It currently run all the test without prompt the user to enter any optional arguments to run.exe file. I see that in the solution that you set it all up automatically, and I not sure if it is possible for you to it up to make it optional to enter additional arguments from the user.
I've added some msbuild magic so you can set the test (e.g. 'runnable/traits.d'), the arguments to permute and whether to force rebuilding the test. See the configuration page "Run dmd test suite"
