根因分析

测试阻塞在网络 I/O、未关闭的套接字、死锁或无限循环上；pytest-timeout 在配置的阈值后终止了它。

English

A test blocked on network I/O, an unclosed socket, a deadlock, or an infinite loop; pytest-timeout killed it after the configured threshold.

无效尝试

常见但无效的做法:

  1. 85% 失败

    Extends CI time without fixing the underlying hang.

  2. 95% 失败

    CI hangs indefinitely; hides the bug.

  3. 90% 失败

    A hang is not flakiness.
