Error running Junit Tests in Spring Boot 2.0.0.M6 - spring

Question

I've generated a Spring Boot web application using Spring Initializer, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file.
Technologies used:
Spring Boot 2.0.0.M6 , Java 8, maven
I have this config file
#Configuration
#Profile("prod")
#EnableTransactionManagement /* Defines a Bean Post-Processor (proxies #Transactional bean) */
public class PersistenceConfig {
#Bean
public MetricsRepository metricsRepository() {
return new JdbcMetricsRepository();
}
]
In the app. I have this service that works fine
#Service
public class ExcelService {
#Autowired
MetricsRepository jdbcMetricsRepository;
..
}
I also have this Junit test:
#ContextConfiguration(classes={PersistenceConfig.class})
#RunWith(SpringRunner.class)
public class JdbcMetricsRepositoryTests {
#Autowired
MetricsRepository jdbcMetricsRepository;
#Test
public void testGetHotelReservations() throws DataAccessException, SQLException {
jdbcMetricsRepository.getHotelReservations();
}
}
but when running the tests I got this error:
Error creating bean with name 'com.iberia.repository.JdbcMetricsRepositoryTests': Unsatisfied dependency expressed through field 'jdbcMetricsRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.iberia.repository.MetricsRepository' available: expected at least 1 bean which qualifies as autowire candidate.

You should add #SpringBootTest annotation to your testclass.
#SpringBootTest
#ContextConfiguration(classes={PersistenceConfig.class})
#RunWith(SpringRunner.class)
public class JdbcMetricsRepositoryTests {
