jasmine-before-all is a standalone Jasmine plugin that adds global `beforeAll` and `afterAll` functions which execute their callbacks only once per definition, playing nicely with Jasmine's `done` mechanisms. It's designed for integration testing scenarios where setup costs are expensive, despite the general recommendation against using `beforeAll`/`afterAll` for unit tests. The plugin is compatible with Jasmine 1.x only due to internal code changes in Jasmine 2.0.
