--------------------------------------
Summary: Add MockProcessorContext to public test-utils
Key: KAFKA-6473
URL: https://issues.apache.org/jira/browse/KAFKA-6473
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 1.1.0
Reporter: Matthias J. Sax
With KIP-247, we added public test-utils artifact with a TopologyTestDriver
class. Using the test driver for a single
Processor/Transformer/ValueTransformer it's required to specify a whole
topology with source and sink and plus the
Processor/Transformer/ValueTransformer into it.
For unit testing, it might be more convenient to have a MockProcessorContext,
that can be used to test the Processor/Transformer/ValueTransformer in
isolation. Ie, the test itself creates new
Processor/Transformer/ValueTransformer object and calls init() manually passing
in the MockProcessorContext.
This is a public API change and requires a KIP:
