JMeter笔记11 | JMeter事务

1 事务

• 性能测试比较关注TPS，而TPS代表每秒事务数；
• 每个事务对应的是每个请求；
• JMeter把每个请求统计成一个事务；
• JMeter也可以把多个操作统计成一个事务，可通过逻辑控制器中的事务控制器来完成。

2 逻辑控制器

• 逻辑控制器从字面理解就是控制程序的逻辑；
• JMeter逻辑控制器有很多个，本文主要用到的是事务控制器；
• JMeter逻辑控制器如下：

3 事务控制器

3.1 参数说明

4 实例说明

• 在JMeter笔记10 | JMeter检查点基础上我们添加事务控制器；
• 控制器添加在线程组下。

4.1 添加【事务控制器】

• 在线程组“禅道接口”下添加事务控制器，如下：

• 直接运行脚本，发现“查看结果树”中没有事务控制器的显示
  

4.2 勾选Generate parent sample

• 勾选Generate parent sample，运行脚本，发现“查看结果树”中有事务控制器的显示；
  
• 从上图中为什么事务控制器是成功的，因为它下边没有任何取样器。

4.3 在事务控制器下添加取样器

• 我们把之前脚本中的“1-获取token”和“1-1-获取用户列表”拖放到事务控制器下；
• 运行后发现，事务控制器是成功的，且下边的取样器也可以看到。

• 我们再把“2-创建用户”这个失败的请求放到事务控制器下，再次运行，会发现事务是失败的，那就满足规则“事务控制器下任何一个取样器失败，则整个事务失败”
