Dockerized services are an excellent tool for creating repeatable, isolated environments ideal for integration tests. In this session, we'll look at the Testcontainers libraries which provide flexible and intuitive API for programmatically controlling lifecycle of your service dependencies in Docker containers. Running databases, Kafka, Elasticsearch, and even cloud technologies, straight from your test code ensures environment config is always up-to-date and consistent during local development and in CI pipelines.You’ll learn everything necessary to start adding powerful integration tests to your codebase without the headache of managing external service dependencies manually!
