Batch running of VS code coverage tools

I came up a batch file to generate code coverage file as is written in this post.

cl /Zi hello.cpp -link /Profile
vsinstr -coverage hello.exe
start vsperfmon /coverage /output:run.coverage
hello
vsperfcmd /shutdown

However, I got this error message when I run the batch fil开发者_Python百科e.

I had to run vsperfcmd /shutdown manually to finish it. What might be wrong?

This is just a timing issue.

The start vsperfmon /coverage /output:run.coverage command starts up vsperfmon.exe in a separate process.

Concurrently, your script goes on to run hello. If hello is a really simple program, it is possible that it executes and completes before vsperfmon.exe is running and fully initialized. If your script hits vsperfcmd /shutdown before the monitor is up and running, you will get the error you're showing.

vsperfcmd is just a controller/launcher for vsperfmon, so you can use that exclusively in your batch file:

cl /Zi hello.cpp -link /Profile
vsinstr -coverage hello.exe
vsperfcmd /start:coverage /output:run.coverage
hello
vsperfcmd /shutdown

In this case, the first call to vsperfcmd will block until the monitor is up and fully running.

To do this for already instrumented files with an IIS Express application: Get the name of the site from C:\Users\<your user>\Documents\IISExpress\config\applicationhost.config

vsperfcmd /start:coverage /output:run.coverage
"c:\Program Files (x86)\IIS Express\iisexpress.exe" /site:"<that thing you got from applicationhost.config>"

a browser will likely auto launch. click around in your code, do your manual tests.

then to finish

vsperfcmd /shutdown
