【P31】JMeter loop controller (Loop Controller)

---

1. Loop Controller parameter description

可以对部分逻辑按常量进行循环迭代

Right-click on the thread group >>> Add >>> Logic Controller >>> Loop Controller

• Loop Count: Set the number of times to run, Infinite is checked to run forever

2. Test plan design

2.1, set the number of cycles

(1), right click on the test plan <<< add <<< thread (user) <<< thread group

• The parameters are default

(2), right click on the thread group <<< add <<< sampler <<< debug sampler

• Name: Debug Sampler-1

(3), right click on the thread group <<< add <<< logic controller <<< cycle controller

• Number of cycles: 5

(4), right click on the cycle controller <<< add <<< sampler <<< debug sampler

• Name: Debug Sampler-2

(5), right click on thread group <<< add <<< listener <<< view result tree

(6) Click to start, click to view the result tree to view

如图，循环控制器下的 调试取样器-2 执行了5次

2.2, check forever

(1), modify the loop controller, check forever

(2), click to clear all, click to start, click to view the result tree to view

如图，循环控制器下的 调试取样器-2 会一直运行

2.3. Set the duration of the thread group

(1) Modify the thread group, check the scheduler, and set the duration to 3

• Check the scheduler

• Duration (seconds): 3

(2), click to clear all, click to start, click to view the result tree to view

如图，执行3s后，会停止，虽然循环控制器勾选了永远，但是因为线程组设置了持续时间，所以按照线程组的持续时间执行
