v0.3.1

New beforeEach() / afterEach() and beforeAll() / afterAll() functions to run code before or after tests.

They can be declared at the top level of a file or inside a describe() block:

• beforeEach() / afterEach(): Run before/after every it() in the same and nested describe() blocks.
• beforeAll() / afterAll(): Run once before/after all tests in the same describe() block (or, at the top level, once before/after the whole file).
