Learn how to optimize Spring Boot test performance and memory usage in this conference talk that explores the inner workings of Spring's Integration Test Framework. Discover how Spring contexts are cached and reused across tests, and understand the challenges that arise in large-scale applications with multiple modules and heavy-weight components like TestContainers. Explore practical optimization strategies including test reordering and smart context closing logic to prevent out-of-memory failures and reduce execution time. Master techniques that can significantly improve both memory efficiency and test stability in enterprise Spring Boot applications through real-world examples and detailed implementation guidance.
