根因分析

测试依赖于另一个测试修改的状态，而执行顺序发生变化或测试并行运行。

English

The test depends on state modified by another test, and the order of execution changed or tests are run in parallel.

generic

解决方案

  1. 95% 成功率 
    @pytest.fixture(autouse=True)
def reset_shared_list():
    shared_list.clear()
    yield
  2. 90% 成功率 
    Replace global variables with fixtures that provide fresh instances per test.

无效尝试

常见但无效的做法:

  1. 70% 失败

    This is fragile and does not fix the underlying state leakage; tests may still fail in isolation.

  2. 90% 失败

    This is unreliable and slows down tests.
