Feature: Flight Emissions Calculations
  The flight model should generate correct emission calculations

  Scenario: Calculations from default
    Given a flight has nothing
    When emissions are calculated
    Then the emission value should be within "0.1" kgs of "42.5"

  Scenario Outline: Calculations from date
    Given a flight has "date" of "<date>"
    When emissions are calculated
    Then the emission value should be within "0.1" kgs of "<emission>"
    Examples:
      | date       | emission |
      | 2009-06-25 | 0.0      |
      | 2010-06-25 | 42.5     |
      | 2011-06-25 | 0.0      |

  Scenario Outline: Calculations from date and timeframe
    Given a flight has "date" of "<date>"
    And it has "timeframe" of "<timeframe>"
    When emissions are calculated
    Then the emission value should be within "0.1" kgs of "<emission>"
    Examples:
      | date       | timeframe             | emission |
      | 2009-06-25 | 2009-01-01/2009-01-31 | 0        |
      | 2009-06-25 | 2009-01-01/2009-12-31 | 42.5     |
      | 2009-06-25 | 2009-12-01/2009-12-31 | 0        |

  Scenario: Calculations from trips
    Given a flight has "trips" of "2"
    When emissions are calculated
    Then the emission value should be within "0.1" kgs of "43.8"
