Release 1.30.0 - Polling

Support for polling APIs

The polling configuration is automatically reset before each scenario.
It can be configured via the background or directly in the scenario.

When the expected HTTP status code and JSON structure has been sent as a response, polling will stop.
This allows an endpoint to be polled until it changes state or fail if the state has not changed during the specified time and retry configuration.

The configuration can be done in to ways.

As a single line configuration:

Scenario: Single line configuration
    Given that a request polls every 1 seconds for 5 times

Or as a multiline configuration that supports to specify one of the configurations in the Background and the other in the Scenario (or to have it more readable).

Scenario: Multiline configuration
    Given that a requests polls every 1 seconds
    And that a requests polls for 5 times

The URL/URI and (if required) body have to be preconfigured. Polling itself does simply use previous set body and path definition.
To execute a request it supports the well known authorized and unauthorized phrases and it supports direct JSON or JSON from file:

Authorized request with JSON response file:

Scenario: Authorized request with JSON response file
  Given that a request polls every 1 seconds for 5 times
  And that the API path is "/api/v1/polling"
  When executing an authorized GET poll request until the response code is 200 and the body is equal to file "expected.json"

Unauthorized request with JSON response file:

Scenario: Unauthorized request with JSON response file
  Given that a request polls every 1 seconds for 5 times
  And that the API path is "/api/v1/polling"
  When executing a GET poll request until the response code is 200 and the body is equal to file "expected.json"

Authorized request with direct JSON response:

Scenario: Authorized request with JSON response file
  Given that a request polls every 1 seconds for 5 times
  And that the API path is "/api/v1/polling"
  When executing an authorized GET poll request until the response code is 200 and the body is equal to
    """
    {
      "message": "SUCCESSFUL"
    }
    """

Unauthorized request with direct JSON response:

Scenario: Unauthorized request with JSON response file
  Given that a request polls every 1 seconds for 5 times
  And that the API path is "/api/v1/polling"
  When executing a GET poll request until the response code is 200 and the body is equal to
    """
    {
      "message": "SUCCESSFUL"
    }
    """
