Integration test problem using test containers and docker “Caused by: java.lang.NullPointerException: containerId was not specified”

Question

I am super new to testcontainers . I am not even sure what I am trying to do make any sense or if there is a better approach for it.

Goal: Write an integration test for my MongoDb Repository. I am using Docker, Maven. Jdk11, Spring Boot 2.

My parent test class

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = {PostServiceApplication.class},
        properties = "spring.cloud.config.enabled:true",
        webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public abstract class AbstractIntegrationTest {

    private static final String MONGO_CONTAINER = "mongo:3.1.5";
    private static final Integer MONGO_PORT = 27017;
    private static final int CONFIG_SERVICE_PORT = 8888;

    @ClassRule
    public static GenericContainer mongo = new GenericContainer(MONGO_CONTAINER).withExposedPorts(MONGO_PORT);

    @ClassRule
    public static DockerComposeContainer configService =
            new DockerComposeContainer(new File("src/test/resources/configservice/docker-compose.yml"))
                    .withExposedService("ConfigService", CONFIG_SERVICE_PORT);


}

ConfigService is basically the SpringCloud configuration service which is a dependency to the service under the test.

My docker-compse.yaml

configservice:
  image: ponte/maven-3.5.4-jdk-11-slim-non-root
  ports:
    - "8888:8888"
  volumes:
    - "~/.m2/repository/app/configservice/configservice/0.0.1-SNAPSHOT/configservice-0.0.1-SNAPSHOT.jar:/configservice.jar"
  environment:
    - JAVA_OPTS=""
  hostname: "configservice"
  entrypoint: [ "sh", "-c", "java $JAVA_OPTS -jar /configservice.jar" ]

My test class

public class RepoTest extends AbstractIntegrationTest {

    @Autowired
    private MongoRepo repo;


    @Test
    public void test1() {
        assertNotNull(panoramaPostRepo);

        var post = Post.builder()
                .originalFileName("somefile.jpg")
                .dimension(new Dimension(1200, 480))
                .size(23000L)
                .uploadTime(ZonedDateTime.now())
                .build();


        var savedPost = repo.save(post);
        assertNotNull(savedPost);
        assertNotNull(savedPost.getId());
    }
}

I am getting the following error:

I also like to know is there any enhancement on what I am doing?

Answer 1

In your docker-compose.yaml, you have configservice , but later in the code: .withExposedService("ConfigService", ...) .

It is case sensitive.
