What’s new for testers doing UI automation in VS 2010 Beta2?

We are back in Beta2 with a bunch of new stuff in Coded UI test for UI automation testers. First up, the code generation in Coded UI test has been changed to structure the code in a much more usable and intuitive way:

1. All the UI elements you interact with, whether part of recording or added from the UI control locator, all go into a single UI Map – a single collection of all the UI objects in your test. So, you can now edit objects from a single store

2. Every assertion you add is now a method in itself which takes parameters where you can define the expected value to assert on. So, you can now separate the test into logical actions and assertions

3. The recorded methods also have input parameters defined on them that help make data driving easier to do. So, you can now data drive the method by changing the values of the input parameters that go into the recorded method.

For example, if you were testing the new user sign up in hotmail.com and checking if a certain id’s availability is displayed correctly, you can record steps to open hotmail.com, go to sign up page, enter a particular id and press “check availability” button.

The coded UI test project generated has 4 files – the coded UI test .cs file (TestHotmail.cs) containing the test method, UIMap.uitest file which is an XML representation of all the UI elements and actions/assertions performed on each UI object, the UImap.designer.cs file which is the code-behind for the .uitest file containing code for the objects and actions, the UIMap.cs is a file containing a partial definition of the UImap class to help preserve user customizations to the test code.

TestHotmail.cs – contains the actual test method and invocations to recorded methods and assertions


    public class TestHotmail

    {  [TestMethod]public void TestNewUserSignUp(){





UIMap.designer.cs – contains the definitions of the recorded methods, assertions and UI objects. Plus also contains the parameter class definitions passed into each class

public partial class UIMap    {

        public void GotoSignUpPage()

        {    HtmlInputButton signupButton = this.SignInWindowsInterneWindow.HttploginlivecomlogiClient.SignInDocument.SignupButton;

            // Click 'Sign up' button

            Mouse.Click(signupButton, new Point(47, 11)); }

       public void CheckAvailabilityOfId()

        { HtmlEdit imembernameliveEdit = this.SignupWindowsLiveWinWindow.HttpssignuplivecomsiClient.SignupWindowsLiveDocument.ImembernameliveEdit;

            // Type 'anutthar' in 'imembernamelive' text box

            imembernameliveEdit.Text = this.CheckAvailabilityOfIdParams.ImembernameliveEditText;

           // Click 'Check availability' button

            Mouse.Click(checkavailabilityButton, new Point(88, 15));      }}

// Input parameter into the CheckAvailabilityOfId recorded method

    public class CheckAvailabilityOfIdParams

    {      public string ImembernameliveEditText = "anutthar";    }

Other than that, the CUIT builder has gone through a major redesign and morphed into a stack bar at the bottom of your screen with pop up dialogs for the control locator, actions viewer, generate code etc. More on that in the next post

We’ve also added support for virtualized controls in WPF. You will need to wait until the UI Automation 3.0 APIs are available to get this working though. But this should certainly help WPF programmers trying to write tests on their UI apps.

Go ahead, give CUIT a spin and tell us what you think…

  1. When will UI Automation 3.0 APIs be available? says:

    You mentioned for support of virtualized controls in WPF, UI Automation 3.0 APIs are needed. What is the schedule for that?


  2. When running these tests automatically on a Test Environment in Test Center it seems like the test infrastructure is giving up before the last page load. I see the test agent pop up then "PRXY0007: The request or the response message was incomplete or malformed. An existing connection was forcibly closed by the remote host" shows up in the web browser. Manual tests work fine.

    [Anu] Hmm – no idea. Can you post it on to the forums and ping me if you don't get a response? I'll pursue it internally then

    Did you find a solution for this issue?

    [Anu] What issue?

  4. Pankaj says:


    Any updates on the "PRXY0007: The request or the response message was incomplete or malformed." issue? I think it has something to do with the VSTS proxy server that is used for interacting with the AUT.

    [Anu] Pankaj – yes, sounds like it. Have you filed a bug on http://connect?

    I just came across this issue when testing a webpage. I was getting the error "PRXY0007: The request or the response message was incomplete or malformed." about every second time i accessed the website. I thought it might be an Browser compatibility issue with the webpage so i tried IE and it works.

    The i googled the message and found this site. Its not a compatibility issue with the webpage its a compatibility issue with MTM and Chrome.

    If i start a test case, pause it and then try accessing the webpage i get the issue every time. If MTM is recording your actions it happens about every 2 times, i think this might be time boxed so if it happens 2 times in a short amount of time. If i then stop MTM it works fine

    [Anu] Ryan – could you please post this on http://connect with the appropriate logs I requested for? Thanks
