Paralell HTTP Request dynamically

Question

I need perform some requests in paralell, I saw jp@gc - Parallel HTTP Requests, but I can´t found a way to load dynamically the URL´s in to the controller; my problem is the URLs to hit come from a JSON response; What is the way to indicate the URLs in a variable? Exist any way to manipulate the sampler using a JSR232 or beanshell to include the URLs? Or maybe how can I do a Thread Group and a HTTP sampler in execution time?

Kind Regards,

Alejandro Longas H.

If you're looking for a code to add URLs to the Parallel HTTP Requests sampler in the JMeter runtime:

Add setUp Thread Group to your Test Plan
Add JSR223 Sampler to the setUp Thread Group

Put the following code into "Script" area:

SampleResult.setIgnore()
def testTree = ctx.getEngine().test
def parallelSamplerSearch = new org.apache.jorphan.collections.SearchByClass<>(com.blazemeter.jmeter.http.ParallelHTTPSampler.class)
testTree.traverse(parallelSamplerSearch)
def parallelSampler = parallelSamplerSearch.getSearchResults().first()
parallelSampler.addURL('http://example.com')
parallelSampler.addURL('http://jmeter.apache.org')

That's it, now Parallel HTTP Request sampler should fire 2 requests to the above URLs simultaneously.

Hi @Dmitri T, I´m working with your recomendations, but I see only 6 six request performed in parallell, the others is executed with a 3 sec of delay, maybe could be something of configuration? Maybe could be a limitation in de jp@gc - Parallel HTTP Requests? I was reading the documentation and I don´t found nothing relate that; maybe you know? I need perform 96 request in parallel
