I have swt components in my code which I have mentioned here.This is swt gui from where user can select inputs from GUI and perform job.I want to unit test that job and measure performance.But I have no idea how to take input from GUI and give it to jmeter.Or can we bind jmeter code into existing API without writing jmetersmpler.
I have two question in my mind that i want to share with you:
1)Can Jmeter support swt GUI testing?If yes than can you provide simple demo
2)How to implement jmeter in swt GUI with existing code and how to test them.

Answer 1

JMeter cannot test standalone desktop applications out of the box. Normally load testing of the desktop applications is not required as they are used only by single person and if the application reaction time is ok - you don't need to take any extra steps.
However if your application communicates with the backend server - you might want to test the server to check how does it handle the load from multiple concurrent application instances. In that case here are the options:
If application uses HTTP or HTTPS to communicate with the backend server - you can capture the requests via JMeter's HTTP(S) Test Script Recorder and then replay them
If other protocol is being used - you can check available JMeter Samplers and JMeter Plugins to see whether protocol is being supported and use the relevant sampler
There are also options to do some coding via the following Test Elements:
if you have JUnit tests - you can reuse and run them in multithreaded manner via JUnit Request Sampler
there is also possibility to use one of scripting languages which comply with JSR-223 specification like javascript, jexl, beanshell, etc.
