Root Cause

A test blocks longer than the configured timeout, often due to a network call, deadlock, or an unclosed resource waiting on input.

generic

中文

测试阻塞超过配置的超时时间，通常由网络调用、死锁或未关闭的资源等待输入引起。

Workarounds

  1. 90% success 
    from unittest import mock

def test_fetch(monkeypatch):
    monkeypatch.setattr('myapp.client.requests.get', lambda *a, **k: FakeResp())
    assert myapp.client.fetch()
  2. 85% success 
    # pytest.ini
[pytest]
timeout = 60
timeout_method = signal
# on failure, pytest prints the stack where the test hung

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Hides the underlying hang; CI duration balloons and the real bug (deadlock, missing mock) persists.

  2. 95% fail

    Test suite hangs indefinitely in CI, blocking the whole pipeline until the job-level timeout.

  3. 90% fail

    Loses coverage and leaves the bug in production code undetected.
