根因分析

pytest 的断言重写未能生成详细的内部信息，因为测试模块在插件注册前被导入，或者该模块是未被 pytest 收集的插件/入口点。

English

pytest's assertion rewriting failed to produce detailed introspection because the test module was imported before the plugin registered, or the module is a plugin/entry-point not collected by pytest.

解决方案

  1. 90% 成功率 
    Rename `checks.py` to `test_checks.py` and run `pytest test_checks.py -v`. Ensure no `conftest.py` imports the module early.
  2. 85% 成功率 
    In `conftest.py`: `import pytest; pytest.register_assert_rewrite('myapp.tests.helpers')` then import helpers.

无效尝试

常见但无效的做法:

  1. 60% 失败

    Manual messages still hide the intermediate values of subexpressions, defeating the purpose of assertion rewriting.

  2. 80% 失败

    Disabling plugins also disables assertion rewriting from the built-in plugin, making output worse.
