    And a file named "flow_mod_controller.rb" with:

  Scenario: dump_flows (no flow entries)
    Given I trema run "noop_controller.rb" with the configuration "trema.conf"
    When I successfully run `trema dump_flows 0xabc`
    Then the output from "trema dump_flows 0xabc" should not contain "actions=drop"

  @sudo
  Scenario: dump_flows (one flow entry)
    Given I trema run "flow_mod_controller.rb" with the configuration "trema.conf"
    When I successfully run `trema dump_flows 0xabc`
    Then the output from "trema dump_flows 0xabc" should contain "actions=drop"
