And
a file named "flow_mod_controller.rb" with:
class FlowModController < Trema::Controller
  def switch_ready(datapath_id)
    send_flow_mod_add(datapath_id, match: Match.new)
  end
end

Scenarios
  • @sudo
dump_flows (no flow entries)
Given
I trema run "noop_controller.rb" with the configuration "trema.conf"
When
I successfully run trema dump_flows of_switch
Then
the output from "trema dump_flows of_switch" should contain exactly ""
  • @sudo
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 of_switch
Then
the output should match:
^cookie=0x0, duration=\d+\.\d+s, table=0, n_packets=0, n_bytes=0, idle_age=\d+, priority=0 actions=drop
  • @sudo
dump_flows OpenFlow 1.3 (no flow entries)
Given
I use OpenFlow 1.3
And
I trema run "noop_controller.rb" with the configuration "trema.conf"
