Code Coverage Analysis

Code Coverage Analysis:
Steps to get code coverage of a module:
1.Instrument the web service binary that you want coverage on: VsInstr.exe /coverage myWebService.dll. The tool executables can be found at \Program Files (x86)\Microsoft Visual Studio 9.0\Team Tools\Performance Tools. So first you need to go to this directory on cmd line to run the command.
For e.g. VsInstr.exe /coverage C:\build\Test10_150\Release\Test.dll
2. Start the monitor for collecting coverage data:
VSPerfCmd.exe /start:coverage /output:C:\CoverageData\150.coverage /cs /user:vkumar.
4.Verify the monitor has started: VSPerfCmd.exe /status:
If you will get an output similar to below message, then the coverage monitor has started:

5. Run the scenario or test cases that will exercise the Windows Service.
Stop the Windows Service and Shutdown the monitor: VSPerfCmd.exe /shutdown. The code coverage data should be saved at C:\CoverageData\150.Coverage. Do not move the .pdb files of the instrumented EXE or DLL. Otherwise, C:\CoverageData\150.Coverage will fail to load.
