AMTestHelpers

Installation

AMTestHelpers is available through CocoaPods. To install it, simply add the following line to your test target in your Podfile:

pod "AMTestHelpers"

Usage

Once AMTestHelpers is included in your test target, all calls to the following methods will be stubbed out through the built in method swizzling.

• UIViewController
  • presentViewController: animated: completion:
  • dismissViewControllerAnimated: completion:
• UIResponder
  • becomeFirstResponder
  • resignFirstResponder
  • isFirstResponder

UIViewController

When presentViewController: animated: completion: is called, the property AM_testPresentedViewController will be set to the view controller that should be presented and the completion block will then be called sychronously.

When dismissViewController: animated: completion: is called, the property AM_testPresentedViewController will be set to niland the completion block will then be called sychronously.

Example:

func test_nextButtonIsPressed_presentsNextViewController() {
  // when
  viewControllerBeingTested.nextButtonIsPressed()

  // then
  XCTAssert(viewControllerBeingTested.AM_testPresentedViewController is NextViewController)
}

UIResponder

When becomeFirstResponder is called, the property AM_isFirstResponder will be set to true. When resignFirstResponder is called, it will be set to false. isFirstResponder will return the value of AM_isFirstResponder.

UIAlertController

This library adds an executeHandler() function to UIAlertAction and an executeAction(withTitle:) function to UIAlertController that can be used in your unit tests to programtically call the handler for an action on a UIAlertController.
