fixture 'mocker' not found

[kevinjyh]

I am new to pytest. After "clone github" repo, "pip install -e .", and "pytest --durations=0" I got the following error messages: tests/test_mocking_constant_mocker.py, line 6 tests/test_mocking_constant_mocker.py, line 14 tests/test_slow_class.py, line 4 tests/test_slow_function.py, line 12 ... E fixture 'mocker' not found

How can I add pytest fixture'mocker' ErrorMsgs.txt ?

Try installing pytest-mock manually

pip install pytest-mock

If you're using a venv then the above alone won't work. I needed to install pytest-mock at the user level:

pip install --user pytest-mock

Then this worked for me when running pytest inside my venv.

I wish I could explain why that fixed it :thinking:
