Flowable JUnit error

Flowable Engine
1

Hi,

Trying to run a Flowable process in JUnit

First in the documentation (https://www.flowable.org/docs/userguide/index.html#apiUnitTesting) there is an error here private ProcessEngine procesEngine; where ‘s’ is missing in processEngine

  private ProcessEngine procesEngine;
  private RuntimeService runtimeService;
  private TaskService taskService;

  @BeforeEach
  void setUp(ProcessEngine processEngine) {
    this.processEngine = processEngine;
    this.runtimeService = processEngine.getRuntimeService();
    this.taskService = processEngine.getTaskService();
  }

Second with this JUnit code

@FlowableTest
public class FlowableProcessTest {

  private ProcessEngine processEngine;
  private RuntimeService runtimeService;
  private TaskService taskService;
  
  
  @BeforeEach
  public void setUp(ProcessEngine processEngine) throws Exception {
    this.processEngine = processEngine;
    this.runtimeService = this.processEngine.getRuntimeService();
    this.taskService = this.processEngine.getTaskService();
  }

  @Test
  @Deployment
  public void test() {
    runtimeService.startProcessInstanceByKey("test");

    Task task = taskService.createTaskQuery().singleResult();
    assertEquals("My Task", task.getName());

    taskService.complete(task.getId());
    assertEquals(0, runtimeService.createProcessInstanceQuery().count());  }

}

i’m getting this error

org.junit.jupiter.api.extension.ParameterResolutionException: Failed to resolve parameter [org.flowable.engine.ProcessEngine arg0] in executable [public void com.tgwt.app.process.FlowableQuoteTest.setUp(org.flowable.engine.ProcessEngine) throws java.lang.Exception]

Hi @radar1975

Are you sure that you’ve run FlowableProcessTest ?

Yes … i think it’s a JUnit Eclipse issue since at the end of the exception we have

Caused by: java.lang.NoSuchMethodError: org.junit.jupiter.api.extension.ParameterContext.isAnnotated(Ljava/lang/Class;)Z

I’m looking to update the JUnit 5 Librairy in Eclipse

I will keep you posted

Ok issue was fixed by adding to project pom.xml
