I managed to fix my tests by adding a application-test.properties on my project:

spring.datasource.url=jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=

spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.h2.console.enabled=true

And setting it up on my test:

@DataJpaTest
@AutoConfigureTestDatabase(connection = EmbeddedDatabaseConnection.H2)
@ActiveProfiles("test")
public class ExperienciaRepositoryTests {

Thank you for all your great help
