----------------------------------

             Summary: Add support for multiple output fields to FixedTupleSpout
                 Key: STORM-2791
                 URL: https://issues.apache.org/jira/browse/STORM-2791
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
            Reporter: Daniel Dara
            Priority: Minor


The class [FixedTupleSpout https://github.com/apache/storm/blob/64e29f365c9b5d3e15b33f33ab64e200345333e4/storm-client/src/jvm/org/apache/storm/testing/FixedTupleSpout.java#L34] is useful for emitting test tuples in end-to-end topology tests. Unfortunately it appears to only support a single output field, which greatly limits what topologies you can test with.

I propose adding a new constructor to FixedTupleSpout to allow specifying more than one field.

PR is forthcoming.
