Root Cause

A test blocks on a network call, lock, or thread join without a timeout; pytest-timeout's signal method cannot interrupt C-level blocking calls or non-main threads.

generic

中文

测试在没有超时的情况下阻塞在网络调用、锁或线程 join 上；pytest-timeout 的信号方法无法中断 C 层阻塞调用或非主线程。

Workarounds

  1. 93% success 
    import requests
resp = requests.get(url, timeout=5)

# For threads:
thread.join(timeout=5)
assert not thread.is_alive()
  2. 88% success 
    # pyproject.toml
[tool.pytest.ini_options]
timeout = 30
timeout_method = "signal"
# Ensure no test spawns daemon threads that outlive the test

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Merely postpones failure; the underlying hang remains and CI time balloons. Flaky suites still fail on slower machines.

  2. 80% fail

    The thread method cannot kill the stuck thread; it only raises in the main thread, leaving resources leaked and the process hung.
