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

@AbbeyJackson Swift 3 version updated to Swift 4.2, thanks to @JulioBailon for the original version.

 func checkActionForButton(_ button: UIButton?, actionName: String, event: UIControl.Event = UIControl.Event.touchUpInside, target: UIViewController) -> Bool {
        if let unwrappedButton = button, let actions = unwrappedButton.actions(forTarget: target, forControlEvent: event) {
            var testAction = actionName
            if let trimmedActionName = actionName.components(separatedBy: ":").first {
                testAction = trimmedActionName
            }
            return (!actions.filter { $0.contains(testAction) }.isEmpty)
        }
        return false
    }
