JMeter中的周期性后台任务 [英] Periodic background task in JMeter

问题描述

我的测试计划中的请求使用我知道会在 1 小时后过期的授权令牌.我需要以某种方式每 59 分钟重新请求一次令牌，直到测试完成.有人可以建议最好的方法吗 - 看起来像 While Controller 测试永远不会完成停留在永恒的 while 循环中.

Requests in my test plan use an authorization token that I know expires in 1 hour. I need somehow to re-request the token every 59 mins until the test finishes. Could someone please suggest the best method for that - looks like with While Controller the test would never finish staying in eternal while loop.

推荐答案

1. 将另一个线程组添加到您的测试计划中.
2. 将其配置为永远运行(或有足够的循环来持续足够长的时间)
3. 将 Constant Timer 添加到第二个线程组.要使其每 59 分钟触发一次，请将 3540000 放入线程延迟"输入
4. 将您的令牌获取"逻辑置于计时器下方.
5. 如果您的令牌被存储为属性 - 主线程组将能够使用它.如果它是一个变量，你需要将它转换为一个属性，以便它 可以跨线程组使用，因为 JMeter 变量范围仅限于当前线程组.

1. Add another Thread Group to your test plan.
2. Configure it to run forever (or have enough loops to last long enough)
3. Add a Constant Timer to that second thread group. To make it fire each 59 minutes put 3540000 into "Thread Delay" input
4. Place your "token-obtaining" logic under the timer.
5. If your token is being stored as a property - main thread group will be able to use it. If it is a variable you'll need to convert it to a property so it could be used across thread groups as JMeter variables scope is limited to the current thread group only.
