Clarify documentation on importing Testcontainer declarations and using @ServiceConnection or @DynamicPropertySource #35629
Description
Hi
We tried to use Spring Boot & TestContainers integration added in Spring Boot 3.1.0.
We used example from the reference documentation:
public interface MyContainers {
@Container
MongoDBContainer mongoContainer = new MongoDBContainer("mongo:5.0");
@Container
Neo4jContainer<?> neo4jContainer = new Neo4jContainer<>("neo4j:5");
}
So we created an interface with our container declaration:
public interface ProjectContainers {
@Container
GenericContainer<?> mysql = new MySQLContainer("mysql:8");
}
Then we created class-configuration:
@TestConfiguration(proxyBeanMethods = false)
@ImportTestcontainers(ProjectContainers.class)
public class ContainerConfiguration {
}
and finally our integration test:
@SpringBootTest(classes = ContainerConfiguration.class)
@Testcontainers
public class OrderServiceTest {
@Autowired
OrderService orderService;
@Test
void save_success() {
Order order = new Order();
orderService.save(order);
}
However our test failed with exception:
