根因分析

unittest 发现零个测试，因为测试方法不以 'test' 开头、TestCase 子类名不以 'Test' 开头，或发现路径/模式指向了错误的目录。

English

unittest discovers zero tests because test methods do not start with 'test', the TestCase subclass name does not start with 'Test', or discovery was pointed at the wrong directory/pattern.

解决方案

  1. 95% 成功率 
    import unittest

class TestMath(unittest.TestCase):
    def test_add(self):
        self.assertEqual(1 + 1, 2)

if __name__ == '__main__':
    unittest.main()
  2. 90% 成功率 
    python -m unittest discover -s tests -p 'test_*.py' -v

无效尝试

常见但无效的做法:

  1. 70% 失败

    More verbose output still reports zero tests; the naming problem is unchanged.

  2. 60% 失败

    File naming is necessary but not sufficient; methods must also start with 'test'.
