Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

I am using Spring Data JPA and Spring Boot. The layout of the application is this

main
    +-- java
        +-- com/lapots/game/monolith
            +-- repository/relational
                +--RelationalPlayerRepository.java
            +-- web
                +--GrandJourneyMonolithApplication.java
                +-- config
                    +-- RelationalDBConfiguration.java
test
    +-- java
        +-- com/lapots/game/monolith
            +-- repository/relational
                +-- RelationalPlayerRepositoryTests.java
            +-- web
                +-- GrandJourneyMonolithApplicationTests.java

The repository for my object looks like this

public interface RelationalPlayerRepository extends JpaRepository<Player, Long> {
}

Additionally for the repositories I provided a configuration

@Configuration
@EnableJpaRepositories(basePackages = "com.lapots.game.monolith.repository.relational")
@EntityScan("com.lapots.game.monolith.domain")
public class RelationalDBConfiguration {
}

My main application looks like this

@SpringBootApplication
@ComponentScan("com.lapots.game.monolith")
public class GrandJourneyMonolithApplication {

    @Autowired
    private RelationalPlayerRepository relationalPlayerRepository;

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

    @Bean
    public CommandLineRunner initPlayers() {
        return (args) -> {
            Player p = new Player();
            p.setLevel(10);
            p.setName("Master1909");
            p.setClazz("warrior");

            relationalPlayerRepository.save(p);
        };
    }
}

Test for application looks like this

@RunWith(SpringRunner.class)
@SpringBootTest
public class GrandJourneyMonolithApplicationTests {

    @Test
    public void contextLoads() {
    }

}

The test for repository looks like this

@RunWith(SpringRunner.class)
@DataJpaTest
public class RelationalPlayerRepositoryTests {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private RelationalPlayerRepository repository;

    @Test
    public void testBasic() {
        Player expected = createPlayer("Master12", "warrior", 10);
        this.entityManager.persist(expected);
        List<Player> players = repository.findAll();
        assertThat(repository.findAll()).isNotEmpty();
        assertEquals(expected, players.get(0));
    }

    private Player createPlayer(String name, String clazz, int level) {
        Player p = new Player();
        p.setId(1L);
        p.setName(name);
        p.setClazz(clazz);
        p.setLevel(level);
        return p;
    }
}

But when I try to run the tests I get the error

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.041 sec <<< FAILURE! - in com.lapots.game.monolith.repository.relational.RelationalPlayerRepositoryTests

What is the problem? Domain Player loooks like this

@Data
@Entity
@Table(schema = "app", name = "players")
public class Player {
    @Id
    @GeneratedValue
    private Long id;

    @Transient
    Set<Player> comrades;

    @Column(unique = true)
    private String name;

    private int level;

    @Column(name = "class")
    private String clazz;
}

In my case

@ContextConfiguration
class Productrestapi2ApplicationTests {

    @Test
    void contextLoads() {
    }

}

Adding @ContextConfiguration helped

I had this problem when running the tests in Maven not in Eclipse. To solve the issue, I had to move the annotations from parent class to actual test child class

@ActiveProfiles("integrationtests")
@SpringBootConfiguration
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)

The packages src/test/java and src/main/java should match. I had the same issue where

  • The src/main/java packages were starting with com.comp.example but
  • The src/test/java packages were starting with com.sample.example

Because of this spring boot application was not able to pickup the configuration of the application, which it picks up from @SpringBootApplication class. So test case should fall under the same packages where @SpringBootApplication in src/main/java is written.

When Spring Boot starts, it scans the classpath from top to bottom of the project to find the config file. Your config is under another files and that is a reason of the problem. Move you config higher up to the monolith package and everything will be fine.

Although not a direct answer to the OP Question, I was able to solve my own experience of the same error message (as the Title of this Question) in IntelliJ IDEA:

Some part of the "Maven Dance"™️ {mvn clean compile, [IntelliJ] Reload All Maven Projects} solved it for me.

For me it worked by adding the path to the main class as below

@SpringBootTest(classes = {com.ghimire.bookApi.SpringBookApiPracticeApplication.class})

if your project has no testable code in it and you have the default test block in the spring boot default test class

@SpringBootTest

class DemoApplicationTests {
    @Test
    void contextLoads() {
    }
}

delete the test annotation and the the contextLoads() method. to this

@SpringBootTest
class DemoApplicationTests {
}

I was able to resolve this problem only after including in the @SpringBootTest classes both the context configuration class and the application class.

In my case this was due to some [move|copy/paste] of classes. For some, the package clause was either [not updated correctly|not present] and the changes were not picked up but the IDE.

Anyways, review your project packaging.

The Test src/test/java files should also follow the same directory structure as in src/main/java.

Delete the file module-info.java. This worked for me.

@SpringBootTest has a parameter named classes. It accepts an array of classes for configuration. Add the class for the config file to it, for example:

@SpringBootTest(classes={com.lapots.game.monolith.web.GrandJourneyMonolithApplication.class})
