Mocking (EN)

Mocking in Software Testing

Mocking is a technique in software testing where dependencies of a component are replaced by special objects called doubles. These mocks provide predefined responses to method calls without requiring actual external resources like databases or APIs to be called. Through mocking, tests can be executed in isolation, quickly and reliably, as they don't depend on external systems.
