【P36】JMeter Interleave Controller

---

1. Interleave Controller parameter description

可以将内部的组件在线程迭代时交替执行；交替控制器内部一般会有多个取样器

Select the right button of the thread group >>> Add >>> Logic Controller >>> Interleave Controller

• Ignore sub-controller blocks (Ignore sub-controller blocks): The sub-controller function fails and is replaced by an alternate controller

• Interleave across threads: Cross-thread alternation, when the thread group is set to run with multiple threads, each round of the cycle, each thread gets a new request in the alternate controller

2. Test plan design

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

• Number of cycles: 6

• Other parameters can be default

(2), right click on the thread group <<< add <<< sampler <<< JSR223 Sampler

• Name: JSR223 Sampler-1

log.info("JSR223 Sampler-1");

(3), right click on the thread group <<< add <<< sampler <<< JSR223 Sampler

• Name: JSR223 Sampler-2

log.info("JSR223 Sampler-2");

(4) Open the log, click Clear All, click Start, and view the log information

点击菜单选项按钮，点击日志查看，打开日志

如图，每个 JSR223 Sampler 取样器都迭代执行了6次，一共执行了12个取样器

(5) Right click on the thread group <<< Add <<< Logic Controller <<< Alternate Controller, put two JSR223 Samplers under the Alternate Controller

• The parameters are default

(6) Open the log, click Clear All, click Start, and view the log information

如图，每个 JSR223 Sampler 取样器都只迭代执行了3次，一共执行了6个取样器

(7), alternate controller right click <<< add <<< preprocessor <<< JSR223 preprocessor

log.info("JSR223 预处理程序");

(8) Open the log, click Clear All, click Start, and view the log information

如图，每个 JSR223 Sampler 取样器都只迭代执行了3次，一共执行了6个取样器，执行每个 JSR223 Sampler 取样器时，都会在之前执行一次 JSR223 预处理程序
