JMeter学习-014-JMeter 配置元件实例之 - 用户定义的变量 参数化配置

前文讲述了通过 CSV Data Set Config 实现参数化配置（详情敬请参阅：JMeter学习-010-JMeter 配置元件实例之 - CSV Data Set Config 参数化配置），在 JMeter 的配置元件中还有一个元件：用户定义的变量，通过 用户定义的变量，也可实现参数化的配置，通常用户定义的变量一般作为全局变量使用。下面就以 用户定义的变量 替换之前博文中的配置文件实现单一循环的参数化配置。

 

用户定义的变量添加路径：【 添加 / 配置元件 / 用户定义的变量 】，其对应的配置页面如下所示：

配置参数说明：

名称：对用户定义变量的简述

注释：对用户定义变量的详细概述

名称：定义变量的引用名称

值：变量的值

描述：对定义变量的描述信息

 

参数化脚本修改方法：

第一步：删除原 配置元件/CSV Data Set Config 参数文件

第二步：通过 【 添加 / 配置元件 / 用户定义的变量 】添加用户定义的变量组件

第三步：配置用户定义的变量

将之前 CSV Data Set Config 参数文件中配置的变量配置到添加的组件 用户定义的变量中，配置好的用户定义的变量如下所示：

第四步：执行脚本

脚本执行结果如下图所示：

由上图我们可以看到，实际脚本中配置了两个用户定义的变量组件（分别为不同的商品，且变量中的名称均相同），从执行结果我们可以看出，当变量名称相同时，脚本优先引用最近的可使用的变量。若在日后的脚本编写调试过程中，发现变量的值不是期望的值，除了获取变量获取错误或配置错误之外，还存在一种可能就是就近变量覆盖。
