Feature: Purchase Emissions Calculations
  The purchase model should generate correct emission calculations

  Scenario: Calculations starting from nothing
    Given a purchase has nothing
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "120694.715"

  Scenario: Calculations starting from purchase amount
    Given a purchase has "purchase_amount" of "107.11"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "120694.715"

  Scenario: Calculations starting from date
    Given a purchase has "date" of "2010-07-28"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "120694.715"

  Scenario Outline: Calculations starting from a merchant
    Given a purchase has "merchant.id" of "<id>"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "<emission>"
    Examples:
      | id  | emission  |
      | 1   | 120694.715|
      | 2   | 110152.836|

      | 4   | 115090.859|
      | 5   | 110346.441|

  Scenario Outline: Calculations starting from a merchant with purchase amount
    Given a purchase has "merchant.id" of "<id>"
    And it has "purchase_amount" of "<amount>"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "<emission>"
    Examples:
      | id  | amount | emission  |
      | 1   | 107.11 | 120694.715|
      | 2   | 107.11 | 110152.836|

      | 5   | 107.11 | 110346.441|
  
  Scenario Outline: Calculations starting from a merchant with purchase amount and date
    Given a purchase has "merchant.id" of "<id>"
    And it has "purchase_amount" of "<amount>"
    And it has "date" of "<date>"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "<emission>"

  Scenario Outline: Calculations starting from a merchant with purchase amount, date, and tax
    Given a purchase has "merchant.id" of "<id>"
    And it has "purchase_amount" of "<amount>"
    And it has "tax" of "<tax>"
    And it has "date" of "<date>"
    When emissions are calculated
    Then the emission value should be within "0.001" kgs of "<emission>"
