public class BoltInstanceTest
extends java.lang.Object
To test the Bolt's ReadTupleAndExecute() method, it will:
1. We will instantiate a slave with TestBolt's instance.
2. Construct a bunch of mock Tuples as protobuf Message to be consumed by the TestBolt
3. Offer those protobuf Message into inStreamQueue.
4. The TestBolt should consume the Tuples, and behave as described in its comments.
5. Check the values in singleton registry: execute-count, ack-count, fail-count, received-string-list.
6. We will also check some common values, for instance, the stream name.
