Django Unit Test- How to avoid rollback for each unit test case
问题
我是新手Django框架。我正在编写Django单元测试案例。每个测试案例的数据库事务都会被回滚。是否有可能避免回滚，因为我希望在其他测试案例中使用该数据库数据？

I am new to Django framework. I am writing Django unit test cases. The DB transactions are getting roll-backed for each test case. Is it possible to avoid the rollback since I want to use that DB data for other test cases?

你可以在测试类中使用 setUp(self) 和 tearDown(self) 方法，它们分别在类范围的初始化之前和之后运行。
也就是说，如果你在测试类的 setUp(self) 方法中创建一个对象，那个对象将对该类中的所有测试可用。
如果你希望在测试类之间共享资源，那么你应该重新评估你试图解决的问题。
这值得一读：
在 Django 中进行测试
英文:
You can use setUp(self) and tearDown(self) methods within a test class, which are run before and after (respectively) for class-wide initialization.
I.e. if you create an object in a test class's setUp(self) method, that object will be available to all tests within that class.
If you want to share a resource between test classes, then you should probably re-evaluate the problem you are trying to solve.

方法 setUpClass 和 setUpTestData 是为此而设计的，它们不会在方法之间回滚。
如果您希望在测试用例类之间保留您设置的状态更长时间，那么 fixtures 可能会有所帮助。 https://docs.djangoproject.com/en/4.2/topics/db/fixtures/
（当说“测试用例”时，您可能指的是测试方法或一个测试用例类 - 人们有时会含糊不清地使用这个术语，所以要小心）
英文:
Methods setUpClass, and setUpTestData, are designed for that, they would not rollback between methods.
If you want keep the state you set up around even longer, between TestCase classes, then fixtures may help. https://docs.djangoproject.com/en/4.2/topics/db/fixtures/
(By saying "test case", you may have meant a test method or a TestCase class - people sometimes use the term vaguely, so take care)
