根因分析

测试不稳定，意味着由于非确定性行为、竞争条件或外部依赖，它有时通过有时失败。

English

The test is flaky, meaning it sometimes passes and sometimes fails due to non-deterministic behavior, race conditions, or external dependencies.

解决方案

  1. 85% 成功率 
    Look for: random data, time-dependent logic, network calls, shared state, order dependence. Use pytest -p no:randomly to disable random order.
  2. 90% 成功率 
    For random: random.seed(42)
For time: freeze_time or mock datetime.now()
For network: use responses or mock.

无效尝试

常见但无效的做法:

  1. 90% 失败

    This masks the flakiness and can hide real bugs.

  2. 80% 失败

    This stops the test from running and doesn't fix the underlying issue.
