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

             Summary: Make `SerializerTestBase::getTestData` return List<T>
                 Key: FLINK-20297
                 URL: https://issues.apache.org/jira/browse/FLINK-20297
             Project: Flink
          Issue Type: Improvement
          Components: API / Type Serialization System
            Reporter: Guowei Ma


Currently `SerializerTestBase::getTestData` return T[], which can not be 
override by the Scala. It means that developer could not add scala serializer 
test based on `SerializerTestBase`

So I would propose to change the `SerializerTestBase::getTestData` to return 
List<T>
