模拟NSWindowController

Question

我有一个Mac应用程序，实际上是一个NSStatusItem，我正在尝试测试它的首选项窗口。我将此代码用作模型，因为它的工作方式与我的代码非常相似，只是我的窗口被初始化并显示在applicationDidFinishLaunching以外的函数中。http://bit.ly/wH6QOk

我收到错误:未调用预期的方法:窗口

我不明白为什么会这样。下面是我的测试代码：

-(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;
}

从您的代码中并不清楚您希望windowController如何指向mockWindowController。你是否像Matt Gallagher的文章中那样实现了类别初始化器和invokeSupersequent代码？

从您的代码中可以看出，windowController是weathervane类的一个属性。我认为最简单的方法是避免尝试覆盖NSWindowController的初始化，而只是将你的模拟传递给你的控制器：

-(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];
}
