Compatibilidad de Spring Cloud con Azure para Testcontainers

En este artículo se describe cómo integrar Spring Cloud Azure con Testcontainers para escribir pruebas de integración eficaces para las aplicaciones.

Testcontainer es un marco de código abierto para proporcionar instancias de origen, ligeras de bases de datos, agentes de mensajes, exploradores web o casi cualquier cosa que pueda ejecutarse en un contenedor de Docker. Se integra con JUnit, lo que le permite escribir una clase de prueba que pueda iniciar un contenedor antes de que se ejecute cualquiera de las pruebas. Testcontainer es especialmente útil para escribir pruebas de integración que hablan con un servicio back-end real.

La biblioteca de spring-cloud-azure-testcontainers ahora admite pruebas de integración para los siguientes servicios de Azure:

• de Azure Cosmos DB
• de Azure Blob Storage
• de Azure Queue Storage
• Azure Event Hubs
• Azure Service Bus

Conexiones de servicio

Una conexión de servicio es una conexión a cualquier servicio remoto. La configuración automática de Spring Boot puede consumir los detalles de una conexión de servicio y usarlas para establecer una conexión a un servicio remoto. Al hacerlo, los detalles de conexión tienen prioridad sobre las propiedades de configuración relacionadas con la conexión.

Al usar Testcontainers, puede crear automáticamente detalles de conexión para un servicio que se ejecuta en un contenedor anotando el campo contenedor en la clase de prueba.

xxxContainerConnectionDetailsFactory Las clases se registran con spring.factories. Estas factorías crean un bean de ConnectionDetails en función de una subclase Container específica o el nombre de la imagen de Docker.

En la tabla siguiente se proporciona información sobre las clases de generador de detalles de conexión admitidas en el archivo JAR de spring-cloud-azure-testcontainers:

Clase de generador de detalles de conexión	Bean de detalles de conexión
CosmosContainerConnectionDetailsFactory	AzureCosmosConnectionDetails
StorageBlobContainerConnectionDetailsFactory	AzureStorageBlobConnectionDetails
StorageQueueContainerConnectionDetailsFactory	AzureStorageQueueConnectionDetails
EventHubsContainerConnectionDetailsFactory	AzureEventHubsConnectionDetails
ServiceBusContainerConnectionDetailsFactory	AzureServiceBusConnectionDetails

Uso de Testcontainers

En el ejemplo de código siguiente se muestra el uso básico de Testcontainers:

@SpringBootTest(classes = CosmosTestcontainersTest.class)
@Testcontainers
@ExtendWith(SpringExtension.class)
@ImportAutoConfiguration(classes = { AzureGlobalPropertiesAutoConfiguration.class, AzureCosmosAutoConfiguration.class})
public class CosmosTestcontainersTest {

    @TempDir
    private static File tempFolder;

    @Autowired
    private CosmosClient client;

    @Container
    @ServiceConnection
    static CosmosDBEmulatorContainer cosmos = new CosmosDBEmulatorContainer(
        DockerImageName.parse("mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:latest"))
                .waitingFor(Wait.forHttps("/_explorer/emulator.pem").forStatusCode(200).allowInsecure())
                .withStartupTimeout(Duration.ofMinutes(3));

    @BeforeAll
    public static void setup() throws IOException, CertificateException, KeyStoreException, NoSuchAlgorithmException {
        Path keyStoreFile = new File(tempFolder, "azure-cosmos-emulator.keystore").toPath();
        KeyStore keyStore = cosmos.buildNewKeyStore();
        try (var out = Files.newOutputStream(keyStoreFile.toFile().toPath())) {
            keyStore.store(out, cosmos.getEmulatorKey().toCharArray());
        }

        System.setProperty("javax.net.ssl.trustStore", keyStoreFile.toString());
        System.setProperty("javax.net.ssl.trustStorePassword", cosmos.getEmulatorKey());
        System.setProperty("javax.net.ssl.trustStoreType", "PKCS12");
    }

    @Test
    public void test() {
        CosmosDatabaseResponse databaseResponse = client.createDatabaseIfNotExists("Azure");
        assertThat(databaseResponse.getStatusCode()).isEqualTo(201);
        CosmosContainerResponse containerResponse = client
            .getDatabase("Azure")
            .createContainerIfNotExists("ServiceContainer", "/name");
        assertThat(containerResponse.getStatusCode()).isEqualTo(201);
    }

}

Para usar CosmosDBEmulatorContainer, debe preparar un KeyStore para TLS/SSL. Para más información, consulte módulo de Azure de Cosmos DB en la documentación de Testcontainers. Con @ServiceConnection, esta configuración permite que los frijoles relacionados con Cosmos DB de la aplicación se comuniquen con Cosmos DB que se ejecutan dentro del contenedor de Docker administrado por Testcontainers. Esta configuración define automáticamente un AzureCosmosConnectionDetails bean, que la configuración automática de Cosmos DB usa para invalidar las propiedades de configuración relacionadas con la conexión.

blob Storage

@SpringJUnitConfig
@Testcontainers
class StorageBlobTestcontainersTest {
    @Container
    @ServiceConnection
    private static final GenericContainer<?> AZURITE_CONTAINER = new GenericContainer<>(
            "mcr.microsoft.com/azure-storage/azurite:latest")
            .withExposedPorts(10000)
            .withCommand("azurite --skipApiVersionCheck && azurite -l /data --blobHost 0.0.0.0 --queueHost 0.0.0.0 --tableHost 0.0.0.0");

    @Value("azure-blob://testcontainers/message.txt")
    private Resource blobFile;

    @Test
    void test() throws IOException {
        String originalContent = "Hello World!";
        try (OutputStream os = ((WritableResource) this.blobFile).getOutputStream()) {
            os.write(originalContent.getBytes());
        }
        String resultContent = StreamUtils.copyToString(this.blobFile.getInputStream(), Charset.defaultCharset());
        assertThat(resultContent).isEqualTo(originalContent);
    }

    @Configuration(proxyBeanMethods = false)
    @ImportAutoConfiguration(classes = {AzureGlobalPropertiesAutoConfiguration.class, AzureStorageBlobAutoConfiguration.class, AzureStorageBlobResourceAutoConfiguration.class})
    static class Config {
    }
}

Con @ServiceConnection, esta configuración permite que los beans relacionados con blobs de la aplicación se comuniquen con Blob Storage que se ejecuta dentro del contenedor de Docker administrado por Testcontainers. Esta configuración define automáticamente un AzureStorageBlobConnectionDetails bean, que la configuración automática de Blob Storage usa para invalidar las propiedades de configuración relacionadas con la conexión.

Queue Storage

@SpringBootTest(classes = StorageQueueTestcontainersTest.class)
@Testcontainers
@TestPropertySource(properties = "spring.cloud.azure.storage.queue.queue-name=devstoreaccount1/tc-queue")
@ExtendWith(SpringExtension.class)
@ImportAutoConfiguration(classes = { AzureGlobalPropertiesAutoConfiguration.class, AzureStorageQueueAutoConfiguration.class})
public class StorageQueueTestcontainersTest {

    @Container
    @ServiceConnection
    private static final GenericContainer<?> AZURITE_CONTAINER = new GenericContainer<>(
        "mcr.microsoft.com/azure-storage/azurite:latest")
        .withExposedPorts(10001)
        .withCommand("azurite-queue", "--queueHost", "0.0.0.0", "--skipApiVersionCheck");

    @Autowired
    private QueueClient queueClient;

    @BeforeAll
    public static void setup() {
        AZURITE_CONTAINER.start();
    }

    @Test
    public void test() {
        String message = "Hello World!";
        this.queueClient.create();
        this.queueClient.sendMessage(message);
        assertThat(this.queueClient.receiveMessage().getBody().toString()).isEqualTo(message);
    }

}

Con @ServiceConnection, esta configuración permite que los beans relacionados con la cola de la aplicación se comuniquen con Queue Storage que se ejecuta dentro del contenedor de Docker administrado por Testcontainers. Esta configuración define automáticamente un AzureStorageQueueConnectionDetails bean, que la configuración automática de Queue Storage usa para invalidar las propiedades de configuración relacionadas con la conexión.

            .withNetwork(NETWORK)

    @Autowired

    @Autowired

    @Test
    void connectionDetailsShouldBeProvidedByFactory() {

        assertThat(connectionDetails.getConnectionString())

    @ImportAutoConfiguration(classes = {AzureGlobalPropertiesAutoConfiguration.class,
            AzureEventHubsAutoConfiguration.class})
    static class Config {

    }
}

Con @ServiceConnection, esta configuración permite que los beans relacionados de la aplicación se comuniquen con Event Hubs que se ejecutan dentro del contenedor de Docker administrado por Testcontainers.
