Subject Proposal of AUTOMATIC FEATURE to extract dynamic data from previous response and sending in next request.
Date Tue, 19 Mar 2019 16:54:05 GMT

To enhance usability of tool NEC wants to propose a plug-in for Jmeter, that will extract
data from previous request and fill that data in next request.

In some web applications, Users are required to take some data from previous response which
will be input for new request. This Activity can be done with the help of "Regular Expression

How it works:
It save values based on user defined rules and saves in variable.
This variable is later used in sending that data in upcoming requests.

Pain Point/Challenges :

1.       Applying rule for saving data in variable is really effort taking.

2.       Often data is not available in response body every time, user needs to find whether
its available in body or header or API response or subsequent requests. User has to find it

3.       It works on hit and try.

Available workarounds:
There are some available work around in market to overcome the situation like Blazemeter and
But user has to upload their scripts to these websites.

But every organization will not be interested to share their API request/Response data with
third party.

Proposal :
NEC wants to deploy a plug-in that will work within Jmeter to overcome with this uneasiness.

Scripting size will reduce by 80%
Human error chances will reduced.
Will make product more user interactive.
Will increase ease of use interactivity.

Will apache be interested to take this approach?
