Web service development tools

SoapUI is an open-source web service testing application for Simple Object Access Protocol (SOAP) and representational state transfers (REST). Its functionality covers web service inspection, invoking, development, simulation and mocking, functional testing, load and compliance testing. A commercial version, ReadyAPI (formerly SoapUI Pro), which mainly focuses on features designed to enhance productivity, was also developed by Eviware Software AB. In 2011, SmartBear Software acquired Eviware.
