Goal : Automate Drools Engine testing using Excel document for a business validation.
- JDK 11+
- Maven 3.8+
- JUnit 5.7+
- Drools 8.16+
- Zerocell 0.5.1
Rules are developed with Excel Drools feature. They can be found into src/main/resources/net/a/g/brms/dat/rule/excel folder. Please see Drools documentation how to develop with it.
Excel document can be found into src/test/resources folder
JUnit 5 can manage dynamic test case. It uses Factory pattern to load a set of test cases from Excel file. We could also use some other providers like a CSV file or Database. To parse Excel file we gonna use Zerocell library providing a very simple and flexible Excel reader.
DroolsBatchFactoryTest class is the principal class (the factory). It reads Excel file, loads it into a list of ItemUnitTestRow and create a list of test case excutor DroolsUnitTestExecutor. Class DroolsUnitTestExecutor provides the main function to validate a test, will use ItemUnitTestRow to create some input parameters, execute Drools engine and reuse ItemUnitTestRow for testing the result. This class should manage the whole test flow and, must be robust and reliable.
The command to execute test.
mvn test
The result of the previous command.
