Testcontainers için Spring Cloud Azure desteği

Bu makalede, uygulamalarınız için etkili tümleştirme testleri yazmak için Spring Cloud Azure'ı Testcontainers ile tümleştirme açıklanmaktadır.

Testcontainer ; veritabanlarının, ileti aracılarının, web tarayıcılarının veya docker kapsayıcısında çalıştırabileceğiniz hemen hemen her şeyin basit örneklerini sağlamaya yönelik açık kaynak bir çerçevedir. JUnit ile tümleştirildiğinden, testlerden herhangi biri çalışmadan önce kapsayıcı başlatabilecek bir test sınıfı yazmanızı sağlar. Testcontainer, gerçek bir arka uç hizmetiyle konuşan tümleştirme testleri yazmak için özellikle yararlıdır.

spring-cloud-azure-testcontainers kitaplığı artık aşağıdaki Azure hizmetleri için tümleştirme testini destekliyor:

• Azure Cosmos DB
• Azure Blob Depolama
• Azure Kuyruk Depolama
• Azure Event Hubs
• Azure Service Bus

Hizmet bağlantıları

Hizmet bağlantısı, herhangi bir uzak hizmete bağlantıdır. Spring Boot'un otomatik yapılandırması, bir hizmet bağlantısının ayrıntılarını tüketebilir ve bunları kullanarak uzak bir hizmete bağlantı kurabilir. Bunu yaparken bağlantı ayrıntıları, bağlantıyla ilgili yapılandırma özelliklerine göre önceliklidir.

Testcontainers kullandığınızda, test sınıfındaki kapsayıcı alanına ek açıklama ekleyerek kapsayıcıda çalışan bir hizmet için bağlantı ayrıntılarını otomatik olarak oluşturabilirsiniz.

xxxContainerConnectionDetailsFactory sınıfları ile spring.factorieskaydedilir. Bu fabrikalar, belirli bir ConnectionDetails alt sınıfını veya Docker görüntü adını temel alan bir Container çekirdeği oluşturur.

Aşağıdaki tabloda, spring-cloud-azure-testcontainers JAR'da desteklenen bağlantı ayrıntıları fabrika sınıfları hakkında bilgi sağlanır:

Bağlantı ayrıntıları fabrika sınıfı	Bağlantı ayrıntıları çekirdeği
CosmosContainerConnectionDetailsFactory	AzureCosmosConnectionDetails
StorageBlobContainerConnectionDetailsFactory	AzureStorageBlobConnectionDetails
StorageQueueContainerConnectionDetailsFactory	AzureStorageQueueConnectionDetails
EventHubsContainerConnectionDetailsFactory	AzureEventHubsConnectionDetails
ServiceBusContainerConnectionDetailsFactory	AzureServiceBusConnectionDetails

Testcontainers kullanma

Aşağıdaki kod örneği, Testcontainers'ın temel kullanımını gösterir:

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

        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

}
