Hello, I'm interested in the edk2 CI unit tests(https://github.com/tianocore/edk2/tree/master/.pytool). I tested it in my local. It works well in Windows but does not work in Linux. It looks the NuGet in pytool only has windows version (C:\steven\unit_test_env\Lib\site-packages\edk2toolext\bin\NuGet.exe) but not support the Linux. Below is my detail test steps. Do the edk2 CI unit tests work in Linux? * Windows : c:\steven>py -m venv unit_test_env c:\steven>cd c:\steven\edk2 c:\steven\edk2>c:\steven\unit_test_env\Scripts\activate.bat (unit_test_env) c:\steven\edk2>pip install --upgrade -r pip-requirements.txt (unit_test_env) c:\steven\edk2>stuart_setup -c .pytool/CISettings.py TOOL_CHAIN_TAG=VS2019 (unit_test_env) c:\steven\edk2>stuart_update -c .pytool/CISettings.py TOOL_CHAIN_TAG=VS2019 (unit_test_env) c:\steven\edk2>edksetup.bat (unit_test_env) c:\steven\edk2>edksetup.bat Rebuild (unit_test_env) c:\steven\edk2>stuart_ci_build -c .pytool/CISettings.py TOOL_CHAIN_TAG=VS2019 -a X64,IA32 -t DEBUG --verbose ...
