Many applications rely on cloud solutions like AWS, Azure, and GCP. Testing such applications could be a nightmare of spare cloud accounts or never-ending environment setups. Thanks to Testcontainers, we can run all the necessary services locally and even more programmatically control their configuration and lifecycle! It means you can improve your development feedback loop locally and test your cloud-native applications without spending a penny. In this demo-heavy session, we’ll go over typical use cases cloud-native app developers struggle to test effectively, and look at how Testcontainers features enable working with S3, DynamoDB, Lambdas, Google Spanner, and others. Testing your cloud-native applications with Localstack and GCloud modules has never been this easy and reliable.
