soapUI is a free and open source desktop application for inspecting, invoking, developing, simulating/mocking and functional/load/compliance testing of web services over HTTP. It is mainly aimed at developers/testers providing and/or consuming web services (Java, .net, etc). Functional and Load-Testing can be done both interactively in soapUI or within an automated build/integration process using the soapUI command-line tools. Mock Web Services can easily be created for any WSDL and hosted from within soapUI or using the command-line MockService runner. IDE-plugins are available for eclipse, IntelliJ IDEA, NetBeans and a specialized eclipse-plugin for JBossWS. soapUI requires Java 1.5 and is licensed under the LGPL license.
