Hi there, I wanted to briefly follow-up on this. From what I'm seeing, the error is due to pytest trying to write __pycache__ under /Workspace/..., and that filesystem doesn’t support that write mode.
In order to resolve this, I tried adding two command line arguments:
- PYTHONDONTWRITEBYTECODE=1
- --assert=plain
(I also added -p no:cacheprovider, but this is only to avoid writing out the .pytest_cache folder in my Workspace)
After adding these CLI args in pytest, I am finally seeing successful tests!
The same fix works in the equivalent pytest python logic, including:
- sys.dont_write_bytecode = True
- result = pytest.main(["--assert=plain", "-p", "no:cacheprovider", "-q"])
See attached examples.
