Root Cause

pytest-cov did not collect coverage because the source paths are not specified or the tests did not import the target modules.

generic

中文

pytest-cov 未收集覆盖率，因为未指定源路径或测试未导入目标模块。

Workarounds

  1. 98% success 
    Run: pytest --cov=myapp tests/
Or in pytest.ini:
[pytest]
addopts = --cov=myapp
  2. 90% success 
    Check that test files import the modules under test. Coverage only measures executed code.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Without a path, coverage may not know which files to measure.

  2. 90% fail

    This disables coverage reporting entirely.
