Error running the Coded UI test

Question

Hi,

I am trying to run an coded ui test. It ran till a certain point but after that it gives the following error:

"Test method ScanClient.CodedUITest1.CodedUITestMethod1 threw exception:
Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException: The playback failed to find the control with the given search properties. Additional Details:
TechnologyName:  'MSAA'
ControlType:  'Window'
Name:  'ECM Scan Module - Index Document'
ClassName:  'WindowsForms10.Window'
 ---> System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component."

 

What does this mean and how can I avoid this.

Thanks,

bi-tester,

This means your playback was unable to loacate an MSAA (Winforms) type Window with a title of "ECM Scan Module - Index Document".  The class which this control belongs to is referred to as WindowsForms10.Window in code.  Due to this being a Window, it is likely you have a window with a dynamic title (i.e. it changes depending on cirumstance).

I am going to assume this is the case, to fix this you have a couple options depending on your scenario.

UI Element not found due to Dynamic window name but containing Static name portion:

By default, Coded UI playback will search for the Window Title of the window which a given recorded UI element was found in.   To overcome this, add a default constructor which adds a new search property in the UIMap.cs file which is throwing the UIElement not found exception.  

public partial class UIMap{



public UIMap()

{

this.UIWindow.SearchProperties.Add(UIWindow.PropertyNames.Name,"SomethingStatic", PropertyExpressionOperator.Contains);

} 

You may also use this method to add the possible names your window can have (recommended if it is a small number, using PropertyExpressionOperator.Equals instead of PropertyExpressionOperator.Contains)

This can also be done using the Coded UI test editor

See:

Coded UI Test Editor in Visual Studio 2010 Feature Pack 2

Disregarding Window Title as search property:

 You can use the sample provided on Gautam Goenka's blog to remove the Window Title as a search property.

See:

Hi Paul,

Thank you for your reply, but I am sorry I am not able to solve this problem.

I have tried to change the search properties but I dont know which one I should  choose.

Can you explain this in steps?
