Why do we need to clean coverage and remove all tests after application? What if the user wants to apply a set of tests and then work on other tests, and then apply them again?

FYI: My approval is for the existing changes, in case that cleaning the coverage is suitable

Why do we need to clean coverage and remove all tests after application? What if the user wants to apply a set of tests and then work on other tests and then apply them again?

For your use case showing coverage seems to be useful, but there are a couple of ideological problems:

• All the coverage is cleared when we run a new attempt of generation(previous tests are not showing after applying them to the test suite)
• After applying tests, links from covered lines to the test that covers it become incorrect. So the coverage is not shown in the correct way
• For such a development process, it will also be logical to have all the coverage shown, but we are not collecting such information from already existing tests.

All this led me to the conclusion that we have to either clear coverage and make it just a useful visualization of currently generated tests(as it is now) or refactor how we treat coverage, in general, to make it useful for understanding the not-covered part of the project.

I am voting for the first option, at least for now. @Vladislav0Art @pderakhshanfar @arksap2002 your opinion on it?

My problem is about removing test cases.
If you,
1- After test generation click on Apply to test suite
2- click on cancel after path selector pop up.
3- all tests are gone (and not only coverage info)

Oh, I didn't notice such behaviour, it obviously has to be fixed. I was thinking about the concept of deleting coverage in general
