I’ve been tring to get started with a basic Pytest internal app plugin. According to the v8.1.1 Pytest doc, loading MyPlugin.py in a test_TestPlugin.py file should be possible with pytest_plugins = ["MyPlugin",] in said test_ file. However, running pytest -s gives an ImportError: “No module named ‘MyPlugin'”.

Both plugin & test_ file are located in the same tests/ directory.

MyPlugin.py:

import pytest

@pytest.hookimpl()
def pytest_runtest_setup(item:pytest.Item):
    print("Hook executed!")

test_TestPlugin.py:

pytest_plugins = ["MyPlugin",]

def test_quick():
    assert 1 == 1

I’ve tried:

1. Putting pytest_plugins in conftest.py instead. Gives same ImportError.
2. Prepending “MyPlugin” with the directory both plugin and test_ file are in: pytest_plugins = ["tests.MyPlugin",]. This DOES work, however is not expected nor prefered.

Any and all help is appreciated!
