Pact-JS has beforeEach / afterEach state shooks, but they're a bit of a hack. One problem with this hack is that the afterEach hook is called before the state teardown hooks (which is a bit unintuitive).

It would be neat if the pact core had some reserved state names that it always called before / after each test, meaning that the order could be more easily reasoned about. This would give the beforeEach / afterEach functionality to all pact libraries, too.
