How to set coveragerc to test a package with specific tests location

I am implementing tests on a python package and I try to make them with pytest.

The project has the following architecture:

• package_name/
  • __init__.py
  • file1.py
  • file2.py
  • ...
• tests/
  • test_file1.py
  • test_file2.py
  • ...
• setup.py
• setup.cfg
• .coveragerc

How can I setup pytest to launch all the tests with a single command such as:

coverage run setup.py test

I tried a few settings, however it seems like pytest do not find the test files in the tests/ directory.
