Intro to testing using RSpec for 1-UP workshop

warehouse.rb

require 'rspec/autorun'

class WareHouse
  attr_reader :quantity

  def initialize
    @quantity = 0
  end

end

# RSpec 

describe "Warehouse inventory" do
  subject {WareHouse.new}

  it "should start empty" do
    expect(subject.quantity).to eq(0)
  end

  it "should have a quantity of 1 after adding an item" do
    subject.add_item
    expect(subject.quantity).to eq(1)
  end
end

a worked example to read through or follow along trying it out
http://code.tutsplus.com/tutorials/ruby-for-newbies-testing-with-rspec--net-21297

some common matchers for you to play with

expect(subject).to be_true
expect(subject).to be_false
expect([]).to be_empty
expect({:foo => :bar}).to include(:foo => :bar)

primes = [1,2,3,5,7]
expect(primes).not_to include(4)

expect("Some string").to eq("Some string")
expect("Some string").not_to match(/foobar/)

# Message expectations. The expectation needs to be set up *before* the message is received
object = Object.new
expect(object).to receive(:do_stuff)
object.do_stuff
