Hi! Did you install pytest-cov? This is usually the reason why this error appears, thanks!

Ah yeah there was an error about missing pytest in unittest discovery, so installed the following two packages in a fresh environment.

python -m pip install pytest
python -m pip install coverage

Error:

Failed to import test module: test_wait_parameterized

.vscode/settings.json only had unittest configured

}

Maybe the confusion here was the test explorer shouldn't bring in tests that have pytest in them when configured only for unittests ?

[eleanorjboyd]

yes this is an existing bug here: #23234 sorry about hitting that!
