Service Virtualization
Service virtualization is a software testing technique that simulates the behavior of dependent systems, such as APIs, databases, mainframes, or third-party services, so applications can be developed and tested without requiring access to the real components. Virtual services reproduce expected responses, data conditions, latency, and error scenarios, enabling consistent and repeatable testing in complex distributed environments.
