Description

The ddm tests have an intermittent failure that occurs randomly. I believe this is a race condition between the Dendrite SMF service being completely ready (e.g. the SMF service reports up but dpd is not able to handle requests yet) in a switch zone and ddm's attempt to use the dpd API. We have a statically defined wait period in the test code - but this likely needs to be made more robust.

Research direction

Start with the ddm tests and locate the statically defined wait period used before the Dendrite SMF service and dpd API are accessed. Reproduce the intermittent failure if possible, then trace the switch-zone readiness path. Done means the tests reliably wait for dpd to handle requests and pass repeatedly without the race.
