根因分析

测试文件或类不匹配 pytest 的默认发现模式（test_*.py / *_test.py、Test* 类、test_* 函数），或语法/导入错误阻止了收集。

English

The test file or class does not match pytest's default discovery pattern (test_*.py / *_test.py, Test* class, test_* function), or a syntax/import error prevented collection.

解决方案

  1. 95% 成功率 
    mv tests/math_test.py tests/test_math.py
# class CheckMath -> class TestMath
# def check_add -> def test_add
  2. 90% 成功率 
    # pytest.ini
[pytest]
python_files = *_test.py test_*.py
python_classes = Check* Test*
python_functions = check_* test_*
  3. 88% 成功率 
    pytest --collect-only -q -vv tests/test_math.py

无效尝试

常见但无效的做法:

  1. 95% 失败

    Cache provider has nothing to do with discovery patterns.

  2. 90% 失败

    There are no failures; there are no tests collected.

  3. 90% 失败

    Coverage plugin doesn't affect collection rules.
