Definition of Service Virtualization
Application Service virtualization tracks the behavior of software components and removes the reliance of such components on development and testing teams working on the app development. Such controls are needed when a component connected to the application under test is, not yet completed or still under development .If the development is controlled by a third-party or partner or it is accessible for testing only in limited capacity or at inconvenient times then service virtualization is the functional choice.
Brief Description of Service Virtualization
Components which are Difficult to configure in a test environment and required simultaneous access by different teams with varied test data setup and other requirements could be handled through service virtualization. It is helpful in expensive testing scenarios where the assessment is Restricted for price or over load.
term “service virtualization” though emphasizes on virtualizing services, but in real the service virtualization broaden across all facets of complex applications like , databases, mainframes, or ESBs, service virtualization, virtualizes specific regions of dependent behavior that involves in the development and testing tasks. Through such convenience the developers or testers get their testing target need without being awaited for the entire service to be completed. Service virtualization thus formulates a “virtual asset” that replicates the behavior of a real component which is required to put into effect the application under test,
