Scala Integration Testing with Testcontainers and Docker Compose

Setting up reliable environments for integration testing can be a major bottleneck in backend development. This text-based course guides you through the process of isolating your Scala integration tests by managing external dependencies directly from your codebase. You will learn to eliminate flaky tests and manual environment setup by orchestrating real services programmatically. By the end of this course, you will be able to confidently configure, spin up, and tear down external resources during your test cycles, ensuring consistent test runs across different development environments and continuous integration pipelines. What you will learn: Understand the core concepts of integration testing and service isolation in Scala; Configure Docker Compose to manage multi-container testing environments; Implement Testcontainers-scala to programmatically control external services; Mock AWS cloud resources locally using LocalStack within your test suite; Apply modern Scala testing practices using popular libraries like Minitest or ScalaTest; Manage container lifecycles efficiently to optimize test execution times. This course starts with foundational testing concepts and containerization basics before moving into hands-on configuration patterns and advanced local cloud mocking. It is designed for beginner to intermediate Scala developers who want to improve their testing workflows, with no prior container orchestration experience required.
