fengye87 :
I'm quite a newbie to Spring boot, but here's the problem I'm facing now:
// Application.java
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Autowired
private Cluster cluster = null;
@PostConstruct
private void migrateCassandra() {
Database database = new Database(this.cluster, "foo");
MigrationTask migration = new MigrationTask(database, new MigrationRepository());
migration.migrate();
}
}
So basically, I'm trying to bootstrap a spring application, and after that, do some cassandra migrations.
I also have defined a repository for my user model:
// UserRepo.java
public interface UserRepo extends CassandraRepository<User> {
}
Now I'm trying to test my repo class using the following simple test case:
// UserRepoTest.java
@RunWith(SpringRunner.class)
@AutoConfigureTestDatabase(replace = Replace.NONE)
@DataJpaTest
public class UserRepoTest {
@Autowired
private UserRepo userRepo = null;
@Autowired
private TestEntityManager entityManager = null;
@Test
public void findOne_whenUserExists_thenReturnUser() {
String id = UUID.randomUUID().toString();
User user = new User();
user.setId(id);
this.entityManager.persist(user);
assertEquals(this.userRepo.findOne(user.getId()).getId(), id);
}
@Test
public void findOne_whenUserNotExists_thenReturnNull() {
assertNull(this.userRepo.findOne(UUID.randomUUID().toString()));
}
}
I would expect the test to pass, but instead, I got an error saying "No qualifying bean of type 'com.datastax.driver.core.Cluster' available". It looks like spring failed to autowire the cluster object, but why is that? How do I fix this? Thanks a lot!
JimHawkins :
The test environment needs to know where your beans are defined, so you have to tell it the location.
In your test class, add the @ContextConfiguration annotation:
@RunWith(SpringRunner.class)
@AutoConfigureTestDatabase(replace = Replace.NONE)
@DataJpaTest
@ContextConfiguration(classes = {YourBeans.class, MoreOfYourBeans.class})
public class UserRepoTest {
@Autowired
private UserRepo userRepo = null;
@Autowired
private TestEntityManager entityManager = null;
