Null pointer when creating a unit test for JPAQueryFactory

Question

I have this method to update a table in DB, it works correctly, until I create the unit test for it:

 public class ReferentialAdapter {
        private final JPAQueryFactory queryFactory;
        
        public void enableServiceConfigs(String roleCode, String countryIsoCode, List<String> services) {
            QServiceConfigEntity qServiceConfigEntity = QServiceConfigEntity.serviceConfigEntity;
            QCountryRoleEntity qCountryRoleEntity = QCountryRoleEntity.countryRoleEntity;
            QServiceEntity qServiceEntity = QServiceEntity.serviceEntity;
            JPQLQuery<Long> countryRoleId = JPAExpressions.select(qCountryRoleEntity.id).from(qCountryRoleEntity)
                    .where(qCountryRoleEntity.country.isoCode.equalsIgnoreCase(countryIsoCode).and(qCountryRoleEntity.role.code.equalsIgnoreCase(roleCode)));
    
            BooleanExpression whereCondition = qServiceConfigEntity.countryRole.id.eq(countryRoleId)
                    .and(qServiceConfigEntity.service.id.in(serviceIds));

            queryFactory.update(qServiceConfigEntity)
                    .where(whereCondition)
                    .set(qServiceConfigEntity.isEnabled, Boolean.TRUE)
                    .execute();
        }
    }

configuration for JPAQueryFactory:

@Configuration
public class QueryDslConfig {

    @PersistenceContext
    private EntityManager entityManager;

    @Bean
    public JPAQueryFactory jpaQueryFactory() {
        return new JPAQueryFactory(entityManager);
    }
}

but this test throw a null pointer exception when call the execute() for the update.

@ExtendWith(MockitoExtension.class)
class ReferentialAdapterTest {

    @Mock
    private  JPAQueryFactory queryFactory;

    @InjectMocks
    private ReferentialAdapter referentialAdapter;
  
    @Test
    void shouldEnableServicesConfig() {
        String roleCode = "CA_ICS_HBE";
        String countryIsoCode= "FR";
        List<String> services = Arrays.asList("VT" , "CAF");
        referentialAdapter.enableServiceConfigs(roleCode,countryIsoCode,services);
        verify(queryFactory,times(1)).update(any());
    }
}
