问题 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. 回答1: Put the variable as ${url} in

Limit values of custom JMeter Properties at runtime

阅读更多关于 Limit values of custom JMeter Properties at runtime

问题 We've a distributed JMeter setup as described here - How to Change JMeter´s Load During Runtime The test plan (JMX file) is provided by the user. Hence, we don't know the property names used in there. During runtime, the user can provide property names and values that we will directly pass to JMeter setup through beanshell script. In this setup, can we put a limit/cap on values of certain JMeter properties (which can potentially affect our provided resources) that can be changed by the user

Use JMeter Proxy against specific Proxy to record requests

阅读更多关于 Use JMeter Proxy against specific Proxy to record requests

问题 I have an Electron App which should be started through Proxy Proxy_A. I Would like to make a Loadtest to the Backend. To my basic understanding when I want to record the request using JMeter, I should configure a script recorder which creates a proxy Proxy_B on its own. I should then use JMeter proxy as a proxy to my app so that the traffic could be recorded. Now I am little bit lost. How could I tell JMeter to accepts and forwards the request from my Proxy_A to JMeter Proxy Proxy_B? Edit
