python - Pytest cov 不读取 pyproject.toml

Question

Pytest cov 未从 pyproject.toml 文件中读取其设置。我正在使用 nox，所以我使用以下命令运行测试:

python3 -m nox

即使没有 nox，我似乎也有同样的问题。
其实运行了之后 poetry install :

poetry run pytest --cov=src通过测试

poetry run pytest --cov未通过测试

特别是，当测试失败时，我有以下输出(输出被剪切到最重要的内容):

WARNING: Failed to generate report: No data to report.

/Users/matteo/Library/Caches/pypoetry/virtualenvs/project-Nz69kfmJ-py3.7/lib/python3.7/site-packages/pytest_cov/plugin.py:271: PytestWarning: Failed to generate report: No data to report.

  self.cov_controller.finish()

要运行它，您需要 install poetry并到 install nox .

Answer 1

将评论变成答案:
查看当前处理的src目录。现在，它似乎是一个命名空间包，这不是您想要的。要么切换到 src布局:

# pyproject.toml

[tool.poetry]
...
packages = [
    { include = 'project', from = 'src' }
]

[tool.coverage.run]
...
source = ['project']

并修复 test_code.py 中的导入:

from src.project import code

到

from project import code

或删除 src目录:

rootdir
├── project
│   └── __init__.py
└── tests
    └── test_code.py

并修复 test_code.py 中的导入.
