NoSuchBeanDefinitionException while running unit test when using @Configuration

Question

This issue is linked to my previous one at Spring @WebMvcTest with @EnableJpa* annotation.

So I moved @Enable* to @Configuration class but it breaks my other unit test classes, and that's why I had my previous question. I guess I didn't explain quite clearly before, so I try my best to do so in this question.

As seen in the answer, to resolve the error of "At least one JPA metamodel must be present!" when running test with @WebMvcTest, it is to move @Enable* annotation to a @Configuration class. While that did resolve the issue, many other issue occured in the other test class which I am not sure why it breaks those.

From what I see now, it breaks two type of test class. 1. Mail (@SpringBootTest) test class and 2. Repository (@DataJpaTest) test class.

Before I proceed, these are my snippet of the classes I think are relevant.

Main

@SpringBootApplication
public class SampleApplication {
 public static void main(String[] args) {
 SpringApplication.run(SampleApplication.class, args);
 }
}

AppConfiguration

@Configuration
@EnableCaching
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfiguration {
}

AccountServiceImpl

@Service
@RequiredArgsConstructor
public class AccountServiceImpl implements AccountService {
 private final AccountRepository accountRepository;
 private final RoleRepository roleRepository;
 private final PasswordEncoder passwordEncoder;
 private final ApplicationEventPublisher applicationEventPublisher;

MailServiceImpl

@Service
@RequiredArgsConstructor
public class MailServiceImpl implements MailService {
 private final JavaMailSender mailSender;
 private final MailTemplateContentBuilderImpl mailTemplateContentBuilder;

1. Mail (@SpringBootTest) test class

`

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MailServiceTest {
 @Autowired
 private MailService mailService;
 private GreenMail smtpServer;
 @Before
 // Removed below

`

And the error came as

2. Repository (@DataJpaTest) test class.

`

@RunWith(SpringRunner.class)
@DataJpaTest
public class AccountRespositoryTest {
 @Autowired
 private TestEntityManager entityManager;
 @Autowired
 private AccountRepository accountRespository;

`

And the error came as (see) https://pastebin.com/WBMccZUu. (as it's too long to include)

Remember that this two type of error wouldn't occur if I did not move to use @Configuration class. But if I don't move to @Configuration for @Enable* annotation, then the JPA metamodel error would occur.

(削除) My guess for the Repository issue, it couldn't see the @Configuration class? However, I tried to create the same @Configuration class using @TestConfiguration in my /src/test folder and called in ApplicationConfigurationTest.class.

@TestConfiguration
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfigurationTest {
}

And inside my Repository class, I did a @Import(ApplicationConfigurationTest.class) and it wouldn't work as well. It complains another issue though, of same nature.

(削除ここまで)

To be clear, this is what I did. I didn't meant that I did on the actual Repository class. It was on the test class.

@TestConfiguration
@Import(ApplicationConfiguration.class)
public class ApplicationConfigurationTest {
}

I also tried.

@TestConfiguration
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfigurationTest {
}
@DataJpaTest
@Import(ApplicationConfigurationTest.class) 
// Tried this as well, doesn't work
// @Import(ApplicationConfiguration.class)
public class AccountRespositoryTest {
 @Autowired
 private TestEntityManager entityManager;

But it still gives the same NoSuchBeanDefinitionException as before.

Kinda of clueless here. What should be the right way to do to ensure that my test can run properly.

Thank you. and let me know if I missed out any information.

• M. Deinum: @Import on a repository class is pretty much useless. Also you cannot reference test classes from your main classes. The @Import should be on your @TestConfiguration class (to reuse your existing configuration) or place it on your test class.
• M. Deinum: Also you would need to define basePackages to scan to the @EnableJpaRepository annotation (depending on where you put it).
• user1778855: I did the @Import correctly, I think. I have updated the post, please take a look. Correct me if I did it wrongly. Do you mean Component scan like > ComponentScan("com.sample")? I tried to add in the AccountRespositoryTest class as well, and it gave the same error (NoSuchBeanDefinitionException).

Answer 1

I think I have managed to resolve my issue, and I actually did came quite close to it previously with @M. Deinum comment.

It's quite simple actually.

As mentioned previously, I had a @TestConfiguration created. But I missed out to use basePackages, or rather I used it wrongly. So I was reading spring-data query method documentation, I came across this portion:

Also, note that the JavaConfig variant does not configure a package explicitly, because the package of the annotated class is used by default. To customize the package to scan, use one of the basePackage... attributes of the data-store-specific repository’s @Enable${store}Repositories-annotation.

And that's where it hits me. Hence, I added in the basePackages in @TestConfiguration to scan which I believe that because my test was in a different package, and when you are doing a @DataJpaTest, it wouldn't pick up the classes from other package (correct me if I'm wrong).

And then if you see Spring Auto-configured Tests Documentation, it also states (which I knew):

It often helps to load only the parts of the configuration that are required to test a "slice" of your application. For example, you might want to test that Spring MVC controllers are mapping URLs correctly, and you do not want to involve database calls in those tests, or you might want to test JPA entities, and you are not interested in the web layer when those tests run.

So with that, using @DataJpaTest, you need to specifically @import the @TestConfiguration.

@TestConfiguration
@EnableJpaAuditing
@EnableJpaRepositories(basePackages = "com.sample", repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfigurationTest {
}
@DataJpaTest
@Import(ApplicationConfigurationTest.class) 
public class AccountRespositoryTest {
 @Autowired
 private TestEntityManager entityManager;

And as I suspected, this also resolved the MailServiceTest Class issue I was facing as well.

It's a good lesson learnt, and pays well to read more carefully in the documentation.

Answer 2

Use classed = {SampleApplication.class} in SpringBootTest so SampleApplication will help to create all dependencies.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {SampleApplication.class}, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MailServiceTest {
 @Autowired
 private MailService mailService;
 private GreenMail smtpServer;
 }

• user1778855: Thanks for the help, but it doesn't work. I have also tried using ContextConfiguration("SampleApplication.class") as well.
• Bhushan Uniyal: can you add poc of it in github and share the link ?
• user1778855: I have added, please pull from github.com/bwgjoseph/beanexception-poc. I have added description in the README.md, thank you.
