43 Chapter 2 ■ Swift Unit Testing Figure 2-15. Test results We can do a lot more with our Swift unit tests, which we’ll talk about later in this chapter. But it is worth noting that it is simplicity itself to set up and use unit testing with the XCTest library for Swift in Xcode. Unit Testing 102 We touched earlier on what makes a good unit test. At its most basic, a unit test should have the following “first” qualities, which were first coined by Tim Ottinger and Brett Schuchert: • Fast • Isolated • Repeatable • Self-verifying • Timely FIRST Unit Tests There’s no point in writing unit tests unless they finish fast.

SetUp() saves you from having to repeat the calls in each test. Listing 2-2 shows the test code on Ubuntu without using setUp. Listing 2-2. Without setUp class Tests: XCTestCase { var simpleCalc : Calculator! mul(a:2, b:3),6) } } Listing 2-3 shows the same test code with the setup() method. Listing 2-3. With the setUp Method class Tests: XCTestCase { var simpleCalc : Calculator! mul(2,3),6) } } tearDown tearDown is called after each test run. Using our previous example, the code becomes Listing 2-4 and the Calculator object is now destroyed before each test method.
