Wrong Logging usage of unexpected test case in initial test run leads to stryker crash

[Dirk-Peters-BF]

Describe the bug Stryker run is aborted due to crash when a specific logging call in VsTestRunner.InitialTest Line 60 is used, when a new unexpected test case is detected in the intial test run.

Expected behavior Stryker does not crash.

Desktop (please complete the following information):

• OS: Linux
• Type of project: core
• Framework Version dotnet core 8
• Stryker Version 4.0.4

Additional context Reason for abort is wrong usage of Microsoft Logging. String interpolation is used in conjunction with parameters. I can provide a fix myself, just need a ticket/justification.

Thanks for reporting. I am working on a fix. Actually, the fix is simple, but I want to activate logging for unit tests to ensure there are no similar issues

[Dirk-Peters-BF]

As mentioned in the ticket, I am actually working on a fix myself but I am including other, similar logging calls. Not necessarily as severe but nevertheless not quite right. My Problem for the described problem is to reproduce outside of the original sources.

[dupdob]

Ok There is a unit test for this situation. Alas, it does not crash as logging is not enabled, so string formatting is simply skipped. So no exception

The opened pull request contains the fix + some logging call harmonizing Since I touched a lot of files for this I'd understand if the pull request is rejected.
