iOS writing unit test involving Mknetworkkit

Question

I tried to run MKNetworkKit in my project, it seemed to be fine. I then created a unit test project and call the engine to make some requests (using the MkNetworkOperation). I get no apparent error but the completionhandler block never get called, and so was the errorblock.

I examined my unit test setup, there's no apparent error, and the whole thing "ran". I just dont get any response. If i switch and do this in my main project, it works.

I have also added all the necessary framework to the unit test project.

One thing i notice is that Reachability message get printed out for the case that worked, but nothing for the case that didnt.

Any clue as to whats going on?

Sounds like you need a semaphore or something similar to block the execution until the request returns. Unit tests run until the end of the method. If they hit the end of the method without an error, they were successful. Since your using MKNetworkKit, the server request is async, so the end of the method is hit before the request is complete. I found a helper class to help with unit tests. I'll try to find it again and link to it with some sample code.

Found it: http://www.touch-code-magazine.com/unit-testing-for-blocks-based-apis/

So it's been a while since I wrote these tests. I'm pretty sure this will work, but you might have to tweak it.

-(void)tests { //setup NSString *key = @"myTestKey"; //test STAssertNoThrow( [API resetPassword:@"[email protected] callback:^(NSDictionary *result) { STAssertNotNil(result, @"reset pass response was nil"]); [[TestSemaphor sharedInstance] lift:key]; } error:^(NSDictionary *error) { STFail(@"reset password failed: %@", error.description); [[TestSemaphor sharedInstance] lift:key]; }], @"reset password failed"); [[TestSemaphor sharedInstance] waitForKey:key]; }
