Python Django 单元测试 : How to tear down fixtures

Question

我需要为我的 Django 应用程序编写一些测试。为此，我使用的是这样加载的装置:

    from django.test import TestCase    

    class PermissionTest(TestCase):
        fixtures = ['test_groups.json','test_users.json']

        def setUp(self):       
        ... some other stuff

现在我想知道在我的tearDown-Method 中写什么来删除从我的装置生成的组和用户。或者它们会被自动删除？

        def tearDown(self):
            ... what has to go here?

在运行每个测试之前，django 的测试框架将删除已加载的装置。所以你不需要处理这个。

来自docs :

Here’s specifically what will happen:

At the start of each test case, before setUp() is run, Django will flush the database, returning the database to the state it was in directly after migrate was called.

Then, all the named fixtures are installed. In this example, Django will install any JSON fixture named mammals, followed by any fixture named birds. See the loaddata documentation for more details on defining and installing fixtures.

This flush/load procedure is repeated for each test in the test case, so you can be certain that the outcome of a test will not be affected by another test, or by the order of test execution.
