根因分析

pytest-cov插件在测试期间未检测到任何代码执行，可能是因为测试文件未导入源模块，或源代码路径配置错误。

English

The pytest-cov plugin did not detect any code execution during tests, possibly because the test files are not importing the source modules, or the source code paths are misconfigured.

解决方案

  1. 90% 成功率 Ensure test files import the source modules that should be covered 
    In your test file, add: from myproject import mymodule
Then run: pytest --cov=myproject tests/
  2. 85% 成功率 Specify the source directory correctly in pytest.ini or pyproject.toml 
    Add to pyproject.toml:
[tool.pytest.ini_options]
addopts = "--cov=src"
cov_source = ["src"]
Then run pytest.

无效尝试

常见但无效的做法:

  1. Reinstalling pytest-cov via pip 80% 失败

    The issue is not with the installation but with the test configuration or code structure.

  2. Adding `--cov=myproject` without ensuring the source code is actually executed 60% 失败

    If the tests don't import the source modules, coverage still won't collect data.
