In our suite of unit tests, different projects build and populate a new instance of the database. Since upgrading to Resharper 5.0, some of these projects containing tests are run concurrently when I run all tests in the solution. Therefore, multiple copies of the database are being created on top of each other and the tests are failing. Is there a way to specify that tests should run serially? All tests pass when I run the projects individually, but I want to be able to run the entire suite at one time.
