Snapshot Testing
Snapshot testing is a software testing technique that compares the current output of code against a previously approved “snapshot” to detect unintended changes. It is commonly used for UI components, API responses, serialized objects, and rendered output where exact or structured output consistency matters. When differences are detected, developers review and either accept the new snapshot or investigate the regression.
