When you write several JUnit classes, it becomes uncomfortable to run them individually. You can run all the Xtend tests in a package by right-clicking on the corresponding package in the xtend-gen folder and select Run As | JUnit Test.
If you need more control over the tests that must be run or you want to group some tests, you can write a JUnit Test Suite. For example, you can write a suite for tests which are not related to generation as shown in the following Java class:
import org.junit.runner.RunWith; import org.junit.runners.Suite; @RunWith(Suite.class) @Suite.SuiteClasses({ EntitiesParsingTest.class, EntitiesFormatterTest.class, EntitiesValidatorTest.class }) public class EntitiesNotGeneratorRelatedTests { }
You can run such suite as a standard JUnit test, and it will run all the test methods in all the test classes specified in the test suite.
