如何禁用内部pytest警告？

Question

我想禁用所有pytest内部警告，如PytestCacheWarning中的pytest.ini，但目前没有成功的机会。以下ini文件无法按预期工作：

[pytest]
filterwarnings:
    ignore::pytest.PytestCacheWarning

正确的方法是什么？注意：我不想禁用所有警告，只想禁用pytest实现中定义的警告

---

最小可复制示例：

1）创建以下结构：

some_dir/
    .pytest_cache/
    test_something.py
    pytest.ini

2）将其放入test_something.py文件中：

def test_something():
    assert False

3）将其放入pytest.ini文件中：

[pytest]
filterwarnings:
    ignore::pytest.PytestCacheWarning

4）不要发出警告

5）运行pytest：

您必须使用导入路径来忽略它：

[pytest]
filterwarnings =
    ignore::pytest.PytestCacheWarning

因此，对于所有pytest警告，您将使用公共基类：

[pytest]
filterwarnings =
    ignore::pytest.PytestWarning
