Assert.fail()和Assert.assertFalse()

Query模块Test Case，有一系列的异常测试，选取其中之一，进行分析，主要是Assert类的用法，代码如下：

这段代码主要是：使用getQueryData方法时，对参数id进行检查(假如是无效或非法的id，则会抛出异常信息)

	@Test
	public void queryWithInvalidID() {		
		log.info("Enter GetQueryDataTest queryWithInvalidID()");
		
		try {	
			log.info("Try to getQueryData");
			dcmAPI.getQueryData(-1,  QueryType.AVG_PWR, AggregationLevel.SELF, startTime,
					oneCycleEndTime, FREQUENCY);
			log.info("getQueryData finished");
			Assert.fail("Should get exception here!");
		} catch (Exception e) {
			Assert.assertFalse("Should not get exception "
					+ e.getClass().getSimpleName() + ": " + e.getMessage(),
					Utilities.isNotExceptedException(e,
							"DcmIllegalIdException", null));
		}
		
		log.info("Exit GetQueryDataTest queryWithInvalidID()");
	}
