So far, there is no way of returning the results of the tests run with unittest in any form, except for having the results printed. The purpose of this code is to have the name of the test cases, their indexes, as well as the results (Pass, Fail, Error) as a list. This is extremely used when you want to create a table with the results, as it has all the information needed.
The affected file is the result.py in the unittest library folder.

Can you give an example of how to call getTestsReport()? Thanks
Hi, @Joel. I am glad after almost an year someone replies. Well, I have not used this since then, but from what I remember you need to directly call the method on the TestResult object. So, if result_instance's type is TestResult class, you just perform result_instance.getTestsReport() and it will return an array that you can then parse. I will try it myself if you still cannot make it run.
I signed up for an account just to say "Thanks for this!"
Hi @Cosmin. Thanks for putting this up here. This is very valuable. However, whenever I save the result.py, these changes don't get saved. Is there a way I can save that file with these changes?
