Learn Testcontainers with Java

Write fast, reliable integration tests using real containers

Modern Integration Testing

Reliable integration tests shouldn’t depend on fragile local setups or unrealistic in-memory replacements. 

This material will explore how to use Testcontainers to run real databases, message brokers, caches, and cloud services in Docker. The goal is to make your tests more reliable, reproducible, and production-ready.

Starting with the core concepts, we’ll build integration tests for PostgreSQL, MongoDB, Kafka, Redis, MockServer, before exploring modern Spring Boot features such as @ServiceConnection, development-time containers, and container reuse.

Actual practice through a Java project – definitely the best way to understand Testcontainers

The essential guide to building reliable integration tests with Testcontainers. The 4 modules build practical skills step by step: from Testcontainers fundamentals and container lifecycle management, to testing databases, messaging, caching and cloud services.

Everything you need to understand integration testing with Testcontainers.
