# Handling test data in the data model

The data model is the central element of business analysis.

### Test data in the model

* enable rapid prototyping of forms and processes,
* allow verification of BPMN process logic and services,
* enable full end-to-end testing without integration with external systems.

### Test methods

* tests using defaultValue,
* tests using local data sources = providers.
