It does not seem to be possible to provide a TypeInformation for side outputs to a TestHarness. This sounds like a useful addition. Would you mind creating a Jira issue for that? Thank you, Fabian Am So., 3. Feb. 2019 um 19:13 Uhr schrieb Alexey Trenikhun <yen...@msn.com<mailto:yen...@msn.com>>: TestHarness has setup(TypeSerializer outputSerializer) method, which allows to set serializer for primary output. Still unclear how to set side output serializers for MockOutput.

However in test when I'm trying to use KeyedTwoInputStreamOperatorTestHarness I can't find way to set output type via explicit TypeInformation, furthermore if I'm trying to use side output, public <X> void AbstractStreamOperatorTestHarness::collect(OutputTag<X> outputTag, StreamRecord<X> record) seems ignore type information in outputTag and instead tries to extract type information from value using TypeExtractor.getForObject(record.getValue()). Is it expected behavior? Is another way specify type information for test harness? Thanks, Alexey
