APIs (Application Programming Interfaces) enable software components to interact with each other. API Virtualization creates stand-in simulations of the real APIs.
API Virtualization removes obstacles during development and testing caused by unavailable API dependencies. It brings benefits like increased productivity and improved quality.
Mocks, Stubs, Fakes, and other Test Doubles can help. Specialized software makes it easy to take the next step to API Virtualization for a much more sophisticated simulation of APIs.
