Adds a done-friendly beforeAll setup to jasmine
jasmine-before-all is a standalone plugin that you can load after jasmine that adds a global
beforeAll function that calls
beforeEach at most one time per callback definition and most importantly plays nicely with
done mechanisms like those found in minijasminenode.
beforeAll is typically a bad idea for unit tests, but if you're using Jasmine for integration tests, it'll probably come in handy as soon as your setup becomes expensive.
Does what it says on the tin. This would pass, for instance:
describe 'intentional pollution'->foo = 0beforeAll -> foo += 1context '1'->Then -> foo == 1context '2'->Then -> foo == 1context '3'->Then -> foo == 1
And if your test runner includes a "done" callback (or you've included one as a helper), this should also work:
describe '(asynchronous) intentional pollution'->bar = 3beforeAllsetTimeout ->bar -= 1done100context '1'->Then -> bar == 2context '2'->Then -> bar == 2context '3'->Then -> bar == 2
