  1. PDC09-FT16 Advanced Diagnostics, IntelliTrace™ and Test Automation Habib Heydarian (habibh@microsoft.com) http://blogs.msdn.com/habibh Program Manager Microsoft Corporation

  2. VS2010: Quality as a 1st Class Citizen 1 2 4 3

  3. It Works on My Machine! Write Code Hand-offto Test Test Code File Bug Hand-offto Dev Investigate Bug Resolve as “No Repro”

  4. What is IntelliTrace? Today + = Application Instrumentation Log File IntelliTrace • Record • Playback • Rewind = + = IntelliTrace

  5. IntelliTrace: How Did I Get Here? demo HabibHeydarian Program Manager Visual Studio

  6. IntelliTrace Capabilities • Code is instrumented dynamically • Records program execution flow • Method Enter & Exit • Records program data • Parameters • Return values • Low overhead for collection • Supports Dev, Test and Staging environments • Pay-as-you-go collection model • 1st class debugging experience in VS

  7. IntelliTrace: Why did this Build Verification Test (BVT) test fail? demo HabibHeydarian Program Manager Visual Studio

  8. How IntelliTrace Works Application IntelliTrace Recorder CollectionPlan.xml IntelliTrace File

  9. Choose the Right Tests

  10. Choosing the Right TestsThe Problem Q: Which tests should the developer and tester run to verify this code change? Automated Tests only Manual Tests only All of the above Don’t know Trick question?? Code Change Δ Application Functionality

  11. Choosing the Right TestsThe Consequence The world of Developers The world of Testers Verify more tests than needed Verify too few tests than needed • Run more tests than needed • Run too few tests than needed • Less Productivity • Effort wasted on tests that don’t need to be run • Lower quality • Not enough testing to verify code change

  12. What is Test Impact Analysis? • Automatically pinpoint which tests are impacted as a result of a code change What is the impact of this bug fix?

  13. Test Impact Analysis: A One Line Bug Fix demo HabibHeydarian Program Manager Visual Studio

  14. How Test Impact Analysis Works B A TFS Microsoft Team & Lab Mgr Team Build Test Impact View Manual Impacted Tests C Automated Impacted Tests Team Build Report

  15. Multi-Tier Performance Analysis Client-side Script Database calls

  16. Multi-Tier Performance Analysis Developer: “I wonder where the problem could be???” User: “Why is it taking so long to load the Orders page?” Back End? Front End? Mid Tier?

  17. Performance Analysis Across Multiple Tiers demo HabibHeydarian Program Manager Visual Studio

  18. Solve Complex Debugging Tasks

  19. Collaborative Debugging demo HabibHeydarian Program Manager Visual Studio

  20. DataTips Pin the DataTip to the source code DataTip stays in sync with the source code Toolbar allows the user to pin/unpin a DataTip Context menu for managing values/expressions in the DataTip DataTip changes color to indicate it is a floating window Floating DataTips can be dragged anywhere, and can’t be pinned unless over source code Space provided for comments in the DataTip which can be collapsed/expanded as desired

  21. Debugging a Crash in a Deployed Application using Dump Files demo HabibHeydarian Program Manager Visual Studio

  22. Dump File Summary Page Dump file summary information IL Interpreter for managed property evaluation Operating system and CLR version information Search modules Support for mixed-mode dump files Module Information

  23. Summary • IntelliTrace • Test Impact Analysis • Collaborative Debugging • Debugging Dump Files • Tier Interaction Profiling • Client-side Script Profiling
