根因分析

覆盖率插件 (pytest-cov) 未正确配置以测量目标模块，通常是由于缺少 --cov 选项或模块路径不正确。

English

The coverage plugin (pytest-cov) is not properly configured to measure the target module, often due to missing --cov option or incorrect module path.

解决方案

  1. 95% 成功率 Specify the module to measure using --cov flag. 
    pytest --cov=my_module
  2. 90% 成功率 Configure coverage in pyproject.toml under [tool.coverage.run] section. 
    [tool.coverage.run]
source = ['my_module']

无效尝试

常见但无效的做法:

  1. Adding --cov-report=html without specifying --cov 80% 失败

    Coverage data collection requires --cov to specify the module; without it, no data is collected.

  2. Setting coverage in setup.cfg but not using --cov on command line 70% 失败

    Command-line options override config file; if --cov is missing, coverage may not run.
