------------------------------------
Summary: Add utils for serialization compatibility tests
Key: FLINK-11753
URL: https://issues.apache.org/jira/browse/FLINK-11753
Project: Flink
Issue Type: Improvement
Reporter: Igal Shilman
Assignee: Igal Shilman
It would be helpful to have few hamcrest matchers, and stub-serializer/snapshot
classes to ease
unit testing serializer schema related logic.
This is currently implemented in few different places already, in different
ways.
For example:
*
[https://github.com/apache/flink/blob/master/flink-formats/flink-avro/src/test/java/org/apache/flink/formats/avro/typeutils/AvroSerializerSnapshotTest.java#L192]
*
[https://github.com/apache/flink/blob/master/flink-core/src/test/java/org/apache/flink/api/common/typeutils/base/EnumSerializerSnapshotMigrationTest.java#L74]
*
[https://github.com/apache/flink/blob/1850193b956b899aefd3ea84fe726e10b9359b55/flink-core/src/test/java/org/apache/flink/api/common/typeutils/TypeSerializerSnapshotMigrationTestBase.java#L533]
A stub serializer, is a serializer that returns a stub snapshot, which can be
configured during test setup how to behave when
restoreSerializer/resolveSchemaCompatibility are called.
This would be very useful for tests that test composite serializers.
