使用OCMock测试NSWidowController
我一直试图想出一种方法来使用OCMock对applicationDidFinishLaunching委托进行单元测试。我的NSWindowController在这里实例化，我想测试它。这是我的测试代码：
id mockWindowController = [OCMockObject niceMockForClass:[URLTimerWindowController class]];
[[mockWindowController expect] showWindow:self];
NSUInteger preRetainCount = [mockWindowController retainCount];
[appDelegate applicationDidFinishLaunching:nil];
[mockWindowController verify];
"Test Case '-[URLTimerAppDelegateTests testApplicationDidFinishLaunching]' started.
2011-04-11 08:36:57.558 otest-x86_64[3868:903] -[URLTimerWindowController loadWindow]: failed to load window nib file 'TimerWindow'.
Unknown.m:0: error: -[URLTimerAppDelegateTests testApplicationDidFinishLaunching] : OCMockObject[URLTimerWindowController]: expected method was not invoked: showWindow:-[URLTimerAppDelegateTests testApplicationDidFinishLaunching]
Test Case '-[URLTimerAppDelegateTests testApplicationDidFinishLaunching]' failed (0.005 seconds).
"
self.urlTimerWindowController = [[URLTimerWindowController alloc] init];
[self.urlTimerWindowController showWindow:self];

很缴
和不是同一个对象。你的考试中的与被测班的不同。在这种情况下，笔尖不会加载并不重要。 当您想要测试的方法中实例化对象时，通常无法模拟对象。一种替代方法是在一个方法中实例化对象，然后将其传递给另一个完成设置的方法。然后，您可以测试设置方法。例如：-(void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.urlTimerWindowController = [[URLTimerWindowController alloc] init]; [self setUpTimerWindow:urlTimerWindowController]; } -(void)setUpTimerWindow:(URLTimerWindowController *)controller { [controller showWindow:self]; }：-(void)testSetUpTimerWindowShouldShowWindow { URLTimerAppDelegate *appDelegate = [[URLTimerAppDelegate alloc] init]; id mockWindowController = [OCMockObject niceMockForClass:[URLTimerWindowController class]]; [[mockWindowController expect] showWindow:appDelegate]; // this seems weird. does showWindow really take the app delegate as a parameter? [appDelegate setUpTimerWindow:mockWindowController]; [mockWindowController verify]; [appDelegate release]; }
