根因分析

pytest 找不到指定的测试模块，因为当前工作目录不在 sys.path 中，或者模块路径不正确。

English

pytest cannot find the specified test module because the current working directory is not in sys.path or the module path is incorrect.

解决方案

  1. 90% 成功率 
    Run pytest from the project root directory or use the correct path: `pytest tests/`
  2. 85% 成功率 
    Set PYTHONPATH environment variable: `PYTHONPATH=. pytest`

无效尝试

常见但无效的做法:

  1. 60% 失败

    Modifying sys.path in conftest.py may not apply early enough during collection, and can cause inconsistent behavior across test runs.

  2. 70% 失败

    The --pyargs flag requires the module to be installed as a package; otherwise it fails silently or raises the same error.
