Feature: Insert new routes in Kapow! server.
  Inserting routes allows users to configure the server. New
  routes could be inserted at the beginning or before any
  existing route of the routes list.

  Background:
    Given I have a Kapow! server with the following routes:
      | method | url_pattern    | entrypoint | command                                          |
      | GET    | /foo           | /bin/sh -c | ls -la / \| kapow set /response/body                       |
      | GET    | /qux/{dirname} | /bin/sh -c | ls -la /request/params/dirname \| kapow set /response/body |

  Scenario: Insert a route at the beginning.
    A route can be inserted at the beginning of the list
    by specifying an index 0 in the request.

    When I insert the route:
      """
      {
        "method": "GET",
        "url_pattern": "/bar",
        "entrypoint": "/bin/sh -c",
        "command": "ls -la /var | kapow set /response/body",
        "index": 0
      }
      """
    Then I get 201 as response code
      And I get "Created" as response reason phrase
      And I get the following response body:
        """
        {
          "method": "GET",
          "url_pattern": "/bar",
          "entrypoint": "/bin/sh -c",
          "command": "ls -la /var | kapow set /response/body",
          "index": 0,
          "id": ANY
        }
        """

  Scenario: Insert a route in the middle.
    A route can be inserted in the middle of the list
    by specifying an index less or equal to the last
    index in the request.

    When I insert the route:
      """
      {
        "method": "GET",
        "url_pattern": "/bar",
        "entrypoint": "/bin/sh -c",
        "command": "ls -la /var | kapow set /response/body",
        "index": 1
      }
      """
    Then I get 201 as response code
      And I get "Created" as response reason phrase
      And I get the following response body:
        """
        {
          "method": "GET",
          "url_pattern": "/bar",
          "entrypoint": "/bin/sh -c",
          "command": "ls -la /var | kapow set /response/body",
          "index": 1,
          "id": ANY
        }
        """
