  1. Unit Testing your Silverlight Applications Using the Silverlight Unit Testing Framework By, Ben Dewey Senior Software Developer twentySix New York http://bendewey.com/blog http://twitter.com/bendewey

  2. Assumptions • Basic knowledge of • Silverlight • Unit Testing • Nice to have knowledge of • MSTest

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

  4. Preface • Unit Testing (MSTest) [TestMethod] publicvoidCan_CreateCar() { // Arrange // Act var car = newCar(); // Assert Assert.IsNotNull(car); } • Test Driven Design (TDD) • Testing first and allowing your tests/requirements to drive your design

  5. Original Unit Testing Framework

  6. April 2010 Silverlight Toolkit • http://silverlight.codeplex.com

  7. Context

  8. Setting up the Test Harness • Add Project • Silverlight Unit Testing Applications

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

  10. Asynchronous Unit Tests [TestClass]    public classMainPageTests : SilverlightTest    {         [TestMethod, Asynchronous]        public voidCan_ShowHide_Windows()        {            // Arrangevar controller = new GameController();varmainPage = new MainPage(controller);this.TestPanel.Children.Add(mainPage);varstartWindow = mainPage.FindName("StartWindow") asUIElement;varendWindow = mainPage.FindName("EndWindow") asUIElement;            // Act            // AssertEnqueueDelay(500);EnqueueCallback(() =>            {controller.ShowStartScreen  = false;Assert.AreEqual(Visibility.Collapsed, startWindow.Visibility);Assert.AreEqual(Visibility.Collapsed, endWindow.Visibility);            });EnqueueDelay(500);EnqueueTestComplete();        }     }
