PyTest:自动删除使用 tmpdir_factory 创建的临时目录 [英] PyTest: Auto delete temporary directory created with tmpdir_factory

问题描述

我正在尝试使用 PyTest 的 tmpdir_factory 类似于 教程:

I'm trying to create a temporary directory with a specific name (eg, "data") for all tests within a module using PyTest's tmpdir_factory similar to the tutorial:

@pytest.fixture(scope='module')
def project_file(self, tmpdir_factory):
    return tmpdir_factory.mktemp("data")

我在模块内的一些测试中成功使用了临时目录.但是，运行测试后该目录仍然存在，当我再次运行它们时，我会失败，因为我无法创建名为data"的新临时目录.

I'm using the temporary directory in some tests within the module successfully. However, the directory still exists after running the tests and when I run them again, I get a failure because I cannot create a new temporary directory with name "data".

如何在pytest测试完成后自动删除临时目录data"?tmpdir 参数创建被删除的临时目录，但它没有名称，只有函数作用域.

How can I automatically delete the temporary directory "data" after the pytest tests finish? The tmpdir argument creates temporary directory that is removed but it doesn't have a name and it only has function scope.

推荐答案

你可以在fixture完成后进行清理，例如:

You can cleanup after the fixture is done like:

@pytest.fixture(scope='module')
def project_file(self, tmpdir_factory):
    my_tmpdir = tmpdir_factory.mktemp("data")
    yield my_tmpdir 
    shutil.rmtree(str(my_tmpdir))
