Spring Boot on a Diet: A Leaner Spring Testing Cookbook

Frustrated by slow Spring Boot tests, or skipping integration tests because they're too slow? They don’t have to be! I’ll share recipes that make integration tests nearly as fast as unit tests. We’ll explore how to balance performance and reliability when testing HTTP clients, JSON serialization, transactions, messaging, and more, so you can speed up your tests without sacrificing accuracy. Don’t miss this session packed with practical solutions!
