Review Comment: `validatePagination` from `SearchElasticsearchTest` as is will not work for `PaginatedJsonQueryElasticsearchTest` as there are differences in the call to `AbstractJsonQueryElasticsearchTest.testCounts` in the `validatePagination` of `SearchElasticsearchTest` and `PaginatedJsonQueryElasticsearchTest` In addition when looking at the `assertState` of `SearchElasticsearchTest` the assertions for `PaginationType` require a state which `PaginatedJsonQueryElasticsearchTest` which as you mentioned is not set, so why would there be a need to test anything with the `PaginationType` in `PaginatedJsonQueryElasticsearchTest`? -- This is an automated message from the Apache Git Service.
