Outlets 0.1.0

Outlets

Outlets provides a set of functions to make validating that IBOutlets are connected between your Storyboard/XIB file and view controller properties. It can also validate that IBAction methods are connected correctly as well.

For an explanation of the approach and how these assertions work see Testing IBOutlets and IBActions With Curried Functions in Swift

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Here is an example of using Outlets with Quick and Nimble:

class ViewControllerSpec: QuickSpec {
    override func spec() {
        setupFailHandler { message in
            if let message = message {
                fail(message)
            } else {
                fail()
            }
        }

        var viewController: UIViewController!

        var hasBarButtonItemOutlet: BarButtonItemOutletAssertion!
        var hasSegmentedControlOutlet: SegmentedControlOutletAssertion!
        var receivesAction: ActionAssertion!

        describe("view controller") {
            beforeEach {
                viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("ViewController")
                viewController.loadView()
                expect(viewController.view).toNot(beNil())

                setupActionValidator { target, action, expectedAction in
                    expect(target) === viewController
                    expect(action).toNot(beNil())
                    if let action = action {
                        expect(action) == expectedAction
                    }
                }

                // Capture the new viewController instance for each test
                hasBarButtonItemOutlet = outlet(viewController)
                hasSegmentedControlOutlet = outlet(viewController)
                receivesAction = action(viewController)
            }

            // MARK: - Outlets
            it("has a leftButton outlet") {
                hasBarButtonItemOutlet("leftButton")
            }
            it("has a rightButton outlet") {
                hasBarButtonItemOutlet("rightButton")
            }
            it("has a segmentedControl outlet") {
                hasSegmentedControlOutlet("segmentedControl")
            }

            // MARK: - Actions
            it("receives a didTapLeftButton: action from leftButton") {
                receivesAction("didTapLeftButton:", from: "leftButton")
            }
            it("receives a didTapRightButton: action from rightButton") {
                receivesAction("didTapRightButton:", from: "rightButton")
            }
            it("receives a segmentedControlValueDidChange: action from segmentedControl") {
                receivesAction("segmentedControlValueDidChange:", from: "segmentedControl")
            }
        }
    }
}
