Hi @djyuran We do not use microsoft Fakes so I cannot confirm or deny if it's supposed to work. We've never tried it. Are COR_PROFILER_PATH and COR_PROFILER some specific environment variables that need to be available in the test process?

I just did a cursory search and it may be related to this: https://stackoverflow.com/questions/41341129/failed-to-resolve-profiler-path-from-cor-profiler-path-and-cor-profiler-environm

Also, it looks like 'OpenCover' find some workaround for this issue: https://github.com/OpenCover/opencover/blob/df7728194c378a5fa06bce4b02c1c321b0b65432/main/OpenCover.Support/Fakes/FakesHelper.cs

We probably need to implement the same workaround then, since we are using vstest directly and not going through visual studio so even if the user has enterprise edition we would not be using those capabilities.

Thanks guys for a quick turnaround! Unfortunately most of the projects in my team use Fakes so I can't onboard Stryker.NET so far but I really want to do that as an excellent tool to check unit test quality.

Just wondering when does enhancement like that usually get implemented? Or it is a open source project and if I need something I should do that?

It is an open source project, and if you can provide time to add something you want we would really appreciate the contribution ;) If you don't have time to do it yourself then it will depend on when one of us or another contributor can find the time to add this feature. We do this in our own time as well, so there's no guarantees.
