根因分析

unittest 的 subTest 失败会被 pytest 报告，但在使用较旧 pytest 版本或未正确配置 pytest-subtests 插件时，不总是作为独立失败计入 JUnit XML 或退出码。

English

unittest's subTest failures are reported by pytest but not always counted as separate failures in JUnit XML or exit codes when using older pytest versions or the pytest-subtests plugin without proper config.

generic

解决方案

  1. 90% 成功率 
    Install pytest-subtests:
  pip install pytest-subtests
Subtest failures then appear as separate test outcomes in reports.
  2. 85% 成功率 
    Upgrade pytest to >= 7.4 which improved subTest reporting and exit codes.

无效尝试

常见但无效的做法:

  1. 60% 失败

    Changes test IDs and reporting; may break CI dashboards that key on names.

  2. 80% 失败

    Reimplements subTest poorly; loses per-case reporting.
