Environment

  • Pythonnet version: 2.4.0
  • Python version: Python 3.6.0 |Continuum Analytics, Inc.| (default, Dec 23 2016, 11:57:41) [MSC v.1900 64 bit (AMD64)] on win32
  • Operating System: Windows 10 (1803)
  • pytest: 5.3.1

Details

  • Describe what you were trying to get done.

I'm trying to discover and run tests that include calls to clr.AddReference in their module level imports.

  1. Create a pytest test file that looks like this:
import clr

clr.AddReference(r"c:\some_net_dll.dll")

def test_just_a_dummy():
    assert 1 == 1
  1. Replace the reference to a DLL above to a real .net DLL that loads fine when the above file is just run using regular python.exe.
  2. Use VS Code test discovery, or just call pytest --collect-only
  • If there was a crash, please include the traceback here.
