Feature: Send echo request and receive echo reply messages

  In order to hear heart beats from openflow switches
  As a Trema user
  I want to send echo request messages to openflow switches and receive echo replies

  @slow_process
  Scenario: Echo request and reply in C
    Given a file named "echo.conf" with:
      """
      custom_switch("echo") { 
        datapath_id "0xabc"

      }
      """
    When I run `trema run "../../objects/examples/openflow_message/echo 10" -c echo.conf -d`
      And wait until "echo" is up
      And I run `trema killall`
    Then the file "../../tmp/log/customswitch.echo.log" should contain:
      """
