copied!<p>You have this line:</p> <pre><code>[locationManager setDelegate:delegateTarget]; </code></pre> <p>This means that when <code>locationManager:didFailWithError:</code> is called, the object that is passed for the <code>CLLocationManager</code> parameter will be your OCMock object named <code>locationManager</code> - AND NOT <code>trueLocationManager</code>. </p> <p>Your expectation:</p> <pre><code>[[delegateTarget expect] locationManager:trueLocationManager didFailWithError:[OCMArg any]]; </code></pre> <p>So, you are expecting a call that passes the <code>trueLocationManager</code>, but instead the partial mock is passed. Try expecting the partial mock to be passed.</p> <p>OCMock partial mocks, like <code>locationManager</code>, are just proxy wrappers over the real object, but their type is different (that's why you used <code>id</code> instead of real types). </p> <p>This magic works because of the way Objective-C handles calls through message passing. If you read a bit about the <a href="https://developer.apple.com/library/mac/documentation/cocoa/reference/foundation/classes/NSProxy_Class/Reference/Reference.html" rel="nofollow">NSProxy</a> and then you look at the <a href="https://github.com/erikdoe/ocmock" rel="nofollow">OCMock implementation</a> you will truly understand how some backstage stuff works.</p> <p>EDIT:</p> <p>Personally I don't know what do you really want to test. The Apple framework? None of the entities there are your classes/protocols. What are you testing?</p> <p>I guess you have a ViewController that implements the CLLocationManagerDelegate protocol. Mock that class. If your location manager is a property, stub it to return your fake location manager (so that internally the vc uses the fake). Or set the fake locationManager.delegate to be your ViewController. Start the fake location manager.</p> <p>Expect the ViewControllers delegate methods to be called. If your location manager is a singleton, then <a href="http://twobitlabs.com/2011/02/mocking-singletons-with-ocmock/" rel="nofollow">it's a bit tricky to replace it</a> with a fake/stub.</p>
