SoapUI is an open-source web service testing application for SOAP and REST web services.
Its functionality covers web service inspection, invoking, development, simulation and mocking, functional testing, load and compliance testing.
A commercial version, SoapUI Pro, which mainly focuses on features designed to enhance productivity, is also available.
SOAP UI is a very handy tool especially for testing SOAP Based web services.
We tested our Java SE web service with a client we wrote and we have tested the web service deployed into Glassfish using the Glassfish tester. However, we need a way to test SOAP web services in general and we should be able to test any web service available (and not just hosted on Glassfish). SOAP UI is such a tool that can help us testing web services easily.
There are other tools also, but SOAP UI is one of the most popular ones.
You can download and install SOAP UI like any other software or you can install it as an eclipse plugin and then use it from within the eclipse.
