Repository not executing methods in test - spring-boot

Question

I am trying to simply test a repository. Here is my test code:
#ContextConfiguration(classes = [
DatabaseTestConfiguration::class
])
#TestPropertySource(
properties = [
"spring.jpa.hibernate.ddl-auto=create-drop",
"spring.flyway.enabled=false"
]
)
#AutoConfigureTestDatabase
#AutoConfigureDataJpa
#AutoConfigureTestEntityManager
internal open class UserTest {
#Autowired
private lateinit var entityManager: TestEntityManager
#Autowired
private lateinit var userRepository: UserRepository
#Test
#Transactional
open fun whenSuccessfullyFoundAnyDuplicatedUserThenReturnTrue() {
val user = User()
user.name = NAME
user.surname = SURNAME
user.gender = GENDER
entityManager.persistAndFlush(user)
assertEquals(true, userRepository.anyDuplicate(
name = user.name,
surname = user.surname,
gender = user.gender,
))
}
companion object {
const val NAME = "John"
const val SURNAME = "Snow"
const val GENDER = "male"
}
Here is my DatabaseTestConfiguration:
#TestConfiguration
#EntityScan(value = [
"com.username.db.entities"
])
#EnableJpaRepositories(
"com.username.db.repositories"
)
class DatabaseTestConfiguration {
}
This is my repository:
#Repository
interface UserRepository: JpaRepository<User,Long> {
#Query(
"""
SELECT CASE
WHEN COUNT(user.id) > 0 THEN TRUE
ELSE FALSE END
FROM User user
WHERE user.name = :name AND user.surname = :surname AND user.gender = :gender
)
"""
)
fun anyDuplicate(
#Param("name") name: String?,
#Param("surname") surname: String?,
#Param("gender") gender: String?
): Boolean
}
This is my entity:
#Entity
#Table(name = "user")
class User {
#Id
#GeneratedValue(
strategy = GenerationType.SEQUENCE,
generator = "cdr_generator"
)
#SequenceGenerator(
name = "cdr_generator",
sequenceName = "cdr_seq",
allocationSize = 1
)
#Column(name = "id", nullable = false)
var id: Long? = null
#Column(name = "name", nullable = false)
var name: String? = null
#Column(name = "surname", nullable = false)
var surname: String? = null
#Column(name = "gender", nullable = false)
var gender: String? = null
}
Now when i am testing. this will always fail my test. When i debug it, i get that in my test it never enters userRepository.anyDuplicate() function. I assume that the problem is with configuring test. Can anybody help?
