Many organizations enforce rules like "minimum 85% code coverage required to deploy" to improve code quality. Yet, even with extensive unit tests that satisfy these quality gates, teams often encounter critical issues post-deployment. Why does this happen?

Modern applications rely on diverse technologies—SQL/NoSQL databases, message brokers, and more. Unit tests with mocks or in-memory services might make the code look solid, but they fail to ensure your application behaves correctly with the real services it depends on in production.

Testcontainers is a library that lets you bootstrap real, production-like dependencies for your tests using Docker containers. With Testcontainers, you can test your application against real databases, message brokers, etc bringing the same testing experience both in local and CI pipelines.

In this session, you'll learn:

* How to test your application using SQL/NoSQL databases and message brokers with Testcontainers.
* How to test AWS service integrations using LocalStack and Testcontainers.
* How Testcontainers seamless integration with Spring Boot improve your local development experience.
