I'm working with the Firebase iOS SDK, and I'm struggling to figure out how to fully-test some of the Firebase method calls using Kiwi.
I'm using an instance of Firebase to "watch" a path:
Firebase *streamsReference = [self.firebaseRef childByAppendingPath:@"streams"];
And then using that streamsReference to observe events:
[streamsReference observeEventType:FEventTypeChildAdded withBlock:^(FDataSnapshot *snapshot) {
// do stuff in the block here
}];
I want to test the effects of the code in the block.
This is what I've got so far:
it(@"should handle incoming connections as a hook for WebRTC", ^{
id mockFirebaseClass = [KWMock mockForClass:[Firebase class]];
// mock Firebase object to handle "/streams" path
id mockFirebaseStreamsReference = [KWMock mockForClass:[Firebase class]];
// return the streams reference object via the mock Firebase object
[mockFirebaseClass stub:@selector(childByAppendingPath:) andReturn:mockFirebaseStreamsReference];
// attempt to capture the block in the second param
KWCaptureSpy *spy = [mockFirebaseStreamsReference captureArgument:@selector(observeEventType:withBlock:) atIndex:1];
// inject the Firebase mock into the test class
classUnderTest.firebaseRef = mockFirebaseClass;
// capture the block from the spy
void(^blockToRun)() = spy.argument;
// call method that will invoke the Firebase observeEventType:withBlock method
[classUnderTest setupIncomingRemoteConnectionHandler];
// run the captured block
blockToRun(nil);
...
... expectations go here
...
});
When I run the test, it's failing with an Argument requested has yet to be captured error - which suggests that I'm nailing things up in the wrong order. Can anyone see where I'm going wrong here?
