根因分析

项目使用 src/ 布局，包未安装（未执行 pip install -e .）且 pytest 的 rootdir 不包含 src/，导致包不在 sys.path 上。

English

The project uses a src/ layout and the package is not on sys.path because it has not been installed (pip install -e .) and pytest's rootdir does not include src/.

解决方案

  1. 95% 成功率 
    pip install -e .
# or with pyproject.toml
pip install -e '.[dev]'
pytest -q
  2. 90% 成功率 
    # pyproject.toml
[tool.pytest.ini_options]
pythonpath = ['src']
testpaths = ['tests']

无效尝试

常见但无效的做法:

  1. 55% 失败

    Duplicates boilerplate across files, breaks when tests run from a different cwd, and hides packaging bugs.

  2. 50% 失败

    Not persisted for CI or other contributors; failures reappear in fresh environments.
