Feature: Support content_for and yield_content helpers
    
  Scenario: content_for works as expected in haml
    Given the Server is running at "content-for-app"
    When I go to "/content_for_haml.html"
    Then I should see "In Layout: I am the yielded content haml"
    
  Scenario: content_for works as expected in slim
    Given the Server is running at "content-for-app"
    When I go to "/content_for_slim.html"
    Then I should see "In Layout: I am the yielded content slim"
