Django unit test case code coverage rate statistics-custom test runner

For details about how to write unit test cases in Django and use test_setting and test runner for testing, see the adventures of Django unit test.

CodeIt's easy to understand. I don't have to explain it. If you need to copy the file and modify it as needed, it is not difficult.
