Pytest----关闭所有告警显示

【原文链接】Pytest----如何关闭所有告警显示

通过命令行参数还可以实现关闭所有告警，比如如下代码，这里人工抛出告警。

import warnings

def test_demo1():
    print("in test_demo1 ...")
    warnings.warn(SyntaxWarning("warning，used to test..."))
    assert 1==1

def test_demo2():
    print("in test_demo2 ...")
    warnings.warn(UserWarning("warning，used to demo..."))
    assert 1==1

执行结果如下，可以看出这里报出了两条告警信息。

在命令行使用–disable-warnings 参数即可关闭告警显示，如下所示，这里虽然结果中还显示有2条搞定，但是在会回显中具体告警内容不再显示了。

(demo-HCIhX0Hq) E:\demo>pytest --disable-warnings
=================== test session starts ===================
platform win32 -- Python 3.7.9, pytest-7.2.0, pluggy-1.0.0

test_demo.py ..                                      [100%]

============== 2 passed, 2 warnings in 0.02s ==============

(demo-HCIhX0Hq) E:\demo>

通过在命令行中使用如下参数 -p no:warnings，则可以彻底关闭告警，如下所示，此时结果中根本不会有告警内容的显示以及告警结果的显示。

(demo-HCIhX0Hq) E:\demo>pytest -p no:warnings
