Figure 2-1. swift internal class Now we can import the class using the @testable keyword, as shown in Figure 2-2. And we can now call the Calculator code and use it in our assertions. Figure 2-2. Calculator tests 28 Chapter 2 ■ Swift Unit Testing setUp The setup method is used to initialize any data or objects before a test is called. For example, setup could include code to write to log files or create objects to be used in the test. setUp() saves you from having to repeat the calls in each test.

Text! as String! text = ("\(res)") } } Create the Model Code The code for our Calculator model is shown in Listing 2-8. We have very simple add, sub, mul, and div functions. Note also that we’re putting a guard around the div operation to protect against dividing by zero. Listing 2-8. swift import Foundation class CalculatorModel { var a: Int! var b: Int! swift in the CalculatorTests directory and add the testAdd() code in Listing 2-9. This file allows us to do some simple unit tests on the add method in the CalculatorModel class.

The operation code calls our CalculatorModel code, which performs the calculations. We need to isolate the operations or model code by putting it in a different class, which then makes it possible to unit test our code. Listing 2-7. ViewController Code import UIKit class ViewController: UIViewController { @IBOutlet var resultsFld: UITextField! )! text! as String! text = ("\(res)") } } Create the Model Code The code for our Calculator model is shown in Listing 2-8. We have very simple add, sub, mul, and div functions.
