Is it not Regression Testing Techniques are the same as Selecting Regression Test Cases?? You select the test cases based on which Technique do you want to use?
@@alawiSahel Selecting regression test cases is the specific action of choosing which tests to run based on the chosen technique. The technique you choose influences how you pick these cases. For example: If using retesting everything, you simply select all existing test cases. If using equivalence partitioning, you select a representative sample of test cases from each identified area. If using module regression, you only select test cases that interact with the changed modules. If using risk-based selection, you analyze code changes and identify areas with higher risk of regression, then prioritize test cases related to those areas.
@@alawiSahelor maybe just the naming (selecting test cases) is confusing and it's more about what should be included in the whole regression test suite. And then based on that you use one of the techniques mentioned - either testing all, selecting based on impacted areas, based on prioritisation
Regression testing is the type of software testing used to verify any modification or update in a software to see that those modifications did not alter the software in anyway. Avo Automation provide best-in-class automated testing platform to make regression testing or any other type of testing easy and error-free.
Thank you very much for explaining the Regression Test in detail. Can you also make a video explaining the difference between Regression and System Tests?
What is Regression Testing? Regression testing is a type of software testing conducted after a code update to ensure that the update introduced no new bugs. This is because new code may bring in new logic that conflicts with the existing code, leading to defects.
I have one question that if we make test suite of sprint 1 because of bug fixes in sprint 2 i.e. test suite 1 then we run it.. now I got bug in sprint 3 so the test suite which I will going to create of sprint 1 & sprint 2 .. we will give name test suite2 or we will continue it in test suite1

@@alawiSahelwas wondering the same . Its confusing

very well explained. your work is much appreciated, Thanks
Glad it was helpful!
Great video, thank you for the quick and concise information.

Very easy and clear explanation
Thank you very much sir for your help
Thank you very much for explaining the Regression Test in detail. Can you also make a video explaining the difference between Regression and System Tests?
The videos are very helpful. Please, create more content.
I agree
Excellent videos to understand the testing process. Tried to send some dollars, but some issues with UPI.
Awesome video! Thank u so much!
Thanks and most welcome.😊
Keep watching for more videos!
This was very easy and educational for me thank you. 🙏
You're very welcome.
Keep watching for more videos and tutorials.
Thanks a lot for everything. You are a good teacher.
This exactly what I m looking for
Thanks life changing content your creating!
So good explanation
Glad you liked it.
Keep watching for more videos!
Mean no of all test suites are different or we will continue all in single test suite?
THANKS DUDE
You're welcome! Keep watching and sharing.
Sir can u tell me who decidea the entry & exit criteria? Plz reply
thank you
Perfect perfect.
Thanks 👍🙏
Welcome 👍! Thank you very much. Keep watching and sharing.

explain test policy concept
Sir , please provide us notes also
I have one question that if we make test suite of sprint 1 because of bug fixes in sprint 2 i.e. test suite 1 then we run it.. now I got bug in sprint 3 so the test suite which I will going to create of sprint 1 & sprint 2 .. we will give name test suite2 or we will continue it in test suite1
Sir answer
