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”
