Hello.
I have a simple process:
SimpleTestProcess.bpmn (3.0 KB)
Running a test like:
package de.sternico.education.bpmn.process;
import static org.assertj.core.api.Assertions.in;
import static org.camunda.bpm.engine.test.assertions.bpmn.BpmnAwareTests.assertThat;
import static org.junit.jupiter.api.Assertions.assertEquals;
import org.camunda.bpm.engine.TaskService;
import org.camunda.bpm.engine.runtime.ProcessInstance;
import org.camunda.bpm.engine.task.Task;
import org.camunda.bpm.engine.test.Deployment;
import org.camunda.bpm.engine.test.ProcessEngineRule;
import org.camunda.bpm.engine.test.mock.Mocks;
import org.camunda.bpm.extension.process_test_coverage.junit.rules.TestCoverageProcessEngineRuleBuilder;
import org.junit.After;
import org.junit.Before;
import org.junit.ClassRule;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.context.junit4.SpringRunner;
import de.sternico.education.bpmn.definition.BpmnDefinitions;
import de.sternico.education.bpmn.delegate.simple.CreateTestDtosDelegate;
import de.sternico.education.bpmn.repository.simple.TestEntityRepository;
import de.sternico.education.bpmn.service.simple.SimpleTestService;
import de.sternico.education.bpmn.util.ProcessTest;
@RunWith(SpringRunner.class)
@DataJpaTest
@Deployment(resources = "simple/SimpleTestProcess.bpmn")
public class SimpleProcessTest extends ProcessTest
{
@Rule
@ClassRule
public static ProcessEngineRule processEngine = TestCoverageProcessEngineRuleBuilder.create().build();
@Autowired
private SimpleTestService simpleTestService;
@Autowired
private TestEntityRepository testEntityRepository;
@Before
public void setup()
{
Mocks.register(CreateTestDtosDelegate.class.getSimpleName(), new CreateTestDtosDelegate(simpleTestService));
}
@Test
public void testSimpleProcess()
{
ProcessInstance instance = processEngine.getRuntimeService()
.startProcessInstanceByKey(BpmnDefinitions.ProcessKeys.Simple.SIMPLE_TEST_PROCESS);
assertThat(instance).isWaitingAt("TASK_TEST_1");
TaskService taskService = processEngine.getTaskService();
Task taskTest1 = taskService
.createTaskQuery()
.processInstanceId(instance.getId())
.taskDefinitionKey("TASK_TEST_1")
.singleResult();
taskService.complete(taskTest1.getId());
assertThat(instance).hasPassed("TASK_CTD");
assertEquals(3, testEntityRepository.findAll().size());
}
@After
public void teardown()
{
Mocks.reset();
}
}
works, but invoking the same code (starting process instance, finish the human task which leads to invoking the service task) from a web layer test in spring in @RestController gives me:
Cannot resolve identifier 'CreateTestDtosDelegate'.
The delegate is:
package de.sternico.education.bpmn.delegate.simple;
import org.camunda.bpm.engine.delegate.DelegateExecution;
import org.camunda.bpm.engine.delegate.JavaDelegate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import de.sternico.education.bpmn.service.simple.SimpleTestService;
@Component("CreateTestDtosDelegate")
public class CreateTestDtosDelegate implements JavaDelegate
{
@Autowired
private SimpleTestService simpleTestService;
public CreateTestDtosDelegate(SimpleTestService aSimpleTestService)
{
super();
this.simpleTestService = aSimpleTestService;
}
public CreateTestDtosDelegate()
{
this(null);
}
@Override
public void execute(DelegateExecution execution) throws Exception
{
simpleTestService.createTestEntities("ganz", "schoen", "lustig");
}
}
Please note that in the green (not web layer) test, i use constructor injection for the ‘SimpleTestService’ (you told me so in another forum post, and it works fine), which i do not do in the web layer test because i assume that there the spring container does the autowiring for me.
Any suggestions?
P.S.: Running the process from camunda spring boot cockpit show the same behaviour (delegate expression can not be resolved).
P.P.S.: Like suggested in
Invoking a Spring Bean from a BPMN 2.0 Service Task | docs.camunda.org,
i added a configuration bean like
package de.sternico.education.bpmn.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import de.sternico.education.bpmn.delegate.simple.CreateTestDtosDelegate;
@Configuration
public class SimpleTestContext
{
@Bean
public CreateTestDtosDelegate createTestDtosDelegate()
{
return new CreateTestDtosDelegate();
}
}
but the beehaviour is still the same.
P.P.P.S.: Is it ok to use
@SpringBootApplication
@ComponentScan(basePackageClasses = {TrainDepartureService.class, FlatRentalService.class, SimpleTestService.class, CreateTestDtosDelegate.class})
public class BpmnTestApplication
{
or is it mandatory to use @ProcessAllpication to start up camunda spring boot?
P.P.P.P.S.: I think i exactly followed the instructions in
1.) Process model → Service Task → Delegate expression → ${createTestDtosDelegate}
2.) Delegate
@Component(value = "createTestDtosDelegate")
public class CreateTestDtosDelegate implements JavaDelegate
{
No clue why the delegate can not be found…
P.P.P.P.S.P.: I have made a new project setup where i refer to https://camunda.com/blog/2021/01/test-your-processes-with-junit-5/, and there, also, the delegate cannot be found. As in the old project, the web layer test also runs under junit5, i think in the way i mock my delegate in the case must be wrong:
@Before
public void setup()
{
Mocks.register(CreateTestDtosDelegate.class.getSimpleName(), new CreateTestDtosDelegate());
}
process:
<bpmn:serviceTask id="TASK_CTD" name="Create test dtos" camunda:delegateExpression="#{CreateTestDtosDelegate}">
Any suggestion for that?
Thank you.
