@Before runs before each test.
@BeforeClass runs once before any of the tests.

So you can use @BeforeClass to setup mock data that you will use in all of the tests (e.g. if you're testing a class of orders, this might create a list of orders to work with).

And @Before you can use for mock data that needs to be recreated over and over (e.g. you might create a single order object which you will modify in the test and so you want to always start with a blank order before each test runs).

Make sense?
