PyCharm has a "Run with Coverage" action for Django test targets. This runs the tests, but shows zero test coverage (0% files, not covered in the project pane, and all red in the editor). Checking or unchecking "Use bundled coverage.py" makes no difference.
Running the same tests from the CLI gives the expected results:
$ coverage --version
Coverage.py, version 3.5.1. http://nedbatchelder.com/code/coverage
$ coverage run ./manage.py test blackbox

2019-04-30. Code coverage is a simple tool for checking which lines of your application code are run by your test suite. 100% coverage is a laudable goal, as it means every line is run at least once. Coverage.py is the Python tool for measuring code coverage.
On the Test menu, select Analyze Code Coverage for All Tests. You can also run code coverage from the Test Explorer tool window. Show Code Coverage Coloring in the Code Coverage Results window. By default, code that is covered by tests is highlighted in light blue.
If you access your project via any symlink in the path, coverage display will fail.
Try to open same project through real path, and you will get correct behavior.
