根因分析

测试在 I/O（网络、子进程、锁）上阻塞时间超过配置的超时。pytest-timeout 会终止测试，但底层挂起通常表明缺少 mock 或存在死锁。

English

A test blocks on I/O (network, subprocess, lock) longer than the configured timeout. pytest-timeout kills the test but the underlying hang often indicates a missing mock or a deadlock.

解决方案

  1. 90% 成功率 
    Use the thread method to get a Python traceback at timeout:

pytest --timeout=30 --timeout-method=thread -s
  2. 95% 成功率 
    Mock the blocking dependency (e.g. requests.get) or use a fake server; this usually reveals the missing mock.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Slows the suite and hides the real hang; CI eventually times out at the job level.

  2. 90% 失败

    Hung tests block CI indefinitely, requiring manual cancellation.
