How do specs running in parallel not collide in the database?

Do I need to have multiple test DB connections so that the parallel specs aren't colliding when they seed data in beforeEach? Curious to know how this should be set up or how it is supported. Thanks.

As with any test suites if you want parallel execution to work flawlessly each test needs its own set of data.
