#Welcome to the Seat Reservation System 2000

This is a revolutionary command line tool to reserve seats in a train. The service is already provided and you need to refactor the tests.

To run it you need Ruby >= 1.8 and rspec installed.

When you have Ruby installed, to install RSpec run:

 gem install rspec

or, depending on your system,

 sudo gem install rspec

To run the tests run

rspec

if everything is installed correctly, you get

###How the application works

This app implements the following two user stories:

As a passenger, I want to reserve seats on the train so that I can sit with my homies. And of course I want to know the number(s) of the seat(s) I reserved, duh.

As a Deutsche Bahn personnel, I want to get a list of the seats that are reserved so that I can mark them in the carraige with a little 'X' so that those freeloaders who don't pay to reserve seats don't stop me from making my millions.

You can not actually execute this application, because we want you to focus o n the tests. To see examples how it should work, look at the tests!

How your tests should look like

We always follow the following pattern in structuring our tests, because this way they are easy to maintain, to extend and to read (in case of failure). It is inspired by betterspecs.org

describe Class do
	let(:service) { Service.new}
	let(:data) { "data" }

	before do
		#setup
	end

	describe "#method" do
		subject { service.method }

		it "returns nil" do # the default case
			subject.should be_nil
		end

		context "some context is given" do
			before do
				#setup context
			end

			it "returns 2" do
				subject.should == 2
			end

			it ...
		end

		context ...
	end

	describe ...
end

###The challenge

First improve reservation_service_spec.rb using RSpec. Start with list_reservations and then refactor the tests for reserve. To see how you should structure it, check file_store_spec.rb.

Then refactor store_spec.rb. It is a test/unit test, so you have to port it to RSpec first. You will need mocking and there is sample code for the necessary mocking in the comments.
