consider 2 request in a thread group, How to execute the 1request for one time and remaining request as per the thread count

Question

1. Assume 2 requests in a thread group. Thread count is 100
2. Http sampler A, Http sampler b
3. I have extracted a set of values using JSON extractor and stored in a variable
4. I used the extracted values in request sampler b (added controller for each extracted values)
5. when I try to execute this script both the request ran for 100times
6. So I have added once the only controller for the 1st request. Even though both the request ran for 100times

I want to execute Request A for one time and request B for 100times. How can we achieve this?

Answer 1

As per documentation JMeter Variables are local to the thread (virtual user) so if you use variables from HTTP Sampler A in HTTP Sampler B you need to execute HTTP Sampler A once per user which gives you 100 executions.

If you're looking for a way to execute HTTP Sampler A only once, no matter how many threads you have:

1. Add setUp Thread Group to your Test Plan and keep threads/loops count as 1
2. Put your HTTP Sampler A under that setUp Thread Group
3. Save each value from JSON Extractor into a JMeter Property using __setProperty() function
4. In your main Thread Group use __P() function to access the values extracted in the setUp Thread Group
