问题
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:
$ cat test_sanity.py
import pytest
@pytest.mark.sanity
def test_me():
""" I'm a test. """
assert True
But PyTest doesn't run any test:
$ pytest
================================================== test session starts ===================================================
platform linux2 -- Python 2.7.12, pytest-3.1.3, py-1.4.34, pluggy-0.4.0

plugins: xdist-1.15.0, timeout-1.2.0
collected 1 item s
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Exit: Done! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
============================================== no tests ran in 0.13 seconds ==============================================
Why so?
回答1:
To determine why tests are not running, these steps are useful:
- Verify that all files with test cases start with 'test_' word.
- Verify that all test cases names also start with 'test_' word.
- 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
