Question

I have a Mac application, an NSStatusItem really, in which I’m trying to test its preferences window.
I used this code as a model since it works much like my code except that my window is initialized and display in a function other than applicationDidFinishLaunching.

I get the error:
Expected method not invoked: window

I can’t figure out why this happens. Here is my test code:

-(void)testPreferencesInit {    
    mockWindowController = [OCMockObject mockForClass:[NSWindowController class]];
    id mockWindow = [OCMockObject mockForClass:[NSWindow class]];

    [[[mockWindowController expect] andReturn:mockWindow] window];
    [[mockWindow expect] makeKeyAndOrderFront:weathervane];

    [weathervane showPreferences:nil];

    [mockWindowController verify];
    [mockWindow verify];

    id windowController;
    object_getInstanceVariable(weathervane, "windowController", (void **)&windowController);
    GHAssertEqualObjects(windowController, mockWindowController,
                                @"windowController not set on appDelegate");
    GHAssertTrue([[windowController windowNibName] isEqualToString:@"Preferences"], @"Window Controller nib name not set");

    object_setInstanceVariable(weathervane, "windowController", nil);
    mockWindowController = nil;
}

It’s not clear from your code how you expect the windowController to point to mockWindowController. Have you implemented the category initializer and invokeSupersequent code as in Matt Gallagher’s post?

It appears from your code that windowController is a property of your weathervane class. I think the simplest approach would be to eschew trying to override NSWindowController‘s initialization and just pass your mock into your controller:

-(void)testPreferencesInit {    
    mockWindowController = [OCMockObject mockForClass:[NSWindowController class]];
    id mockWindow = [OCMockObject mockForClass:[NSWindow class]];

    [[[mockWindowController expect] andReturn:mockWindow] window];
    [[mockWindow expect] makeKeyAndOrderFront:weathervane];

    weathervane.windowController = mockWindowController;

    [weathervane showPreferences:nil];

    [mockWindowController verify];
    [mockWindow verify];
}
