36. OCMock Introducing

37. Objects Mock

38. NSURLRequest *dummyURLRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http:// example.com"]]; PXRequest *requestUnderTest =

    [[PXRequest alloc] initWithURLRequest:dummyURLRequest completion:nil]; id mockConnection = [OCMockObject niceMockForClass:[NSURLConnection class]]; [[mockConnection expect] start]; id partialRequestMock = (PXRequest *)[OCMockObject partialMockForObject:requestUnderTest]; [[[partialRequestMock stub] andReturn:mockConnection] urlConnectionForURLRequest:OCMOCK_ANY]; [partialRequestMock start]; [mockConnection verify]; A Simple Test A lot of Code

39. Why?

40. Because OCMock is OLD and BUSTED
