Issue with testing

[hungnguyen9]

I tried to run the tests with VS 2022 but I have the following error messages e.g.:

20251005 19:43:28.641 TRACE:: Extensions.IsDirectoryEmpty(): directory '../../../Data/equity/ftxus/map_files' not found or empty

or

The active test discovery was aborted. Reason: Test host process crashed : 20251005 19:43:21.767 ERROR:: LocalDiskMapFileProvider.GetMapFileResolver(sgx): The specified directory does not exist: ../../../Data/equity/sgx/map_files
Unhandled exception. System.InvalidOperationException: GIL must always be released, and it must be released from the same thread that acquired it.
at Python.Runtime.Py.GILState.Finalize()
at System.GC.RunFinalizers()

Could you please help me with this to show me which configuration went wrong? Thanks!

Hey @hungnguyen9! Sorry but we can't give support for local installs, that's why we strongly suggest using the lean cli. But, that being said TRACE:: Extensions.IsDirectoryEmpty(): directory '../../../Data/equity/ftxus/map_files' not found or empty this is not an error, just a warning. Test host process crashed this seems like python isn't setup correctly.
If u want to go deeper, take a look at our CI workflows https://github.com/QuantConnect/Lean/tree/master/.github/workflows and our image on which they run https://github.com/QuantConnect/Lean/blob/master/DockerfileLeanFoundation

@Martin-Molinero sorry to come across this issue after it has been closed, but just curious about the answer you provided. How does one set up the machine to dev/test if they want to work on an issue. When I just get the code, compile and try to run tests, I'm not able to do so. For most repos, this just works. Are there other steps that I'm missing in order to possibly contribute?

Hi! Did you have the same message error as I did above? If it is the case, then I can tell you that I solved it by fixing the Python configuration (as @Martin-Molinero suggested), as although you want to run only one test in C#, you eventually have to have it right. Hope this helps!

@hungnguyen9 yes, I think same error but I haven't looked in a while since I couldn't get it to work. What did you have to fix? I followed the steps here to set up python. Didn't think I had to do anything else.
