[P48] JMeter assertion duration (Duration Assertion)

---

1. Description of the Duration Assertion parameter

可以控制取样器的执行是否超过某个时间，如果超时则报错，持续时间断言器也叫超时断言器

使用场景：我们一般用超时断言器来检测业务是否达到某个超时时间

使用频率：一般

Right click >>> Add >>> Assertion >>> Assertion duration (Duration Assertion)

Apply to

• Main sample and sub-samples: Act on the parent node sampler and the corresponding child node sampler; assert all samplers

• Main sample only: only acts on the parent node sampler; asserts only on the main sampler

• Sub-samples only: only applies to sub-node samplers; asserts only on sub-samplers (sub-samplers: original samplers, processed by post-processors, and obtain request results)

Duration to Assert (assertion duration)

• Duration in milliseconds (duration (milliseconds)): assertion execution time

2. Test plan design

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

• Number of cycles: 10

• Other parameters can be default

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

log.info("我是：JSR223 Sampler");

(3), right click on the thread group <<< add <<< assertion <<< assertion duration

• Duration (ms): 100

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

(5) Click to start, click to view the result tree, and view the request information

如图，取样器都请求成功，断言成功

(6), modify JSR223 Sampler

• language: java

log.info("我是：JSR223 Sampler");
Thread.sleep(1000L);

(7) Click to clear all, click to start, click to view the result tree, and view the request information

如图，取样器都请求失败，断言失败；断言持续时间 中给出了失败原因
