SOAP UI provides easy integration with different web services like SOAP and REST along with feature of Load Testing. Below I will show how to setup SOAP UI for doing load testing. To start with you need to have SOAP UI installed in the system. In the example I will consume REST webservice. Web Service end point is http://localhost:9081/UserService/users Lets start with the load testing setup now. Start SOAP UI tool and setup the REST webservice call and do a round of testing to ensure that tool is able to connect to the service and is able to get the response. Following screens shows the same. Setup REST Project Create New Project Right click on the Project and click on create REST Project. After providing the URL in above alert box, You will get below windows where you can see the various options like Method Endpoint Resource Input parameter Once you provide all the necessary configuration required for your webservice do test and once you see the expected response in the output window...
