Resharper Unit Test Runner executes unit tests sequentially or in parallel?

Question

I would like to know if Resharper Unit Test runner runs unit tests sequentially or in parallell (each on its own thread). I am using MBUnit test framework.

Thanks.

Answer 1

It does so sequentailly. (using R# 4.0 with VS 2008)

Answer 2

VS2008 + R# 4.5 runs tests in parallel provided that you mark them as such with MbUnit's Parallelizable attribute. If you don't, they will be run sequentially. Either way, it won't run all your tests at once in different threads since that would kill test performance, but rather uses a limited thread pool.
