Add basic, and failing, unit tests for RelationFetchOperation.fromResponse()
Use JsonNode.path(String) which returns MissingNode instead of null
to eliminate two NPE's. Makes RelationFetchOperationTest.jsonIsEmpty
pass.
Extract JSON parsing from RelationFetchOperation.fromResponse() to
parry JsonMappingException.
Makes RelationFetchOperationTest.jsonIsIsBlank pass.
Refactor RelationFetchOperation.parseJson to handle null.
Makes RelationFetchOperationTest.jsonIsNull pass.
