Gherkin — Checkout Feature (Background, Outline, Doc String)

# language: en
@checkout @smoke
Feature: Checkout totals
  As a shopper
  I want the cart total to include tax and discounts
  So that I am never surprised at the payment step

  Background:
    Given the catalogue contains:
      | sku     | name             | price |
      | NX-1042 | Sample desk lamp | 12.99 |
      | NX-2087 | Sample notebook  |  4.50 |
    And the tax rate is 20 percent

  @pricing
  Scenario: A single-item cart shows tax separately
    Given my cart is empty
    When I add 1 of "NX-1042"
    Then the subtotal is "12.99"
    And the tax is "2.60"
    And the total is "15.59"

  @pricing @outline
  Scenario Outline: Quantity multiplies the subtotal
    Given my cart is empty
    When I add <quantity> of "<sku>"
    Then the subtotal is "<subtotal>"

    Examples: whole units
      | sku     | quantity | subtotal |
      | NX-1042 |        1 |    12.99 |
      | NX-1042 |        3 |    38.97 |
      | NX-2087 |        2 |     9.00 |

    @edge
    Examples: boundary quantities
      | sku     | quantity | subtotal |
      | NX-1042 |        0 |     0.00 |

  @receipt
  Scenario: The receipt renders as plain text
    Given my cart contains 1 of "NX-1042"
    When I request the receipt
    Then the receipt reads:
      """
