Spring JPA unit test with multiple database

Question

Friends, help me figure out the Spring JPA unit tests. When running the test, I get the error "datasource or data Source ClassName or jdbc Url is required". My Settings:

application-test.yml

spring:
  main:
    allow-bean-definition-overriding: true
  flyway:
    enabled: false

db:
  barsum:
    datasource:
      jdbc-url: 'jdbc:h2:tcp://localhost:9092/~/path/to/Bars600;DATABASE_TO_UPPER=false'
      driver-class-name: 'org.h2.Driver'
      username: 'sa'
      password: 'sa'
      pool-name: 'CP: BARSUM'
      maximum-pool-size: 1
      hibernate:
        show-sql: true
        dialect: 'org.hibernate.dialect.H2Dialect'
        hbm2ddl:
          auto: 'validate'

BarsumDBConfig class

@Configuration
@PropertySource( { "classpath:application.yml" } )
@EnableJpaRepositories(
        basePackages = "net.sunnikolay.rest.repo.barsum",
        entityManagerFactoryRef = "barsumEntityManager",
        transactionManagerRef = "barsumTransactionManager"
)
public class BarsumDBConfig {
    
    @Value( "${db.barsum.datasource.hibernate.dialect}" )
    private String dialect;
    
    @Value( "${db.barsum.datasource.hibernate.hbm2ddl.auto}" )
    private String hbmDdl;
    
    @Bean( name = "barsumDatasource" )
    @ConfigurationProperties( prefix = "db.barsum.datasource" )
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }
    
    @Bean( name = "barsumEntityManager" )
    public LocalContainerEntityManagerFactoryBean barsumEntityManager() {
        final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource( dataSource() );
        em.setPackagesToScan( "net.sunnikolay.rest.domain.barsum" );
        
        final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter( vendorAdapter );
        final HashMap properties = new HashMap();
        properties.put( "hibernate.hbm2ddl.auto", hbmDdl );
        properties.put( "hibernate.dialect", dialect );
        em.setJpaPropertyMap( properties );
        
        return em;
    }
    
    @Bean( name = "barsumTransactionManager" )
    public PlatformTransactionManager barsumTransactionManager() {
        final JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory( barsumEntityManager().getObject() );
        return transactionManager;
    }
    
}

and Test class

@ExtendWith( SpringExtension.class )
@TestPropertySource( locations = "classpath:application.yml" )
@SpringBootTest( classes = {
        BarsumDBConfig.class
} )
@ActiveProfiles( "test" )
@EnableJpaRepositories
class BarsumRepoTest {
    
    @Qualifier( "barsumEntityManager" )
    @Autowired
    private LocalContainerEntityManagerFactoryBean entityManagerFactoryBean;
    
    @Autowired
    private BarsumRepo repo;
    
    private static LocalDateTime startDt;
    private static LocalDateTime stopDt;
    private static String        calling = "3080";
    private static String        called  = "79035057473";
    
    @BeforeAll
    static void init() {
        DateTimeFormatter df = DateTimeFormatter.ofPattern( "yyyy-MM-dd HH:mm:ss" );
        startDt = LocalDateTime.parse( "2021-09-01 00:00:00", df );
        stopDt = LocalDateTime.parse( "2021-09-01 23:59:59", df );
    }
    
    @Test
    @Transactional( "barsumTransactionManager" )
    void findByCallDateTimeBetweenAndCallingNumberAndCalledNumber() {
        List list = repo.findByCallDateTimeBetweenAndCallingNumberAndCalledNumber(
                startDt, stopDt, calling, called
        );

        assertEquals( list.size(), 24 );
    }
    
}

When running my application in the development environment, I use spring-config-server. In the BarsumRepoTest class, I specified the "test" profile and created the application-test.yml file locally, I'm not sure that this is a good practice.
In any case, any answer will be useful for me.
