Feature: Protocol version negotiation
  In order to handle connecting to different Stomp protocol implementations
  As a client
  I want to be able to negotiate the Stomp protocol to use
  
  Scenario: By default, allow 1.1 from broker
    Given a Stomp 1.1 broker
    When a connection is established
    Then the connection should be using the 1.1 protocol
    
  Scenario: By default, allow 1.0 from broker
    Given a Stomp 1.0 broker
    When a connection is established
    Then the connection should be using the 1.0 protocol
    
  Scenario: By default, assume 1.0 from version-less broker
    Given an unversioned Stomp broker
    When a connection is established
    Then the connection should be using the 1.0 protocol
  
  Scenario: By default, raise error if the broker's version isn't supported
    Given a Stomp 2.1 broker
    When a connection is created from the broker's URI
    Then connecting should raise an unsupported protocol version error
  
  Scenario: A 1.0 client should accept a 1.0 broker
    Given a Stomp 1.0 broker
    When the client protocol version is "1.0"
    And a connection is established
    Then the connection should be using the 1.0 protocol
  
  Scenario: A 1.0 client should accept a version-less broker
    Given an unversioned Stomp broker
    When the client protocol version is "1.0"
    And a connection is established
    Then the connection should be using the 1.0 protocol
    
  Scenario: A 1.0 client should not accept a 1.1 broker
    Given a Stomp 1.1 broker
    When the client protocol version is "1.0"
    And a connection is created from the broker's URI
    Then connecting should raise an unsupported protocol version error
    
  Scenario: A 1.1 client should accept a 1.1 broker
    Given a Stomp 1.1 broker
    When the client protocol version is "1.1"
    And a connection is established
    Then the connection should be using the 1.1 protocol
  
  Scenario: A 1.1 client should not accept a 1.0 broker
    Given a Stomp 1.0 broker
    When the client protocol version is "1.1"
    And a connection is created from the broker's URI
    Then connecting should raise an unsupported protocol version error

  Scenario: A 1.1 client should not accept a version-less broker
    Given an unversioned Stomp broker
    When the client protocol version is "1.1"
    And a connection is created from the broker's URI
    Then connecting should raise an unsupported protocol version error
