用TestComplete进行Silverlight的单元测试

@H_616_18@Silverlight支持ScriptableType 和 ScriptableMember属性，可以让类和成员被外部访问。因此可以用TESTComplete进行调用。

@H_616_18@AutomatedQA网站上的这篇文章介绍了具体的测试方法：

@H_616_18@ 

@H_616_18@单元测试还是在Silverlight程序中创建的，例如：

@H_616_18@namespace NameExtractor
{
    public class UnitTestDriver
    {
       //an object of the tested class NameExtractor
       private NameExtractor nameExtractor;

       public UnitTestDriver()
       {
           nameExtractor = new NameExtractor();
       }

       private void checkEquals(String Expected,String Actual,String Msg)
       {
           if (Expected != Actual)
           {
              String exceptionMsg = String.Format("{0} : expected {1},but was: {2}",Msg,Expected,Actual);
              Exception exception = new Exception(exceptionMsg);
              throw exception;
           }
       }
    }
}

@H_616_18@//tests
public void Test1()
{
    nameExtractor.FullName = "Mr John Greench Brown,PhD";
    checkEquals("Mr",nameExtractor.title,"title is not correct");
    checkEquals("John",nameExtractor.FirstName,"First Name is not correct");
    checkEquals("Greench",nameExtractor.Middlename,"Middle Name is not correct");
    checkEquals("Brown",nameExtractor.LastName,"last name is not correct");
    checkEquals("PhD",nameExtractor.Suffix,"Suffix is not correct");
}

public void Test2()
{
    nameExtractor.FullName = "John Brown";
    checkEquals(""," title is not correct");
    checkEquals("John"," First Name is not correct");
    checkEquals(""," Middle Name is not correct");
    checkEquals("Brown"," last name is not correct");
    checkEquals(""," Suffix is not correct");

    nameExtractor.FullName = "Mr.    John Brown";
    checkEquals("Mr"," Suffix is not correct");

    nameExtractor.FullName = "John Brown,PhD";
    checkEquals("John"," First Name is not correct");
    checkEquals("Brown"," last name is not correct");
    checkEquals("PhD"," Suffix is not correct");
}

@H_616_18@为了让这些单元测试代码能够被TC所调用，需要做一些额外的准备：

@H_616_18@private void Application_Startup(object sender,StartupEventArgs E)
{
    this.RootVisual = new MainPage();
    HtmlPage.RegisterScriptabLeobject("unitTestDriver",new UnitTestDriver());
}

@H_616_18@ 

@H_616_18@添加ScriptableType和ScriptaleMember属性：

@H_616_18@using namespace System.Windows.browser;

namespace NameExtractor
{
    [ScriptableType]  //Provides scriptable access to the entire class
    public class UnitTestDriver
    {
       …
    }
}

@H_616_18@ 

@H_616_18@ 

@H_616_18@ 

@H_616_18@using namespace System.Windows.browser;
namespace NameExtractor
{
    public class UnitTestDriver
    {
       …
       //tests
        [ScriptableMember]   //Provides scriptable access to Test1
       public void Test1()
       {
           …
       }

        [ScriptableMember]   //Provides scriptable access to Test2
       public void Test2()
       {
           …
       }
    }
}

@H_616_18@ 

@H_616_18@ 

@H_616_18@接下来就可以在TC的脚本中调用Silverlight的单元测试代码：

@H_616_18@// JScript

@H_616_18@function GetSlObject()
{
    return Sys.process("IEXPLORE",2).Page("file:///C:/MyProjects/NameExtractor/Bin/Debug/TestPage.html").Form("form1").Panel("silverLightcontrolHost").object(0);
}

@H_616_18@ 

@H_616_18@function Main()
{

@H_616_18@var slObject = GetSlObject();var unitTestDriver = slObject.Content.unitTestDriver;Test1(unitTestDriver);Test2(unitTestDriver);}function Test1(unitTestDriver){try{unitTestDriver.Test1();Log.message("Test1 passed.");}catch(eX){Log.Error("Test1 Failed.",ex.description);}}function Test2(unitTestDriver){try{unitTestDriver.Test2();Log.message("Test2 passed.");}catch(eX){Log.Error("Test2 Failed.",ex.description);}}
