  require 'flexmock/test_unit'
  require 'spec'

Spec::Runner.configure do |config|
    config.mock_with :flexmock
  end

  describe "Using FlexMock with RSpec" do
    it "should be able to create a mock" do
      m = flexmock(:foo => :bar)
      m.foo.should === :bar

$ spec spec/account_spec.rb --format nested
Account
  transfering money
    deposits transfer amount to the other account
    reduces its balance by the transfer amount

Scenario: stub in before
  Given the following spec:
    """
    describe "a stub in before" do
      before(:each) do
        @messenger = mock('messenger').as_null_object
      end

      it "a" do
        @messenger.should_receive(:foo).with('first')
        @messenger.foo('second')
        @messenger.foo('third')
      end
    end
    """
  When I run it with the spec command --format nested
  Then the stdout should match "expected :foo with (\"first\") but received it with ([\"second\"], [\"third\"])"
