RSPEC PHILOSOPHY:

RSPEC PHILOSOPHY: All tests / examples are completely isolated and independent!

RSPEC PHILOSOPHY: All tests / examples are completely isolated and independent! This is a problem forintegration testing / stories.

OPTION 1: Long examplesit “very long user story” do # Log In visit login_path fill_in :login, “quentin” click “Log In” page.should have_text(“Welcome, Quentin!”) # Update Profile click “Update Profile” page.should have_css(“form#edit_account”) # More shit ... another 100 lines & 20 requests ...end

OPTION 2: Repeat Yourselfit “should log in” do visit login_path fill_in :login, “quentin” click “Log In” page.should have_text(“Welcome, Quentin!”)endit “should log in and load profile form” do visit login_path ... etc ... click “Update Profile” page.should have_css(“form#edit_account”)endit “should log in AND load form AND update profile” doend

OPTION 3: Cucumber!

INTRODUCING: RSpec-Steps steps “neat user story” do it “should log in” do visit login_path fill_in :login, “quentin” click “Log In” page.should have_text(“Welcome, Quentin!”) end it “should load profile form do” click “Update Profile” page.should have_css(“form#edit_account”) end it “etc ... more steps” do end end

Using RSpec-Steps# Gemfilegem ‘rspec-steps’

NEXT PROBLEM: Database Transactionsrequire ‘capybara’it “should log in”, :type => :request do user = Factory(:user) visit login_path fill_in :name, user.name click “Login”end

Won’t Work!Factor y() and request are in different transactions!

SOLUTION: DatabaseCleaner# Gemfilegem ‘database-cleaner’

SOLUTION: DatabaseCleaner# spec_helper.rbconfig.use_transactional_fixtures = :falseconfig.after :all, :type => :request do DatabaseCleaner.clean_with :truncation load db/seeds.rbend
