Dawid Wysakowicz commented on FLINK-20297:
------------------------------------------
Can you elaborate why it is not possible to override said method? As far as I
know it should be possible. We even do that already e.g. in
{{ScalaCaseClassSerializerTest}}.
> Make `SerializerTestBase::getTestData` return List<T>

> 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>
