First, instrument the exe or dll by command
vsinstr -coverage the dll/exe
second, start the performance monitor
VSPerfCmd.exe /start:coverage /output:"D:\Latest.Coverage" /cs /user:"Everyone"
at this time, we could check the status by running command:
VSPerfCmd.exe /status
third, start the windows service and execute the test scenario.
Fourth, shut down the performance monitor tool by
VSPerfCmd.exe /shutdown
Trouble shooting:
on the 64 bit machines, you may could not get the coverage, instead it shows message:
Empty results generated: No binaries were instrumented. Make sure the tests ran, required binaries were loaded, had matching symbol files, and were not excluded through custom settings. For more information see http://go.microsoft.com/fwlink/?LinkID=253731
and in the event view, has error with source: VSPERF
Unable to connect to monitor. Make sure the monitor is started and in the correct mode.
Resolving by:
Run the above command from the tools for x64 machines, it located at
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Team Tools\Performance Tools\x64
