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]

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


Original Unit Testing Framework


April 2010 Silverlight Toolkit

  • http://silverlight.codeplex.com


Context


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 voidApplication_Startup(object sender, StartupEventArgs e){RootVisual = UnitTestSystem.CreateTestPage();}


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();        }

    }
