The main goal of the functionality test is to verify if the ONOS package is working correctly. Functionality test focuses on testing the intent framework which allows us to build different scenarios in the network topology that ONOS should be able to handle. A test run covers from network discovery to rerouting flows by changing the network topology during the test. We verify the results by analyzing ONOS state before and after each scenarios as well as confirming hosts reachability.
