Does the ReSharper unit test runner run tests sequentially or in parallel with MbUnit?

Question

Does the ReSharper unit test runner run tests sequentially or in parallel (and then, is each test in a separate thread)? I am using MBUnit test framework.

Answer 1

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.

Answer 2

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