Solution mode doesn't handle namesakes

Describe the bug Found this bug while trying to reproduce another bug… 😄

But basically, imagine there is a solution with projects Library1 and Library2 and both have class MyClass, both classes are tested in respective test projects Library1.Tests and Library2.Tests.

Judging by logs, Stryker knows what to do:

But then the report…

If I do the renaming - that is, rename classes to Library1.MyClass1 and Library2.MyClass2, the results are reasonable.

That said, this is still confusing in a way, I want some notion of the fact those classes are in different projects - but that’s probably a separate discussion.

Desktop (please complete the following information):

• OS: Windows
• Stryker Version: 3.9.0

Alright. What I originally wanted to confirm is that somewhere between versions 3.7.1 and 3.8.2 (that’s the update I was testing) the files key in JSON reports started showing only the name of the file instead of the full path as it used to be.

Is this what you are talking about also? Or should I create some separate issue for this?

Nope, it was me 🙄😁
