Question

Hi how can I implement the following scenerio in Jmeter. 1. Thread group starts 5 threads. 2. 5 threads starts there execution. 3. all the thread pause until sampler is exteded(need to be executed only ones by any thread). 4. after execution of the sampler, all the threads resume their execution.

Updated the question and image.

Is there any way to pause all the threads until, samplerA is executed by any thread ( irrespective of the thread count this need to be executed only once) after execution of this sampler all the threads can continue execution. Click for the image

Answer 1

Organize your test as follows:

• Sampler 1

• If Controller condition: ${__groovy(ctx.getThreadNum() == 0,)}

  • Request 1
    • JSR223 PostProcessor code: props.put('continue', 'false')
• While Controller condition: ${__P(continue,)}
  • Test Action Sampler: Target: All Threads, Duration: 100
• Request 2
