A set of functions that add on to Jasmine and make it look more like RSpec.

This plugin is written in Coffeescript, and looks and feels best when the tests are written in coffeescript as well. That being said, there's nothing to stop you from using it for your javascript testing.

Installation

Add src/jasmine-rspec.js to your jasmine helpers in spec/javascripts/support/jasmine.yml:

helpers:
  - helpers/**/*.js

Examples

See the examples in examples/*.coffee for more detail, but here's a taste:

class BankAccount
  constructor: ->
    @balance = 0
  deposit: (amount) ->
    @balance += amount
  is_in_the_red: ->
    @balance < 0

describe 'BankAccount', ->

  subject -> new BankAccount()

  shared_examples_for 'a store of money', ->
    it -> @should respond_to('deposit')

  context 'initially', ->
    it_should_behave_like 'a store of money', ->
      its 'balance', -> @should equal(0)

  let_ 'paycheck', -> 5

  when_ 'depositing moneys', ->
    subject.deposit paycheck

  then_ ->
    the 'paycheck', -> @should equal(subject.balance)
    its 'balance', -> @should equal(paycheck)
    it -> @should_not be('in_the_red')

    when_ 'i get payed some more', ->
      subject.deposit paycheck
      subject.deposit paycheck

    then_ ->
      its 'balance', -> @should be_divisible_by(paycheck)
