Thanks for your videos. I'm adding here a quick summary for all those that need some notes:
The Seven Testing Principles are:
1. Testing shows the presence of defects, not their absence: Testing can show that defects are present, but cannot prove that there are no defects. Testing
is not a proof of correctness.
2. Exhaustive testing is impossible: Testing everything (all combinations of inputs and preconditions) is not feasible except for trivial cases. Risk analysis, test techniques, and priorities should be used to focus test efforts.
3. Early testing saves time and money: Static and dynamic test activities should be started as early as possible. Testing early in the software development lifecycle helps reduce or eliminate costly changes.
4. Defects cluster together: A small number of modules usually contains most of the defects discovered during pre-release testing, or is responsible for most of the operational failures.
5. Beware of the pesticide paradox: If the same tests are repeated over and over again, eventually these tests no longer find any new defects. Existing tests and test data may need changing, and new tests may need to be written.
6. Testing is context dependent: Testing is done differently in different contexts. Different software project is tested differently.
7. Absence-of-errors is a fallacy: Is impossible to run all possible tests and find all possible defects. It is a fallacy to expect that just finding and fixing a large number of defects will ensure the success of a system.
Thanks for reading. I hope this help you.

Hey, I just started to watch the videos and hands down, they are awesome! Thanks for the information, I'm trying to prepare for the exam. I worked at Ubisoft for 5 years in the Elite QC (Balancing Testing), but I need to change the job to something more interesting, as this doesn't offer enough money for what we do here. Is there any chance to get some samples of questions? Thanks a lot!
Hey Agares,
thank you so much your feedback. You can find more questions and their answers here www.slideshare.net/jannatindia
All the best !!!
Thanks a lot!
Hello Neeraj, thank you for the informative session! Regarding the Pesticide Paradox principle, when the requirements do not change where does the need to modify test cases come from I mean if the tests are prepared properly in the first place(ideal case) there would not be a need to upgrade your tests right?
These are basically from the scope of regression in maintenance. Where we keep repeating the same tests after several updates as well. I hope that makes sense.
hello sir if we are preparing for 2023 exam of istqb ur videos is usefull ?? If you have hard copy of notes plz let me know.
Hi, Thanks for an amazing course, I am preparing for Exam which will be held in 2 weeks, can you please confirm that there weren’t any major changes made in course since 2018 and these videos remain applicable information for 2022 July exams as well? Thank you
Hi Levan,
Yes the syllabus has not been revised since 2018 the latest version of the same can be found on istqb.org itself. Also, the videos are still valid for preparing and appearing for exam in 2022 as well. All the best and Happy Learning!!
@@TMSQUARETECH Thanks for prompt response, Much Appreciated! ❤️
Hello, thank you for the informative and understandable sessions! I just have 1 doubt in the 2 testing principles. What is the difference between principle 2 and 7, at the end both means that 100% testing is not possible
Hey Honney!!
There is big difference and they are unique
#2 - it talks about we can't test an application completely at any point of time.
#7 - It says no matter how much testing you perform you must test the application as per the requirement not just like that.
@@TMSQUARETECH thank you so much for clarification, my doubt is cleared now

Hello Sir, I am preparing the ISTQB foundation exam in Australia. Last month, had attempted ANZTB online exam for 2018 syllabus, but not cleared for few marks. Could you please guide me on how to clear/tips the exam. Again, I am planning for another attempt this month.
Hi Prachi,
Sorry that you couldn’t do well last time. But yeah there is always a next time. First of all you should know where do you lack which chapter, which topic and then explore only those areas in more details. Take up the sample questions and try to understand the language and options’ trickiness. For more details ping me again we can have a quick call to understand further.
@@TMSQUARETECH Thanks for your quick reply. Yes I am focusing those chapters which I am lacking. If you have any dumps or any sample questions, please share. Sure we can connect.
Hi Prachi,

Yes Laxmi. These videos are valid for 2021 as well. As the syllabus remain the same since 2018.
@@TMSQUARETECH thankyou so much. its really understandable or helpful thankuuuuu
@@TMSQUARETECH Hi sir, could you please provide us any latest sample ISTQB papers to do more practice.
Hi Sir I'm preparing for 2023 exam, is this syllabus still applicable for 2023?
Yes it is still applicable. All the best
Are we required to read any book?
If required which book will u suggest?
Hi Shruti,
Not necessarily!! If you think the videos and syllabus are not giving you the clarity then you can prefer a book. You can pick up my book “A Guide to ISTQB Foundation Certification” in amazon or flipkart
@@TMSQUARETECH are you going to conduct live session on the coming Saturday?
@@Localplacesfromlocalpeople Yes! It's ever Saturday between 7 PM to 8 PM IST
