SoapUI is an open-source tool for testing REST, SOAP, and GraphQL web services. It supports drag-and-drop creation of functional and regression tests, assertions, and data-driven tests. Teams can create service mocks from WSDL and mock SOAP or REST APIs. Listed protocols include SOAP/WSDL, REST, GraphQL, and JMS, and the tool runs on Windows, Mac, and Linux/Unix. Functional tests can be extended into load tests, including runs from command-line tools. SoapUI can configure incoming and outgoing WS-Security, covering encryption, signatures, SAML, keystores, and truststores. Named automation integrations for the open-source feature set include Maven, Hudson, Bamboo, JUnit, and Ant, and the tool can run from other CI tools. SoapUI Open Source is described for basic functional and performance testing; security testing appears among expanded capabilities associated with ReadyAPI. SmartBear describes SoapUI as a starting point for developers and testers and links to support and a community forum.
