I'm trying to use pytest for the 1st time in my new created app but i'm facing problems with running it. I still receive 'no tests ran in...' message.

My project name is PROJECT, then is my app called diet_app and file tests.py inside the app folder.

How to run tests?

I tried with:

  • pytest
  • pytest tests
  • pytest diet_app

To be more precise - to install PyTest I used:

pip install pytest
pip install pytest-django

I'm working in PyCharm

pytest pycharm django python

pytest-django doesn't actually find tests in a file called tests.py out of the box. If you want to keep using a file called tests.py you'll need to add a pytest.ini file in your top-level directory:

My tests are not being found. Why?

By default, pytest looks for tests in files named test_*.py (note that this is not the same as test*.py) and *_test.py. If you have your tests in files with other names, they will not be collected. Note that Django’s startapp manage command creates an app_dir/tests.py file. Also, it is common to put tests under app_dir/tests/views.py, etc.

To find those tests, create a pytest.ini file in your project root and add an appropriate python_files line to it:

[pytest]
python_files = tests.py test_*.py *_tests.py
