Assumptions Basic knowledge of Silverlight Unit Testing Nice to have knowledge of MSTest

Overview What is Testing/TDD Setting up the Silverlight Unit Testing Test Harness Basic Unit Test Asynchronous Unit Tests Questions

Preface Unit Testing (MSTest) [TestMethod] public void Can_AddNumbers() { // Arrange var calculator = new Calculator(); // Act var result = calculator.Add(1, 2); // Assert Assert.AreEqual(3, result); } Test Driven Design (TDD) Testing first and allowing your tests/requirements to drive your design

Original Unit Testing Framework

April 2010 Silverlight Toolkit

Setting up the Test Harness Add Project Silverlight Unit Testing Applications

Setting up the Test Harness Add References Microsoft.Silverlight.Testing Microsoft.VisualStudio.QualityTools.UnitTesting.Silverlight Modify App.xaml.cs private void Application_Startup(object sender, StartupEventArgs e) { RootVisual = UnitTestSystem.CreateTestPage(); }

Context

Asynchronous Unit Tests [TestClass] public class MainPageTests : SilverlightTest { [TestMethod, Asynchronous] public void Can_ShowHide_Windows() { // Arrange var controller = new GameController(); var mainPage = new MainPage(controller); this.TestPanel.Children.Add(mainPage); var startWindow = mainPage.FindName("StartWindow") as UIElement; var endWindow = mainPage.FindName("EndWindow") as UIElement; EnqueueDelay(500); EnqueueCallback(() => { // Act controller.ShowStartScreen = false; // Assert Assert.AreEqual(Visibility.Collapsed, startWindow.Visibility); Assert.AreEqual(Visibility.Collapsed, endWindow.Visibility); }); EnqueueDelay(500); EnqueueTestComplete(); } }
