### Question:
ApiOperations { public static ApiOperation deleteQueueItems(String queueName) { return new DeleteQueueItems(queueName); } private  ApiOperations(); static ApiOperation deleteItem(String id); static ApiOperation deleteItem(String id, byte[] version, RequestMode requestMode); static ApiOperation deleteQueueItems(String queueName); static ApiOperation batch(Iterator<ApiOperation> operations);  }### Answer:
@Test public void deleteQueueItems_helpers() { DeleteQueueItems deleteQueueItems = (DeleteQueueItems) ApiOperations.deleteQueueItems("queueName"); assertThat(deleteQueueItems.getQueueName(), equalTo("queueName")); assertThat(deleteQueueItems.toString(), equalTo("DeleteQueueItems [queueName=queueName]")); }
