Error running UT - BeanCreationException No property update found Custom Repository - spring-boot

Question

While running below UT CarRepositoryTest seeing following error Is I am missing any configuration here?
Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'itemRepository': Invocation of init
method failed; nested exception is java.lang.IllegalArgumentException:
Failed to create query for method public abstract void
com.dms.repository.interfaces.CustomItemRepository.update(java.util.List)!
No property update found for type InventoryItemEntity!

public class CarRepositoryTest {

#Autowired private TestEntityManager testEntityManager;

public void getCar_returnsCarDetails() throws Exception {
final String s = GenerateUUID.generateUUID();
Car savedCar = testEntityManager.persistFlushFind(new Car(s, "hybrid"));
Car car = this.repository.findByName(s);

assertThat(car.getType(), is("hybrid"));

}

I extends Serializable> extends JpaRepositoryFactoryBean<R, T, I> {
}
package com.dms.repository;
public class BaseRepositoryImpl<T, ID> extends SimpleJpaRepository<T, ID> implements BaseRepository<T, ID> {
private final EntityManager em;
#Transactional
#Override
public Specification<T> searchUsingRSQLParser(String query) {
return new RSQLParser().parse(query)
.accept(new CustomRsqlVisitor<>());
}
}
What configuration should be added/modify so that UT should not fail with a custom repository?
