IBM Rational Test Virtualization Server [EOL] vs Parasoft Virtualize comparison

Testing environments are often expensive and can have limited availability. IBM Rational Test Virtualization Server helps you shift testing to the left by removing dependencies on components that are unavailable or already in use. These components are simulated at the API layer, supporting a wide variety of technologies, allowing your team to test the riskiest elements earlier in the delivery lifecycle.

Go beyond basic mocking and stubbing to create a more robust simulation for APIs and services. Deploy a “digital twin” of your test environment to use as a sandbox for partner development or as a virtual endpoint for internal testing. Parasoft's service virtualization tool, Parasoft Virtualize, enables testers and developers to simulate services or data when access is unavailable or unreliable. The virtual assets can be easily integrated with other testing teams and visualized in a configurable test environment for faster failure detection and debugging with an intuitive codeless interface.
