### Question:
CommonsQueryEngine implements IQueryEngine { protected abstract void pagedExecuteWorkFlow(String queryId, LogicalWorkflow workflow, IResultHandler resultHandler, int pageSize) throws ConnectorException ; protected  CommonsQueryEngine(ConnectionHandler connectionHandler); @Override final void asyncExecute(String queryId, LogicalWorkflow workflow, IResultHandler resultHandler); @Override final void pagedExecute(String queryId, LogicalWorkflow workflow, IResultHandler resultHandler,
                                   int pageSize); @Override final QueryResult execute(String queryId, LogicalWorkflow workflow);  }### Answer:
@Test public void testpagedExecuteWorkFlow() throws Exception { String queryID = "queryID"; LogicalWorkflow logicalworkFlow = mock(LogicalWorkflow.class); IResultHandler resultHandler = mock(IResultHandler.class); commonsQueryEngineStub.pagedExecute(queryID, logicalworkFlow, resultHandler, 10); assertTrue("executeWorkFlow must be executed", pagedExecuteAsyncExecute); assertEquals("The queryId must be correct", queryIdSend, queryID); assertEquals("The workflow must be correct", workflowSend, logicalworkFlow); assertEquals("The resultHandler must be correct", resultHandler, resultHandlerSend); assertEquals("The paged must be correct", pageSizeExecute, 10); }
