It builds dynamic dummy data according to YOUR data model/domain. How? It uses the names and types of each property of the user-provided JSON and infers appropriate and random data for each. Most dummy/mock data providers have predefined structures that don't match with the domain/data model that the developer needs or provide functions calls that are too manual. But Data Mocker fixes this. It makes it easy and offers the most flexibility possible.
