Adam Chainz的答案frmo django-mysql库:

Answer from Adam Chainz frmo django-mysql library:

在提交之前，InnoDB不会对全文索引进行更改.您可以使用TransactionTestCase来解决此问题.

InnoDB doesn't make changes to full text indexes until commits. You can use TransactionTestCase to get around this.

我将测试类更改为使用TransactionTestCase，现在测试通过了.

I change the test class to use TransactionTestCase and the tests now pass.
