Disabled in https://git.opendaylight.org/gerrit/70715 for now. k.faseela are you motivated to assign this to yourself, locally re-remove that Ignore, and using the RunUntilFailureRule see if we can figure out what's causing this? (NB that even if it does always pass locally with the RunUntilFailureRule, there could still be a problem - it may just only happen on slow build VMs, but still always pass locally; but doing that simple reproducing test is at least a first step...)
https://git.opendaylight.org/gerrit/#/c/67468/ has migrated to AbstractListenerBaseClass which does not support awaitEventsConsumption(). I am not sure whether that is impacting the tests, as this listener is an important part of interface-manager tests.
Now anyways that we are going to ignore this, all patches can be merged without worrying about all these 
And one fine day, when I enable it back, I have to fix all these.
This change made the new listeners testable, so I think we could re-enable the test again.
This has made my day dsuarezf 
I think let us try to re-enable the tests and see how it goes.
I have been trying to run this locally with RunUntilFailure, but couldn't get the tests to fail, and it is passing.
