根因分析

在垃圾回收期间发生了无法引发的异常，通常是由于文件或套接字未正确关闭。当设置了 -W error 或警告被配置为错误时，pytest 会将其视为失败。

English

An unraisable exception occurred during garbage collection, often due to a file or socket not being closed properly. pytest treats this as a failure when -W error is set or when the warning is configured as error.

解决方案

  1. 95% 成功率 
    Use context managers or explicit close in teardown:
@pytest.fixture
def resource():
    r = open('file')
    yield r
    r.close()
  2. 80% 成功率 
    In pytest.ini:
[pytest]
filterwarnings =
    ignore::pytest.PytestUnraisableExceptionWarning

无效尝试

常见但无效的做法:

  1. 70% 失败

    This hides the symptom but the resource leak remains, potentially causing other issues.

  2. 80% 失败

    Forcing collection may trigger the warning earlier but does not fix the leak.
