是否可以测试IBAction?

问题描述

对IBOutlets进行单元测试有点容易，但是IBActions呢?我试图找到一种方法，但是没有任何运气.有什么方法可以在View Controller中的IBAction与nib文件中的按钮之间进行单元测试连接的单元测试?

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 between IBAction in a View Controller and a button in the nib file?

推荐答案

我使用OCMock做到了，就像这样:

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];

如果未连接IBAction，则测试将失败，并显示错误未调用预期方法".

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