pytest doesn't run any test
pytest, python, testing, unit-testing
Solution
To determine why tests are not running, these steps are useful:
- Verify that all files with test cases have a 'test_' prefix.
- Verify that all test case names also have a 'test_' prefix.
- Verify that you have created `pytest.ini` file in the root directory.
- Verify that you have `__init__.py` file in all directories/sub-directories of the project.
Problem
pytest doesn't run any tests and it is not clear why. I tried to use --debug but didn't get any valuable information. It is completely not clear how to debug this sort of issues with pytest. (Looks like some issue with pytest configuration / env variables / test names patterns?) Example of test file: ``` import pytest @pytest.mark.sanity def test_me(): """I'm a test.""" assert True ``` But pytest doesn't run any test, why? ``` $ pytest ================================================== test session starts =================================================== platform linux2 -- Python 2.7.12, pytest-3.1.3, py-1.4.34, pluggy-0.4.0 rootdir: /home/qawizard/pytest-hell, inifile: plugins: xdist-1.15.0, timeout-1.2.0 collected 1 item s !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
