I am writing a junit test for spring data repository. But i can’t autowire repository interface. Program is running if i run main method and spring can detect all repositories,services,entities but if i run a test it gives this error :
UnsatisfiedDependencyException: Error creating bean with name ‘repository.BookRepositoryTest’: Unsatisfied dependency expressed through field ‘bookRepository’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘app.repository.BookRepository’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
@RunWith(SpringRunner.class) @SpringBootTest(classes={BookRepository.class}) public class BookRepositoryTest { @Autowired private BookRepository bookRepository; @Test public void save() { Book book=new Book(); bookRepository.save(book); } }
public interface BookRepository extends JpaRepository<Book,Integer> { Book findByName(String name); }

Answer
The thing is, that your main and test packages differ:
BookRepository
is in app.entity.repository
and your test is in repository
. Try by aligning it and move your test to src/test/java/app/entity/repository
.
