Is it possible to test IBAction?

Question

It is kinda easy to unit test IBOutlets, but how about IBActions? I was trying to find a way how to do it, but without any luck. Is there any way to unit test connection bet

Answer 1

I did it using OCMock, like this:

MyViewController *mainView =  [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[mainView view];

id mock =  [OCMockObject partialMockForObject:mainView];

//testButtonPressed IBAction should be triggered
[[mock expect] testButtonPressed:[OCMArg any]];

//simulate button press 
[mainView.testButton sendActionsForControlEvents: UIControlEventTouchUpInside];

[mock verify];

If IBAction is not connected, the test will fail with error "expected method was not invoked".
