I want to load test an application which does two things when I click on the button after filling the details -
- Make a call to 3rd party merchant API to validate the details entered
- Do some read & write operation in the DB.
So I want to get the performance of above and the only think I have access to is the application URL which I can open in the browser, fill the details and click submit.
The application is written in Java, so can anyone help me how to load test this kind of application?
