How to handle Jmeter tests

Question

Measuring the load time of an ( web-based application)

When a user clicks on a link, the web-based Application sends a Request to the server

I have tried to take the above post request and loop it under While loop controller with a condition. But the while loops just loops forever.

Answer 1

There are following possible origins for these requestId dynamic variable:

1. It may be present in response URL as the result of a redirection
2. It may be present in response headers
3. It may be present in response body
4. It is generated on the client side (browser) using JavaScript

In first 3 cases you need to correlate the value using a suitable post-processor, in 4th case you need to replicate the JavaScript code which is generating the value using JSR223 PreProcessor and Groovy language

We cannot comment anything on your While Controller issue apart from very obvious statement that the While Controller will execute its child(ren) until the variable or function which you put in the "Condition" are resolves to true, the evaluation result including any nested variables can be observed using i.e. Debug Sampler
