Objectives•Find more UI regression bugs by employing coded UI tests.
•Build and maintain robust coded UI tests.
•Create coded UI tests which result in fewer false positives.
What You’ll Need
Visual Studio 2012
Premium or Ultimate
C# or VB skills
Microsoft Test Manager
(optionally)
Team Foundation Server
(optionally)
Testable application
Test Automation Platform SupportFully supported platform
Partial solution. Further work required in future to complete
Best efforts with known issues. Users can workaround these cases in the code. No major ongoing investment.
Currently no support but on the roadmap for future releases
Currently no support and none planned for now. Opportunity for partners to add this using the Extensibility support. Docs and samples around extensibility are here.
For latest info refer to this article.
Platform Support Notes
IE7/8/9– HTML/AJAX IE9 partially supported in SP1.
Windows Forms 2.0+.NET Fx Controls fully supported, working on 3rd party support.
WPF 3.5+.NET Fx Controls fully supported, working on 3rd party support.
SharePoint 2007 & 2010 See blog post for more info.
FireFox – HTML/AJAXSupported in Feature Pack 2 for FF 3.5 & 3.6.
SilverlightSupported in Feature Pack 2 for Silverlight 4, in-browser apps.
Windows Win32May work with some known issues, but not officially supported.
Dynamics (Ax)Partially supported – see article. Dynamics CRM web client is supported.
MFCPartial support – Known issues & Workarounds
Citrix/Terminal ServicesThe client (MTM or VS) need to be on the remote machine.
Office Client Apps
IE 6/Chrome/Opera/Safari Opportunity for partners to add this using the Extensibility support. Docs and samples around extensibility are here.Flash/Java

Coded UI Tests
Get Used to Using Using. It’s Useful!
using (ApplicationUnderTest.Launch(this.UIMap.LaunchAppParams.UIMyWindowsFormsAppWindowExePath, this.UIMap.LaunchAppParams.UIMyWindowsFormsAppWindowAlternateExePath)){this.UIMap.SimpleTest();…}
Note: This is required in 2010 only.In 2012, app closes when test run finishes.
Use ApplicationUnderTest.CloseOnPlaybackClea
nup & BrowserWindow.CloseOnPlaybackCleanup
to preserve between test methods.
Understand Searching and Filtering http://tinyurl.com/SearchAndFilter
Searching is used to look for all possible controls
Filtering is used to narrow that list to exactly one match
X, Y is only used to guide where the clicks happen within a control
Mouse.Click(uIGOButton,new Point(19, 18));
Employ Databinding
Test → Windows →Test View → Properties →
Select CSV, XML, or Database.
this.UIMap.SimpleTestParams.UIMyTextboxEditText = TestContext.DataRow[“col_name"].ToString();
Note: Databinding to test parameters happensautomatically when converting from manual test cases
Note: This dialog is currently not available in
Visual Studio 2012. Need to hand-edit data connection
attributes.
Make Friendlier Assertions
Makes it easier to analyze test run data
Assert.AreEqual(foo, bar, "Sales tax total is wrong.");
Smile! You’re on Camera
Image pic = this.<top_level_window>.CaptureImage(); //Or for entire desktop: Image pic = UITestControl.Desktop.CaptureImage ();pic.Save(@"c:\file.bmp");TestContext.AddResultFile(@"c:\file.bmp");
Enable Rich Action Logs
QTAgent32.exe.config:<system.diagnostics> <switches>
<add name="EqtTraceLevel" value="4" /> </switches> </system.diagnostics><appsettings> <add key="EnableHtmlLogger" value="true"/> <add key="EnableSnapshotInfo" value="true"/></appsettings>
Microsoft Test Manager → CUIT Workflow Tips
Mark each step as pass/fail when recording manual tests
Carefully consider which test cases make sense for automation, and when
Use the Automation Status field of test cases to identify candidates for automation
Continue on Error
For actions that may not happen every time
Playback.PlaybackSettings.ContinueOnError = true;or
Multiple UI Map Files http://tinyurl.com/MultipleUIMaps
Allows you to separate logical collections of controls
Easier to edit independentlyEasier to version controlRequires a bit more up-front effortDoesn’t play well with MTM workflow
Test API

Coded UI Test Enhanced Frameworkhttp://cuite.codeplex.com/
Simplifies CUIT code
Eliminates need to maintain multiple UI maps
Logical support for tables
Built and supported by the community
Making Your Applications More Testable
Use a testable application stackGive names to controls
Use naming conventions and stick with themIf you need to change the names of controls, refactor them along with your tests
Carefully consider the implications of changing UI flowsEducate non-test developers on CUITsEducate manual testers on CUITs
Playback Settings
Search timeouts
Search behaviors
Error behaviors
See http://tinyurl.com/PlaybackSettings
Windows Automation API 3.0
If running an O/S prior to Windows 7/2008 R2, install this platform update: http://support.microsoft.com/kb/971513/
What About Load Testing?
Coded UI tests assume they have “control” of the mouse and keyboard
Load testing can be accomplished but you need one machine (physical or virtual) per virtual user
