MotionSpec

Specs are important! This project makes them a first-class citizen again.

RubyMotion is great at integrating them from the start, but they aren't core to the RubyMotion workflow, and lag behind their distant rspec cousin (RubyMotion's specs are forked from MacBacon, which is a port of Bacon which is a simplified version of rspec).

Add this line to your app's Gemfile:

gem 'motion-spec'

If your Rakefile includes this line you're all set:

Bundler.require

Otherwise, you'll need to add this line to the top of your Rakefile:

require 'motion-spec'

describe AwesomeClass do
  it 'initializes with defaults' do
    expect(AwesomeClass.new.attribute).to eq 'my default'
  end

  it { expect(true).to be_true }

  context 'with a precondition' do
    before { AwesomeClass.build_context }
    after { AwesomeClass.reset_all }

    let(:example_1) { AwesomeClass.new(foo: 'bar') }
    subject { example_1.instance_function }

    it { is_expected.to have_foo('bar') }
  end

  context 'stubbing a method' do
    before { subject.stub!(:awesome_method, return: 'awesomeness') }

    subject { AwesomeClass.new }

    it { expect(subject.awesome_method).to eq 'awesomeness' }
  end
end

mock! ensures that the method is called (and removes the implementation when it is), while stub! simply replaces the method for the duration of the spec.
