1、二是用来辅助测试使用的数据2012年09月03日|作者: songhoubo|分类: 办公软件|系列原创：性能测试新手误区测试环境的重要性无需多说，大家都知道测试环境要尽量的模拟生产环境，当然也包括数据。这样测试的结果才会更加准确的反应真实的性能。就连开发过程，都已经开始在大数据量下加压开发了。那么，关于测试数据，你了解多少呢？通常说的测试数据可以分为两类：一是为了测试性能而准备的数据，这是用来模拟“压力”的数据。也就是常说的数据量、历史数据等。 中。那么我们要测这个打分的操作，首先就要保证有可用的案件，这就需要去生成测试数据，该数据可能一经使用就失效了（已经打过分就不能再打了）。这样，每 次
2、测试这个功能，就需要准备这样一批数据。这里的测试数据，更多的是和测试流程有关，是为了能够正常的进行测试，而不是涉及到性能的。我们这里要说的是第一类，对性能测试结果产生直接影响的数据。先看两个小案例，涉及到了案件表（T_AJ）和法院编号列（N_FY）、立案日期列（D_LARQ）。案件表中模拟了一百万测试数据，测试简单的查询操作，根据经验，预期响应时间在2秒之内。案例1. 查询本院案件列表，相应的SQL如下：经排查，生成的100W测试数据中，所有的N_FY列值都为10。这样，最明显的问题就是，查询的结果集数量完全偏离了正常范围。如果实际有 100家法院，正常分布下，每家法院只有1W的案件，但测试数
3、据的FY只有一个值，通过这个查询，查出了原来100家法院的数据。无论是在数据库处理中 （如本例的排序），还是在程序的处理中（如展现或者是对数据做进一步处理），两者的性能差异都是很显著的。所以这个测试结果是无效的。有人说，这个例子太弱了，结果集差了100倍，性能当然不一样了。那是不是数据总量和结果集大小都一致，测试结果就是有效了呢？案例2.查询本院一个月内收的案件，相应SQL如下：7款秋季美味鱼减肥食谱2012年08月24日|作者: songhoubo|分类: 健康资讯|7款秋季美味的鱼的饮食你也想苗条的美丽的秋天，美丽的季节可以达到美丽的爱情。到了秋天，减肥计划不能懈怠放松。告诉你属于的重量美
