  8. 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.

  9. What You’ll Need Visual Studio 2012 Premium or Ultimate C# or VB skills Microsoft Test Manager (optionally) Team Foundation Server (optionally) Testable application

  10. Test Automation Platform Support

  11. demo Coded UI Tests

  12. 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.CloseOnPlaybackCleanup & BrowserWindow.CloseOnPlaybackCleanup to preserve between test methods.

  13. 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));

  14. Test → Windows → Test View → Properties → Select CSV, XML, or Database. this.UIMap.SimpleTestParams.UIMyTextboxEditText = TestContext.DataRow[“col_name"].ToString(); Note: Databinding to test parameters happens automatically when converting from manual test cases Employ Databinding Note: This dialog is currently not available in Visual Studio 2012. Need to hand-edit data connection attributes.

  15. Makes it easier to analyze test run data Assert.AreEqual(foo, bar, "Sales tax total is wrong."); Make Friendlier Assertions

  16. Smile! You’re on Camera Imagepic =this.<top_level_window>.CaptureImage(); //Or for entire desktop: Image pic = UITestControl.Desktop.CaptureImage (); pic.Save(@"c:\file.bmp"); TestContext.AddResultFile(@"c:\file.bmp");

  17. 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>

  18. 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

  19. For actions that may not happen every time Playback.PlaybackSettings.ContinueOnError= true; Continue on Error or

  20. Multiple UI Map Files http://tinyurl.com/MultipleUIMaps Allows you to separate logical collections of controls • Easier to edit independently • Easier to version control • Requires a bit more up-front effort • Doesn’t play well with MTM workflow

  21. Test API • http://testapi.codeplex.com/ • Input Injection APIs • Command-Line Parsing APIs • Visual Verification APIs • Combinatorial Variation Generation APIs • Managed Code Fault Injection APIs • Text String Generation APIs • Memory Leak Detection APIs • Object Comparison APIs • More…

  22. 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

  23. Making Your Applications More Testable • Use a testable application stack • Give names to controls • Use naming conventions and stick with them • If you need to change the names of controls, refactor them along with your tests • Carefully consider the implications of changing UI flows • Educate non-test developers on CUITs • Educate manual testers on CUITs

  24. Playback Settings • Search timeouts • Search behaviors • Error behaviors • See http://tinyurl.com/PlaybackSettings

  25. 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/

  26. 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 • See http://msdn.microsoft.com/en-us/library/ff468125.aspx
