Autoconfigure ReactiveCrudRepos in integration tests - spring-boot

Question

I'm having some difficulty in writing some Integration tests. I have something like so
#RunWith(SpringRunner.class)
#SpringBootTest(classes = Service.class)
public class ServiceTest {
#Rule
public PostgreSQLContainer postgres = new PostgreSQLContainer();
#Autowired
Service Service;
#Before
public void setUp() {
PostgresqlConnectionFactory connectionFactory = new PostgresqlConnectionFactory(PostgresqlConnectionConfiguration.builder()
.host(postgres.getHost())
.port(postgres.getFirstMappedPort()) // optional, defaults to 5432
.username(postgres.getUsername())
.password(postgres.getPassword())
.database(postgres.getDatabaseName()) // optional
.build());
Resource resource = new ClassPathResource("sql.sql");
Mono<PostgresqlConnection> mono = connectionFactory.create();
mono.map(connection -> connection
.createStatement(Helpers.asString(resource))
.execute()).block();
}
#Test
public void test() {
Request Request = new Request();
request.setName("name");
Mono<Item> itemMono = Service.createNewHub(hubRequest);
Item item = itemMono.block();
Assert.assertEquals(1L, 1L);
}
}
And my Service.class looks like the below
#Service
public class Service {
private Repository repository;
public Service(Repository repository) {
this.repository = repository;
}
public Flux<Item> getAllItems() {
return repository.findAll();
}
}
And my repo
#Repository
public interface Repository extends ReactiveCrudRepository<Item, Integer> {
}
My error is the following
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.Repository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
While all of the code I have written in the application is able to be injected fine, when it comes to the ReactiveCrudRepos, I am not having any luck on getting their instantiated object. What do I need to do to have the implementations created and injected?

Answer 1

As long as you use #SpringBootTest(classes = Service.class), the other beans are not loaded into the application context. The annotation element class of the annotation is described as:
The component classes to use for loading an ApplicationContext.
Remove the element and use the #SpringBootApplication as is:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = Service.class)
public class ServiceTest { /* code */ }
Remember, using this way is testing an application context completely different from what will be run on the production environment. It should be a last resort.
Moreover, avoid naming the interface Repository when there exists the Spring annotation #Repository itself. I would personally prefer:
#Repository
public interface ItemRepository extends ReactiveCrudRepository<Item, Integer> {
}
