Root Cause

A fixture opens a resource (socket, subprocess, lock) and blocks indefinitely; pytest-timeout aborts the test but the fixture teardown never runs.

generic

中文

fixture 打开资源（socket、子进程、锁）并无限阻塞；pytest-timeout 中止测试但 fixture 的 teardown 从未运行。

Workarounds

  1. 90% success 
    import socket

@pytest.fixture
def server():
    s = socket.socket()
    s.settimeout(5)
    try:
        s.connect(('localhost', 8080))
    except socket.timeout:
        pytest.skip('server not reachable')
    yield s
    s.close()
  2. 85% success 
    pytest --timeout=30 --timeout-method=thread --timeout-func-only -q
# Or set in pytest.ini:
# [pytest]
# timeout = 30
# timeout_method = thread

Dead Ends

Common approaches that don't work:

  1. 70% fail

    The hang is real, not slow; increasing the timeout only delays the failure and wastes CI time.

  2. 90% fail

    Removes the safety net; CI hangs forever.
