lapots :
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;
}
Yuriy Tsarkov :
When the SpringBoot starts it scans classpath from the top to the 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 upper to the monolith package and everything gonna be fine
