Couchbase Container does not work with Junit 5 and @Testcontainers

[hantsy]

I tried to use @TestContainers and @Container to bootstrap a Couchbase in a docker for testing purpose.

@SpringBootTest
@Testcontainers
@ActiveProfiles("test")
class PostRepositoryWithDynamicPropertiesTest {
    private static final String COUCHBASE_IMAGE_NAME = "couchbase";
    private static final String DEFAULT_IMAGE_NAME = "couchbase/server";
    private static final DockerImageName DEFAULT_IMAGE = DockerImageName.parse(COUCHBASE_IMAGE_NAME)
            .asCompatibleSubstituteFor(DEFAULT_IMAGE_NAME);

    @Container
    final static CouchbaseContainer couchbaseContainer = new CouchbaseContainer(DEFAULT_IMAGE)
            .withCredentials("Administrator", "password")
            .withBucket(new BucketDefinition("demo").withPrimaryIndex(true))
            .withStartupTimeout(Duration.ofSeconds(60));

    @DynamicPropertySource
    static void bindCouchbaseProperties(DynamicPropertyRegistry registry) {
        registry.add("spring.couchbase.connection-string", couchbaseContainer::getConnectionString);
        registry.add("spring.couchbase.username", couchbaseContainer::getUsername);
        registry.add("spring.couchbase.password", couchbaseContainer::getPassword);
        registry.add("spring.data.couchbase.bucket-name", () -> "demo");
    }

}

When running the application it always refused to connect.

com.couchbase.client.core.deps.io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: localhost/127.0.0.1:50392

I also used other database with testcontainers, others are not problematic.

And I use an Spring Boot initializer class to bootstrap it manually, it works.

@SpringBootTest
@ContextConfiguration(initializers = PostRepositoryTest.TestContainerInitializer.class)
@ActiveProfiles("test")
class PostRepositoryTest {

    static class TestContainerInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
        private static final String COUCHBASE_IMAGE_NAME = "couchbase";
        private static final String DEFAULT_IMAGE_NAME = "couchbase/server";
        private static final DockerImageName DEFAULT_IMAGE = DockerImageName.parse(COUCHBASE_IMAGE_NAME)
                .asCompatibleSubstituteFor(DEFAULT_IMAGE_NAME);

        @Override
        public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
            final CouchbaseContainer couchbaseContainer = new CouchbaseContainer(DEFAULT_IMAGE)
                    .withCredentials("Administrator", "password")
                    .withBucket(new BucketDefinition("demo").withPrimaryIndex(true))
                    .withStartupTimeout(Duration.ofSeconds(60));

            couchbaseContainer.start();

            configurableApplicationContext
                    .addApplicationListener((ApplicationListener<ContextClosedEvent>) event -> couchbaseContainer.stop());
            TestPropertyValues.of(
                            "spring.couchbase.connection-string=" + couchbaseContainer.getConnectionString(),
                            "spring.couchbase.username=" + couchbaseContainer.getUsername(),
                            "spring.couchbase.password=" + couchbaseContainer.getPassword(),
                            "spring.data.couchbase.bucket-name=demo"
                    )
                    .applyTo(configurableApplicationContext.getEnvironment());
        }
    }

}

Update: I found on the Github actions, sometime the later failed. And always one of them failed. I am not sure the reason. See the github actions log: https://github.com/hantsy/spring-reactive-sample/runs/4199996412?check_suite_focus=true

If I ran the tests one by one, it worked well. I guess there are some clean work not performed in the running tests that affects the further tests.

On Github actions, I have to add scripts to clean the Docker data and run them one by one to make sure it working. see: https://github.com/hantsy/spring-reactive-sample/blob/master/.github/workflows/boot-data-couchbase.yml#L31

  cd boot-data-couchbase
  mvn -q clean test -Dtest=PostRepositoryWithDynamicPropertiesTest
  docker rm docker ps -aq) -f
  mvn -q clean test -Dtest=PostRepositoryTest

Yeah, this indeed looks like some test pollution situation. Do you think you could provide a small reproducer project, so we can look at it in isolation?

@hantsy do you think it would be possible to enable DEBUG logging in your CI so that when there is a failure we can get more info from the SDK? Thanks!
