----------------------------------------------------------------
Modified description to list it as a possible approach. It wasn't immediately
obvious to me how this could be done similar to the DROP_CALLS abstraction and
hence had not specified it before.

> Implement filtering mechanism for (Scheduler API Events) Testing

> Key: MESOS-3339
> URL: https://issues.apache.org/jira/browse/MESOS-3339
> Project: Mesos
> Issue Type: Task
> Components: test
> Reporter: Anand Mazumdar
>
> Currently, our testing infrastructure does not have a mechanism of
> filtering/dropping HTTP events of a particular type from the Scheduler API
> response stream. We need a {{DROP_HTTP_CALLS}} abstraction that can help us
> to filter a particular event type.
> {code}
> // Enqueues all received events into a libprocess queue.
> ACTION_P(Enqueue, queue)
> {
> std::queue<Event> events = arg0;
> while (!events.empty()) {
> // Note that we currently drop HEARTBEATs because most of these tests
> // are not designed to deal with heartbeats.
> // TODO(vinod): Implement DROP_HTTP_CALLS that can filter heartbeats.
> if (events.front().type() == Event::HEARTBEAT) {
> VLOG(1) << "Ignoring HEARTBEAT event";
> } else {
> queue->put(events.front());
> }
> events.pop();
> }
> }
> {code}
> This helper code is duplicated in at least two places currently, Scheduler
> Library/Maintenance Primitives tests.
> - The solution can be as trivial as moving this helper function to a common
> test-header
> - Implement a decorator reader class over {{RecordIOReader}} having the
> functionality of filtering events.
> - Implement a {{DROP_HTTP_CALLS}} similar to what we do for other protobufs
> via {{DROP_CALLS}}.
