Your testing journey in soapUI begins with a Project. And creating one is as easy as a right-click. If you want, you can directly add a WSDL, create sample requests for all the operations in the service, and even create a mock of the imported WSDL – all at once. You can even add a REST service – just tick a checkbox and soapUI takes care of the rest for you.
