Feature: Content Type: Opportunity
  As an author
  I want to publish opportunities
  so that a site visitor can find opportunities and apply.

  @api @javascript
  Scenario: Create a Opportunity node
    Given I am logged in as a user with the "administrator" role
    When I visit "/node/add/opportunity"
    Then I should see the heading "Create Opportunity"
    And I fill in the following:
      | Title | Barista  |
      | City  | Portland |
      | State             | OR    |
      | Job Description    | Make coffee for a city that loves coffee! |
      | URL | http://starbucks.com                     |
    And I create the following "More info" field collections
      | Title | More information |
      | Pay   | Minimal           |
      | Requirements | Ability to put up with uncaffienated and overcaffienated people |
    And I press "Save"
    Then I should see "Barista"
    And I should see "Portland"
    And I should see "OR"
    And I should see "Make coffee for a city that loves coffee!"
    And the link "Apply" should go to "http://starbucks.com"
    And I should see "Pay"
    And I should see "Minimal"
    And I should see "Requirements"
    And I should see "Ability to put up with uncaffienated and overcaffienated people"
