根因分析

pytest-slow-test 插件或自定义钩子标记了超过时间阈值的测试。这是警告而非错误，但如果警告被视为错误，则会导致失败。

English

The pytest-slow-test plugin or a custom hook flags a test that exceeds a time threshold. This is a warning, not an error, but may be treated as an error if warnings are errors.

解决方案

  1. 95% 成功率 
    Use smaller datasets, mock heavy operations, or use caching.
  2. 90% 成功率 
    @pytest.mark.slow
def test_heavy_computation():
    ...
Run with: pytest -m 'not slow'
  3. 85% 成功率 
    @pytest.mark.slow_test_threshold(10)
def test_heavy_computation():
    ...

无效尝试

常见但无效的做法:

  1. 90% 失败

    This reduces coverage and may remove important test cases.

  2. 80% 失败

    This masks the performance issue and may allow very slow tests to persist.

  3. 70% 失败

    If warnings are errors, the test suite still fails.
