override func setUp() {

    super.setUp()

    // Create the window

    window = UIWindow(frame: UIScreen.main.bounds)

    window?.backgroundColor = .clear

    window?.rootViewController = UIViewController()

    window?.makeKeyAndOrderFront(nil)

}

override func tearDown() {

    // Remove the window

    window?.removeFromSuperview()

    window = nil

    super.tearDown()

}

// Test adding five labels

func testAddingFiveLabels() {

    // Create five labels

    let label1 = UILabel()

    let label2 = UILabel()

    let label3 = UILabel()

    let label4 = UILabel()

    let label5 = UILabel()

    // Add the labels to the view

    // Add the labels to the window

    window?.addSubview(label1)

    window?.addSubview(label2)

    window?.addSubview(label3)

    window?.addSubview(label4)

    window?.addSubview(label5)

    // Make sure the labels are displayed

    window?.makeKeyAndOrderFront(nil)

}

// Test adding five labels with different fonts
