With this tool you test your DMN decision table against the data from an Excel sheet.
The Excel sheet has to be structured like the decision table:
A Header line contains the input and output names from the decision tables. The output names must be preceded with Expected:
You can open the User Interface of the DMN Evaluator by double-clicking the dmn-evaluator.jar and upload the DMN table and the excel sheet to evaluate the decisions with the given values. Inspect the results:
For background testing you can run the java program com.camunda.consulting.dmn_excel_tester.DmnExcelTester with the filenames of the dmn table and the excel sheet from the console and check the outputs for the result.
Run mvn clean compile test assembly:single to create a single jar.
You can ignore the warning from the maven build, as the project only delivers a single jar file and nothing else.
Start the evaluation with java -jar target\dmn-evaluator.jar dmnFile excelFile.
This need at least Java 8 to build and run.
