jasmine_node beforeAll afterAll helper

before-after-all-helper.coffee

# monkey patches jasmine (node) to provide beforeAll and afterAll hooks
#
# be sure to add this file as a helper as described in my answer on SO:

# http://stackoverflow.com/a/22054113/389103
#
# inspired by https://groups.google.com/forum/#!msg/jasmine-js/1LvuiUPunwU/SXPo6PMGSSMJ
#
# targets jasmine-node@1.13.1 and jasmine@1.3.1

beforeAll = (done) ->
  # execute your stuff (i.e. datase connection)
  # assuming you need to execute something asynchronously
  # hence the done callback. if not, do your synchronous
  # work and call done, else call done within the callback
  # of your asynchronous work.

  # establish connection to database for integration tests
  # mongoose.connect()

  done()

env = jasmine.getEnv()

execute = env.execute

env.execute = ->
  beforeAll ->
    execute.call env

afterAll = (done) ->
  # execute your stuff (i.e. database disconnect)
  # assuming you need to execute something asynchronously
  # hence the done callback. if not, do your synchronous
  # work and call done, else call done within the callback
  # of your asynchronous work.

  # mongoose.disconnect()

  done()

runner = env.currentRunner();

postExecute = runner.finishCallback;

runner.finishCallback = ->
  afterAll ->
    postExecute.call runner

This guy is for _one_ time setup and teardown. It doesn't take into account multiple subscriptions/actions (iterate over array of callbacks). That was _not_ my intent here. It's a _one_ time thing.
