Testing viewDidLoad without using Storyboards

[premedios]

If my UI was being created by code, how would I go about testing the output in the view controller?

You can do it something like below

class MyViewControllerTests: XCTestCase {
// MARK: - Subject under test

var sut: MyViewController!
var window: UIWindow!

// MARK: - Test lifecycle

override func setUp() {
    super.setUp()
    window = UIWindow()
    setupMyViewController()
}

override func tearDown() {
    window = nil
    super.tearDown()
}

// MARK: - Test setup

func setupMyViewController() {
    sut = MyViewController.instance()
    loadView()
    addViewToWindow()
}

func loadView() {
    let _ = sut.view
}

func addViewToWindow() {
    window.addSubview(sut.view)
    RunLoop.current.run(until: Date() as Date)
}

// MARK: - Test doubles

// MARK: - Tests

...

}
