Я хочу добавить тестовое покрытие в мои тесты JUnit для моих файлов BPMN. Я прочитал покрытие теста процесса Camunda BPM и попробовал пример Spring с конфигурацией теста Camunda Spring Boot Starter, но я получил исключение.
Код:
@RunWith(SpringRunner.class)
@Deployment(resources = {"test.bpmn"})
@ContextConfiguration(classes = {StandaloneInMemoryTestConfiguration.class})
public class MyTest {
@Autowired
private ProcessEngine processEngine;
@Rule
@ClassRule
public static ProcessEngineRule rule;
@PostConstruct
private void initRule() {
rule = TestCoverageProcessEngineRuleBuilder.create(processEngine).build();
}
@Test
public void test() {
}
}

Я также пытался собрать механизм процесса вручную с помощью метода initRule (удаление свойства автосвязи processEngine и аннотации класса @ContextConfiguration):
@PostConstruct
private void initRule() {
ProcessEngine processEngine = new StandaloneInMemoryTestConfiguration().buildProcessEngine();
rule = TestCoverageProcessEngineRuleBuilder.create(processEngine).build();
}
но я все еще получаю исключение:
