No qualifying bean of type repository when running test but not main application - spring-boot

Question

I'm developing a Spring Boot application following TDD methodology. I've created the main classes (controller, service and repository) this way:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
#Service
public class CrimeServiceImpl implements CrimeService{
#Autowired
private CrimeRepository repository;
...
Controller:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class CrimeController {
#Autowired
private CrimeServiceImpl service = new CrimeServiceImpl();
Repository:
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface CrimeRepository extends JpaRepository<Crime, Long>{
}
This is the project structure:
If I run the application normally, no error. The classes' methods are empty. Then I've created a test class like this:
#RunWith(SpringRunner.class)
#ContextConfiguration(classes = CrimeServiceImpl.class)
#ComponentScan("com.springmiddleware")
#AutoConfigureMockMvc
#SpringBootTest
public class TestCrimeService {
//Calling method getAllCrimes works
#Test
public void returnAllCrimesExists() throws NoSuchMethodException, SecurityException {
List<Crime> list = new ArrayList<>();
assertTrue(this.service.getAllCrimes() == list);
}
And if I run this, the following error is shown and the test fails:
NoSuchBeanDefinitionException: No qualifying bean of type 'com.springmiddleware.repository.CrimeRepository' available: expected at least 1 bean which qualifies as autowire candidate.
I've checked all annotations and it seems to me that all is ok, and I thought if I missed something, even in the normal run the application would fail. What did I got wrong?

Answer 1

I wanted also to make a test class for a JPARepository, and I also encountered the same error message:
NoSuchBeanDefinitionException: No qualifying bean of type
'SomethingRepository' available:
expected at least 1 bean which qualifies as autowire candidate.
I could make it work by adding the 2 following annotations on top of the test class:
#EnableJpaRepositories(basePackageClasses = SomethingRepository.class) // repository
#EntityScan(basePackageClasses = Something.class) // entity of the repository
Now it looks like:
#RunWith(SpringRunner.class)
#EnableJpaRepositories(basePackageClasses = SomethingRepository.class) // repository
#EntityScan(basePackageClasses = Something.class) // entity of the repository
#SpringBootTest(classes = MyDbUnitTestApp.class) // does some #ComponentScan and #EntityScan on the repositories/entities package, and #EnableAutoConfiguration
#ActiveProfiles(Profiles.myTestProfile)
#DatabaseSetup(value = {
"/datasets/dataset1.xml" }, type = DatabaseOperation.CLEAN_INSERT)
public class SomethingRepositoryTest {
#Autowired
private SomethingRepository sut;
#Test
public void findById() {
Something something= sut.findById(1L);
Assert.assertEquals("foobar", something.getName());
}
}
