Yishun Guan edited comment on KAFKA-6460 at 1/31/19 11:32 PM: -------------------------------------------------------------- Hi [~guozhang] , I still not quite understand - so we should implement _StoreTestDriver_ class that will be providing _MockStoreSupplier_ and _MockStoreBuilder_ classes? _Or StoreSupplier and StoreBuilder doesn't have to be mock, but this StoreTestDriver_ will contain these two as variables and wrap around those _and provide auxiliary methods (like createKeyValueStore or getSizeOfStore) for testing purpose_? Is a KIP needed? thanks was (Author: shung): Hi [~guozhang] , I still not quite understand - so we should implement _StoreTestDriver_ class that will be providing _MockStoreSupplier_ and _MockStoreBuilder_ classes_?_ Or StoreSupplier and StoreBuilder doesn't have to be mock, but this _StoreTestDriver_ will contain these two as variables and wrap around those __ and provide auxiliary methods (like createKeyValueStore or getSizeOfStore) for testing purpose_?_ Is a KIP needed? thanks > Add mocks for state stores used in Streams unit testing > ------------------------------------------------------- > > Key: KAFKA-6460 > URL: https://issues.apache.org/jira/browse/KAFKA-6460 > Project: Kafka > Issue Type: Improvement > Components: streams, unit tests > Reporter: Guozhang Wang > Assignee: Yishun Guan > Priority: Major > Labels: newbie++ > > We'd like to use mocks for different types of state stores: kv, window, > session that can be used to record the number of expected put / get calls > used in the DSL operator unit testing. This involves implementing the two > interfaces {{StoreSupplier}} and {{StoreBuilder}} that can return a object > created from, say, EasyMock, and the object can then be set up with the > expected calls. > In addition, we should also add a mock record collector which can be returned > from the mock processor context so that with logging enabled store, users can > also validate if the changes have been forwarded to the changelog as well. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
