Running MSTEST.exe /publish on a TeamBuild server, what are the prerequisites?

Question

Similarly to How to use MsTest in Continuous Integration without VS?, I want to run mstest.exe on a TeamBuild server.

My context is Trapping Error Status in MSBuild

Answer 1

I've read on the MSDN forums that the /publish functionality of mstest requires purchasing either VS Team Developer or VS Team Test edition. Any lesser editions such as standard/professional or team explorer don't have it.

I'd really like to see some more evidence though, as it seems fairly unreasonable that with "standard" VS2008 you can write and run unit tests, but you arbitrarily can't run them on your build machine :-(

To answer the question:

Should mstest.exe /publish only require Team Explorer, or does it require VSTT and Team Explorer?

It appears that it requires VSTT (which I assume means visual studio team-tester edition)
