
And there all kinds of tests. They can be divided into two categories, let’s call them strategic and tactical. Tests that are strategic are automated, manual, exploratory tests, while the tactics used to perform the tests are unit, integration and functional, according to Atlassian.
You can check individual components of the software with unit tests, a subsystem of the program with integration tests and the whole end-to-end process of use with functional tests. These let you narrow down the problem areas.
Computers can be programmed to check the repetitive aspects of the software for correctness, while manual tests are used to check aspects of the software output that usually involve the customer experience. Exploratory testing is like field testing: you get a group of people who broadly represent your software target audience, and give them guidelines to check if it’s working. Essentially, you’re testing the software as if it’s “out there”, though with some supervision, according to Atlassian.
Watch the open lecture on software testing by Professor James Bach (video below). It’s a fantastically entertaining and informative watch that takes you through the whole of software testing.
Software is a quite complex endeavour, though also extremely interesting. At any rate, it is vital if you want to deliver good software and develop a good reputation. You can’t skimp on it!
Software testing is one of the vital phases of software development since some mistakes might be too costly. Projects developing totally new software are commonly challenged with doubts concerning software requirements as well as realization tools.
As a professional software developer, you spend most of your time working with clients that have very limited knowledge about programming, and most of the time, they cannot fully explain what they actually want you to develop.
This little misunderstanding can cause big troubles. In such cases, it is of utmost importance to constantly communicate and gather information from the customer.
If that happens to you, we recommend you to apply the iterative and incremental software development approach (IID) as it allows swift response to alterations, unlike historical methodologies, such as the waterfall model.
Therefore, I decided to provide you with some valuable information about the Iterative-Incremental Development model throughout this article.
Defining Interactive-Incremental Development According to Mockus and Herbsleb (2011) Iterative-Incremental Development is one of the methods of Agile software development, extreme programming and rational integrated procedure.
Iterative-incremental model is an approach of software development, which is formed around a steady enhancement in component additions along with a cyclic releases and pattern upgrading.
It starts with planning and carried out through iterative progression cycles that consist of constant customer response and the incremental computation of extra features, finished with the utilization of completed software before moving onto the next cycle (Larman, 2003).
In short, Incremental is a process of adding new components in small pieces whereas the iterative is a process of acting upon the project repetitively, for example, adding new components in cyclic way.
You first have to identify the software requirements, analyze them, and based on your analysis, you design the software and start coding to develop the designed model. Once you are finished, you conduct with the customer, gather feedback and move onto the next software product increment phase or cycle, where you repeat the steps you took at first cycle, but this time you take those steps based on the freshly gathered feedback and information.
The cycle continuous until the end product is perfectly delivered (Larman, 2003).
The perfect examples of iterative-incremental software development approach can be:
The Pros and Cons of Applying Iterative-Incremental Development Let’s be real. There is no perfect approach to software development and as all the other application development models, the iterative-incremental software development model also has its pros and cons.
Let’s take a look at the advantages that IID offers:
Even though the advantages sound good, a professional programmer should be aware of the following disadvantages of IID:
The Iterative-Incremental Approach is a great software development method, however, a good programmer should know when to actually apply this approach in practice.
If you are completely new to this approach, here are the suggested occasions when you can actually apply this method in your project:
Thus, the product can only be perfectly delivered until going on different cycles of development. Throughout this article, we tried to characterize one of the popular software development methods that widely used in practice nowadays.
Moreover, we decided to include this video tutorial that can help you learn more about Iterative-Incremental Software Development Method:
In this video, the author explains IID approach cycles in great detail.
a constant communication is a fundamental necessity for successful realization of Iterative-Incremental Development method. Particularly uncertainties in the form of shifting requirements may require more communication between the software engineer and client for better understanding and problem solving (Larman, 2003).
Within indecisive working conditions, short iteration phases are required to disclose issues as early as possible. If the iteration cycle is longer, the importance of the communication can be vital for integration part. Without a proper communication and understanding between the parties, it is impossible to successfully implement IID.
