These components of IBM Rational Integration Tester can be installed with Rational Test Workbench:
With Rational Integration Tester, you get a scripting-free environment for developing tests for SOA messaging and business process integration projects. You can build tests by recording existing system behaviors or from requirements, by entering the data to send and the data that is expected in return. You can also create virtual services to remove test dependencies and enable earlier testing. Virtual services can be deployed by IBM Rational Test Virtualization Server to provide on-demand virtualized test environments that can support all phases of the test development lifecycle.
IBM Rational Test Control Panel is a server-based web application providing a central repository for virtualized services. The IBM Rational Test Control Panel allows you to use virtual services published with IBM Rational Integration Tester to create, share, and deploy virtualized test environments in IBM Rational Test Virtualization Server.
It also contains technology-specific components used by IBM Rational Integration Tester for recording SOA message conversations, HTTP(S) and JDBC traffic, and for monitoring middleware systems under test with minimal reconfiguration of client applications
