separate long test from unit tests in vsts

[yacrumb]

Hello all,

I am used to work with NUnit where I can very easily separate slow
tests from fast tests. I simply create two projects: AcceptanceTests
and UnitTests. If I only want to execute unittests I run that project
only.

How can I achieve this in VSTS with the new artifacts like
testrunconfig, vsmdi-files and testlists?

Thanks in advance!
