I would like to know is there any way for us to find test coverage utilizing any code coverage libraries or something similar. For example, for integration testing, I am using automated solutions. If I use any tools like jacoco or something can I find test coverage? For all these years I was using the conventional way of user requirements, traceability matrices, test cases etc. to identify the test coverage. If in an example, I have 100 test cases and I have automated it. I can define the test coverage based on test cases in a conventional way. But how I can ensure which all parts of the actual code have been utilized during the testing.
I am trying to find something more intelligent in the new world. I heard some concepts of Justin hunters hex wise etc. But not have much more idea. Can somebody give me some insights?
