根因分析

pytest-cov 的 --cov-fail-under 将总覆盖率与阈值比较。覆盖率基于整个包计算，包括当前测试子集未执行到的文件。

English

pytest-cov --cov-fail-under compares total coverage against the threshold. Coverage is computed on the whole package, including files not exercised by the current test subset.

解决方案

  1. 85% 成功率 
    Scope coverage to changed files in CI:

pytest --cov=app --cov-fail-under=80 --cov-report=term-missing
  2. 90% 成功率 
    Use diff-cover to enforce coverage only on new lines:

diff-cover coverage.xml --compare-branch=origin/main --fail-under=80

无效尝试

常见但无效的做法:

  1. 85% 失败

    Excludes real code from coverage and hides untested paths rather than testing them.

  2. 90% 失败

    Disables the gate entirely and lets coverage regress silently.
