Spectacular

Spectacular is a BDD framework for CoffeeScript and JavaScript whose attempt to bring the power of RSpec to JavaScript. Spectacular try to favor the best practices used for writing better RSpec tests in its design.

This is the kind of tests you can write with Spectacular:

describe Array, ->
  given 'item', -> foo: 'bar'

  it -> should exist

  itsInstance 'length', -> should equal 0

  describe '::indexOf', ->
    context 'with an item not present in the array', ->
      itsReturn with: (-> [@item]), -> should equal -1

    context 'with an item present in the array', ->
      subject 'array', -> [@item]

      specify 'the returned value', ->
        expect(@array.indexOf @item).to equal 0
