[![Build Status](https://github.com/bpmn-io/dmn-testing-plugin/workflows/CI/badge.svg)](https://github.com/bpmn-io/dmn-testing-plugin/actions?query=workflow%3ACI)
[![Compatible with Camunda Modeler version 4.2+](https://img.shields.io/badge/Camunda%20Modeler-4.2+-blue.svg)](https://github.com/camunda/camunda-modeler)

This plugin allows to test DRD diagrams. Currently the plugin supports the following core features:
 * Parsing input variables for a given DRD and decision and letting the user define the respective values.
 * Starting an embeded lightweight Camunda DMN decision engine as `JAVA` sub-process.
 * Evaluating the DRD with the given input values and displaying the results.
