Proposed Changes
Addition ofPhase 1:

---|
public final Set<String> getOutputTopicNames() { return Collections.unmodifiableSet(outputRecordsByTopic.keySet()); } |
Phase 2:
The implementation will be changed such that the key set of outputRecordsByTopic is initialized with all known output, i.e. internal and sink, topic names upon construction of the TopologyTestDriver from the TopologyDescription. This second phase will mean getOutputTopicNames() will return most topic names even before any input is piped through the topology. Topics that use a non-static TopicNameExtractor will not be populated on construction.
