IBM Rational Test Virtualization Server is used to implement the behaviour defined in IBM Rational Integration Tester as permanent, high capacity stubs which can be deployed to any available environment. The stubs are not, except by licensing, limited in capacity or...
IBM Rational Integration Tester, formerly called IBM Green Hat, is designed to prevent integration problems by enabling iterative and agile development. It shows the system to be tested in diagrammatic form and has a repository of requirements to be handled by IBM Service Virtualization.
IBM Service Virtualization reproduces the network traffic between components. It then simulates an absent component and continues to test network traffic. This makes it possible to see if components can be removed and, in turn, build a larger number of cheap test environments.
