Невозможно запустить Spring test test runner с JPA без HSQL

Question

Мы пытаемся написать тестовый пример для приложения, которое работает как с MyBatis, так и с JPA в Spring, используя AbstractRoutingDataSource, Mockito; мы можем высмеивать mybatis-код. Когда мы интегрируем JPA, @SpringBootTest пытается получить доступ к источнику данных AbstractRoutingDataSource, для которого он не работает.

@RunWith(SpringRunner.class) 
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, classes = MyWebService.class) 
@ComponentScan(basePackages = { "com.me.xyz" }) 
@EnableAutoConfiguration 
public class MyWebServiceTest extends Mockito { 


} 

Мы хотели бы использовать Mockito в полной мере расширить таким образом, мы не хотим использовать базу данных HSQL/H2 для нашего тестирования, которое увеличивает наш код для вставки все требуемые данные. Пожалуйста, найдите в журнале ниже ошибки,

Мы пытались дразнить AbstractRoutingDataSource, но он по-прежнему бросает другую ошибку.

Answer 1

Это может быть полезным, посмотрите на secion под названием "Тестирование ломтиков приложений"

https://spring.io/blog/2016/04/15/testing-improvements-in-spring-boot-1-4

Вы можете добавить свой код? Идея срезания теста Spring boot - вы издеваетесь над целыми уровнями, так что, например, если вы хотите, чтобы уровень MVC не интересовался уровнем MyBatis/HIbernate вообще, как это (см. Ниже).

Если вы не используете аннотации для нарезки, Spring Boot попытается создать экземпляр диспетчера сущностей и т. Д., Который, похоже, вам не нужен.

@RunWith(SpringRunner.class) 
@WebMvcTest(UserVehicleController.class) 
public class UserVehicleControllerTests { 

@Autowired 
private MockMvc mvc; 

@MockBean 
private UserVehicleService userVehicleService; 

Answer 2

У меня была аналогичная проблема. Найден ответ в следующей статье:

http://www.devthoughts.pl/2016/08/02/datajpatest-from-spring-boot/

Spring загрузки пытается заменить источник данных с HSQL по умолчанию.

Использование аннотаций @AutoConfigureTestDatabase в сочетании с теми, необходимыми для загрузки и тестирования Spring JPA, решить мою проблему:

@RunWith(SpringRunner.class) 
@DataJpaTest 
@AutoConfigureTestDatabase(replace = Replace.NONE) 

Надеется, что это помогает.
