根因分析

unittest discover 未找到测试模块：匹配模式不符、起始目录不是包（旧版本缺少 __init__.py），或文件名不符合 test*.py。

English

unittest discover found no test modules because the pattern didn't match, the start directory wasn't a package (missing __init__.py in older versions), or filenames don't match test*.py.

generic

解决方案

  1. 92% 成功率 
    python -m unittest discover -s tests -p 'test_*.py' -v
# Ensure tests/ has __init__.py if using package-relative imports
  2. 88% 成功率 
    git mv tests/foo_tests.py tests/test_foo.py
python -m unittest discover -v

无效尝试

常见但无效的做法:

  1. 85% 失败

    The methods are never executed because discovery fails before collection; prints never run.

  2. 60% 失败

    Default pattern is 'test*.py' (prefix). 'mytest.py' won't match; only 'test_*.py' or 'test*.py' work.
