Root Cause

A test or fixture blocked longer than the configured timeout — often due to a network call without timeout, an unclosed DB connection, or a deadlock in a threaded fixture.

generic

中文

测试或 fixture 阻塞时间超过配置的超时——常见原因是无超时的网络调用、未关闭的数据库连接，或线程 fixture 中的死锁。

Workarounds

  1. 90% success 
    import httpx
r = httpx.get(url, timeout=5.0)

# or requests
requests.get(url, timeout=(3.05, 5))
  2. 85% success 
    # pytest.ini
[pytest]
timeout = 30
timeout_method = signal

# per test
@pytest.mark.timeout(10)
def test_fast(): ...

Dead Ends

Common approaches that don't work:

  1. 75% fail

    Masks the hang; CI still stalls and the underlying deadlock remains, eventually failing at a higher timeout.

  2. 55% fail

    Thread method can't interrupt blocking C calls (e.g., socket recv); the test still hangs and gets killed at signal level.
