FindStrategy with ChildWindows

[Joe]

Hello,

I'm trying to set the Find Strategy to return null to check if a popup window pops up when a user do a certain action. It works for the Navigating to "http://localhost:1314/MSP/default.aspx#lul" alone, but when I test the btnMap click, I get a null reference exception.

Thanks - Joe

UPDATE: I just caught the exception and work my way around it, no more problems!

[TestMethod()]

public void CheckAllTabs()

{

 

     

    //Elements

    _HyperlinkButton btnMap = myApp.FindName<HyperlinkButton>("btnMap");

 

 
  

    System.Threading.Thread.Sleep(3500);

    btnMap.User.Click();

    System.Threading.Thread.Sleep(3500);

    TestErrorPage();

 

    System.Threading.Thread.Sleep(3500);

    myManager.ActiveBrowser.NavigateTo("http://localhost:1314/MSP/default.aspx#lul");

    System.Threading.Thread.Sleep(3500);

    TestErrorPage();

 

}

 

//Checks for popup error Message

public void TestErrorPage()

{

    FindStrategy originalStrategy = myApp.Popups.FirstOrDefault().VisualTree.Find.Strategy;

    try

    {

        myApp.RefreshVisualTrees();

        System.Threading.Thread.Sleep(3500);

 

        //null reference exception occurs

        myApp.Popups.FirstOrDefault().VisualTree.Find.Strategy = FindStrategy.WhenNotVisibleReturnNull;

 

        Button OKButton = myApp.Popups.FirstOrDefault().VisualTree.Find.ByName<Button>("OKButton");

        Assert.IsNull(OKButton);

    }

 

    finally

    {

        myApp.Popups.FirstOrDefault().VisualTree.Find.Strategy = originalStrategy;

    }

 

}
