根因分析

pytest-cov 指向的源路径与可导入的包名不匹配，或者测试从未导入该包（例如仅测试导入了不同顶层名称的子模块）。

English

pytest-cov was pointed at a source path that doesn't match the importable package name, or tests never import the package (e.g., only test submodules that import a different top-level name).

解决方案

  1. 95% 成功率 
    pytest --cov=myapp --cov-report=term-missing tests/
  2. 92% 成功率 
    # pyproject.toml
[tool.coverage.run]
source = ["myapp"]
branch = true
  3. 85% 成功率 
    # tests/conftest.py
import myapp  # noqa: F401 ensures coverage sees the package

无效尝试

常见但无效的做法:

  1. 90% 失败

    Branch coverage doesn't fix missing source mapping.

  2. 90% 失败

    Threshold doesn't affect data collection.

  3. 85% 失败

    Extra deps don't fix path/name mismatch.
