No. It lacks extension support and it also lacks MSTest support. This means no integrated unit testing. This means coding like it's 1996.
Of course, you can run an NUnit runner separately, or as a custom build step, but, well, that sucks.

I use NUnit/xUnit, and sometimes mspec, and testing from the command line or the N/xUnit GUI is not an issue for me.
FYI, there are even attempts at getting continuous testing working via console, as soon as you save a file in VS the tests are kicked off in the console. I tried it and it "worked", but so far I haven't integrated it into my workflow yet.
