Thanks Em!

I also found this stackoveflow thread useful. In essence:

before :all is not DB transactional. I.e, anything within the before :all persists to the DB and you must manually tear down in the after :all method.

Implications mean that after test suites have completed, changes are not reverted ready for later tests. This can result in complicated bugs and issues with cross contamination of data. I.e, If an exception is thrown the after :all callback is not called.

However, before: each is DB transaction[al].
