Question

我有一套Coded UI测试，我正在为IE 8中的Web应用程序运行。我可以运行任何单独的测试而不会出错。当我尝试一次运行多个测试时，只有第一个测试运行没有错误;一旦尝试第二次测试，我收到以下错误：

“无法使用已与其基础RCW分离的COM对象。”

这是堆栈跟踪。我应该补充一点，我已经用我自己的定义UI元素的类替换了默认的UIMap：

System.Variant.MarshalHelperConvertObjectToVariant(Object o, Variant& v)
System.StubHelpers.ObjectMarshaler.ConvertToNative(Object objSrc, IntPtr pDstVariant)
Microsoft.VisualStudio.TestTools.UITest.Playback.Engine.IRPFPlayback.ScreenElementFromNativeElement(Object varNativeElement, String technologyName)

将以下行添加到窗口中。

this.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);

例如，

打开Adobe Acrobat窗口

public class UIAdobeAcrobatProWindow : WinWindow
{        
    public UIAdobeAcrobatProWindow()
    {
        #region Search Criteria
        this.SearchProperties.Add(new PropertyExpression(WinWindow.PropertyNames.Name, "Adobe Acrobat Pro", PropertyExpressionOperator.Contains));
        **this.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);**
        this.SearchProperties[WinWindow.PropertyNames.ClassName] = "AcrobatSDIWindow";
        #endregion
    }
}

这将解决问题，我希望。
