Azure Module

Note

This module is INCUBATING. While it is ready for use and operational in the current version of Testcontainers, it is possible that it may receive breaking changes in the future. See our contributing guidelines for more information on our incubating modules policy.

Testcontainers module for the Microsoft Azure's SDK.

Currently, the module supports CosmosDB emulator. In order to use it, you should use the following class:

Class	Container Image
CosmosDBEmulatorContainer	mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator

Usage example

CosmosDB

Start Azure CosmosDB Emulator during a test:

Starting a Azure CosmosDB Emulator container

public CosmosDBEmulatorContainer emulator = new CosmosDBEmulatorContainer(
    DockerImageName.parse("mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:latest")
);

Prepare KeyStore to use for SSL.

Building KeyStore from certificate within container

Path keyStoreFile = tempFolder.newFile("azure-cosmos-emulator.keystore").toPath();
KeyStore keyStore = emulator.buildNewKeyStore();
keyStore.store(new FileOutputStream(keyStoreFile.toFile()), emulator.getEmulatorKey().toCharArray());

Set system trust-store parameters to use already built KeyStore:

Set system trust-store parameters

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

Build Azure CosmosDB client:

Build Azure CosmosDB client

CosmosAsyncClient client = new CosmosClientBuilder()
    .gatewayMode()
    .endpointDiscoveryEnabled(false)
    .endpoint(emulator.getEmulatorEndpoint())
    .key(emulator.getEmulatorKey())
    .buildAsyncClient();

Test against the Emulator:

Testing against Azure CosmosDB Emulator container

CosmosDatabaseResponse databaseResponse = client.createDatabaseIfNotExists("Azure").block();
assertThat(databaseResponse.getStatusCode()).isEqualTo(201);
CosmosContainerResponse containerResponse = client
    .getDatabase("Azure")
    .createContainerIfNotExists("ServiceContainer", "/name")
    .block();
assertThat(containerResponse.getStatusCode()).isEqualTo(201);
