The answer of @kdazzle is correct. I didnt try it because people said that 'Django’s TestCase class is a more commonly used subclass of TransactionTestCase' so I thought it was the same use one or another. But the blog of Jahongir Rahmonov explained it better:

the TestCase class wraps the tests within two nested atomic() blocks: one for the whole class and one for each test. This is where TransactionTestCase should be used. It does not wrap the tests with atomic() block and thus you can test your special methods that require a transaction without any problem.

EDIT: It didn't work, I thought yes, but NO.
