Feature: Manage companies In order to keep track of companies A user Should be able to manage companies

Scenario: Create a new company Given I am logged in When I create a new company named Acme Then I should see that a company named Acme exists

features/companies.featuresteps/company_steps.rb

Given "I am logged in" douser = Factory(:user)visits new_session_pathfills_in ‘Login’, :with => user.loginfills_in ‘Password’, :with => user.passwordclicks_button ‘Login’

end

Given == Setup

Given "I am logged in" douser = Factory(:user)visits new_session_pathfills_in ‘Login’, :with => user.loginfills_in ‘Password’, :with => user.passwordclicks_button ‘Login’

end

factory_girl

Factory.sequence(:email) {|n| "user#{n}@example.com" }Factory.define :user do |user| user.name 'User' user.email { Factory.next(:email) }user.login {|u| u.email }
