Java & Spring Boot Integration Testing with Testcontainers: Databases, Kafka, CI/CD

Testcontainers and Spring Boot: Real-World Integration Testing for Modern Java Applications
Master integration testing using Docker containers for databases, messaging systems, external APIs, and CI/CD pipelines.

Tired of unreliable integration tests that break in production? In this course, you will learn to replace brittle mocks with real containerized services using Testcontainers — the powerful Java library trusted by top developers for production-like integration testing.

You will build Spring Boot applications tested against real instances of PostgreSQL, Kafka, MongoDB, Redis, and more — all running inside isolated Docker containers.

Key Skills You Will Master:

Testcontainers Core (JUnit 5 and Spring Boot 3.1+)

• Start containers easily using @Container and @Testcontainers annotations

• Choose between GenericContainer and specialized containers like PostgreSQLContainer

• Utilize Spring Boot 3.1’s @ServiceConnection for automatic container configuration

Database Integration Testing

• Test database migrations with Flyway and Liquibase inside real PostgreSQL/MySQL containers

• Solve common issues like connection pooling, transaction isolation, and schema versioning

Messaging Systems Integration Testing

• Validate Kafka, RabbitMQ, ActiveMQ, and IBM MQ messaging flows using real message brokers

• Test consumer retries, dead-letter queues, and serialization logic

CI/CD Integration Testing

• Speed up pipelines by reusing containers with the Singleton pattern

• Integrate Testcontainers into GitHub Actions, GitLab CI, and CircleCI workflows

• Generate detailed test reports with Maven Surefire and Failsafe plugins

Advanced Testing Scenarios

• Test MongoDB queries and Redis caching inside containers

• Run Selenium-based UI tests inside Dockerized Chrome/Firefox browsers

• Mock external APIs using WireMock and MockServer in Testcontainers environments

Why This Course Works:

For Developers:

• Fix "works on my machine" bugs with real integration environments

• Reduce test flakiness by 60–70 percent compared to mock-based tests

• Learn best practices used by top Java teams in production systems

For Tech Leads and Architects:

• Standardize testing strategies across microservices and monolithic applications

• Cut CI/CD build times and cloud infrastructure costs with smarter container management

Prerequisites:

• Java and Spring Boot basic experience

• Familiarity with Docker (running containers)

Learn to design scalable, reliable integration tests that mirror production behavior — and gain confidence in your Spring Boot deployments.
