If there are several methods in the test class, I found that the order to execute is alphabetical. But I want to customize the order of execution. How to define the execution order?

For example: testTestA will be loaded first than testTestB.

class Test(TestCase):
    def setUp(self):
        ...

    def testTestB(self):
        #test code

    def testTestA(self):
        #test code
