### Question:
DataTypeHandler { public void init(final ItemDefinitionRecordEngine recordEngine) { this.recordEngine = recordEngine; } DataTypeHandler(final DataTypeStore dataTypeStore,
                    final DataTypeManager dataTypeManager); void init(final ItemDefinitionRecordEngine recordEngine);  }### Answer:
@Test public void testInit() { final ItemDefinitionRecordEngine expectedRecordEngine = mock(ItemDefinitionRecordEngine.class); handler.init(expectedRecordEngine); final ItemDefinitionRecordEngine actualRecordEngine = handler.getRecordEngine(); assertEquals(expectedRecordEngine, actualRecordEngine); }
