##Testing Battle Plan For Phase 2

###Types of Tests

• Unit Tests (model) : small and atomic - test the interface of a class. ie Dog.speak() == "woof"
• Function Testing (controller)

describe ContactsController do
  describe "GET #index" do
    it "populates an array of contacts"
    it "renders the :index view" end

• Integration Test : Issue http requests to test the flow of data from the client to the server. Expensive and slow.
• Acceptance Testing : Does the application meet pre-defined business rules / logic

###What technology?

• Rspec = DSL for testing in Ruby. Has more englishy terms (looks more like Ruby)
• Rack::Test - API for testing Rack based frameworks (like Sinatra)
• Shoulda Matchers - library for faster model tests
• Factory Girl - library to create resources for tests
• Capybara - integration testing

###A simple sample

###Testing in Sinatra

• Run the sample app:
  • bundle
  • rake db:create
  • rake db:migrate
  • rake db:test:prepare - create a test database
  • rake run the default rake task which is spec or rake spec
  • You should see passing tests.
  • Look in the spec directory to see these test and write some of your on.

Write Tests

• No really, write some tests!
