Root Cause

unittest did not discover any tests, often because the test files are not named test_*.py or the test classes do not inherit from unittest.TestCase.

generic

中文

unittest 未发现任何测试，通常是因为测试文件未命名为 test_*.py 或测试类未继承自 unittest.TestCase。

Workarounds

  1. 95% success 
    Rename files to test_*.py and make test classes subclass unittest.TestCase. Use python -m unittest discover -s tests -p 'test_*.py'
  2. 90% success 
    python -m unittest tests.test_module

Dead Ends

Common approaches that don't work:

  1. 95% fail

    unittest discovery relies on the test_*.py pattern; renaming may break discovery further.

  2. 80% fail

    This may run tests if the file has a if __name__ == '__main__' block, but does not fix discovery for all tests.
