Thanks for the article its really nice that you put up everything in detail. I have few queries.
class TestApp(TestWrapper, TestClient):
def init(self):
TestWrapper.init(self)
TestClient.init(self, wrapper=self)

I did not understand this line of code "TestClient.init(self, wrapper=self)". why it is "wrapper = self"?
