[trema]/src/examples/topology/listener.rb is a simple usage example of
topology Ruby API.

listener.rb shows a typical use case of topology Ruby API.

Obtain the initial state of the topology by get_all_{switch,link.port} and build the initial datastructure.
Keep local datastructure updated by topology event handlers.

Note:

This controller includes Topology module, which implicitly starts topology manager, if it not already running.
This controller defines link_state_updated handler, which implicitly enables the topolgy manager's link discovery feature.

Scenarios

Scenario

When

I successfully run trema run ./listener.rb -c topology_fullmesh.conf -d

And

wait until "topology" is up

And

*** sleep 10 ***

Then

the file "../../../tmp/log/TopologyListener.log" should match /graph "\d\d\d\d-\d\d-\d\dT\d\d:\d\d:\d\d" \{/

Then

the file "../../../tmp/log/TopologyListener.log" should match / "0xe1"$/

Then

the file "../../../tmp/log/TopologyListener.log" should match / "0xe2"$/

Then

the file "../../../tmp/log/TopologyListener.log" should match / "0xe3"$/

Then

the file "../../../tmp/log/TopologyListener.log" should match / "0xe0"$/
