Root Cause

monkeypatch fixture在测试后未正确恢复原始值，导致后续测试受到影响。

generic

中文

monkeypatch未正确恢复，导致测试间状态污染。

Workarounds

  1. 95% success 
    def test_example(monkeypatch):
    monkeypatch.setattr(module, 'attr', 'patched')
    # 测试结束后自动恢复
  2. 90% success 
    with ExitStack() as stack:
    stack.enter_context(patch('module.attr', 'patched'))

Dead Ends

Common approaches that don't work:

  1. 80% fail

    容易遗漏，且与monkeypatch机制冲突。

  2. 70% fail

    pytest的monkeypatch自动处理，手动恢复可能重复。
