Feature: Manage Articles
  In order to make a blog
As an author
I want to create and manage articles

Scenario: Articles List
Given I have articles titled Pizza, Breadsticks
  When I go to the list of articles
  Then I should see "Pizza"
  And I should see "Breadsticks"

Scenario: Create Valid Article
Given I have no articles
  And I am on the list of articles
  When I follow "New Article"
  And I fill in "Title" with "Spuds"
  And I fill in "Content" with "Delicious potato wedges!"
  And I press "Create"
  Then I should see "New article created."
  And I should see "Spuds"
  And I should see "Delicious potato wedges!"
  And I should have 1 article
