.NET Framework 4.7.2 Exception - Not enough information to troubleshoot #2028

Closed Christian-Oleson closed 3 months ago

Christian-Oleson commented 2 years ago

Describe the bug Styker is failing in a .NET Framework project. I do not have enough information to understand what the issue is nor to troubleshoot. I followed the docs found here:

Expected behavior A better handled exception so the user can understand what is occurring. I don't know where to start to troubleshoot based off of the message aside from the Stryker code.

Additional context N/a

Looks like we were unable to analyze your project for some reason, resulting in a linq exception. We probably use SingleOrDefault somewhere where we did not expect to not get a result.

Correct. Ideally, if we can get more information to display to the end-user, that will help troubleshoot. I've not gotten to the point yet where I've figured out what is going on. Even verbose logging is lacking in information.

I think I have a fix for this at least: https://github.com/stryker-mutator/stryker-net/pull/2030

dupdob commented 2 years ago

The associated fix has been released. Is the problem still present?

Technically, this is due to an issue with Buildalyzer not finding a valid MSBuild version to run mutation testing. So if Buidalyzer is having issues, it will still fail.

This might behave better with recent changes
