Example 1 with FieldMapper

use of org.opensearch.index.mapper.FieldMapper in project OpenSearch by opensearch-project.

the class AggregatorTestCase method testSupportedFieldTypes.

/**
 * This test will validate that an aggregator succeeds or fails to run against all the field types
 * that are registered in {@link IndicesModule} (e.g. all the core field types).  An aggregator
 * is provided by the implementor class, and it is executed against each field type in turn.  If
 * an exception is thrown when the field is supported, that will fail the test.  Similarly, if
 * an exception _is not_ thrown when a field is unsupported, that will also fail the test.
 *
 * Exception types/messages are not currently checked, just presence/absence of an exception.
