Philip Riecks | The Need for Speed: Cut Your Spring Boot Test Suite Duration by 70%

Java, Spring Boot, Spring Framework

Your Spring Boot test suite is a time thief. Every context reload, every unnecessary restart, every @DirtiesContext annotation is stealing precious minutes from your development flow. But what if those 20-minute test runs could shrink to just 6 minutes?

This session reveals the game-changing power of Spring's TestContext caching - a feature hiding in plain sight. We'll dissect how Spring decides to reuse or rebuild application contexts, expose the silent performance killers in your test suite, and demonstrate proven strategies that deliver dramatic speed improvements.

Through hands-on examples, you'll discover why @MockBean might be your worst enemy, how test execution order affects performance, and which configuration patterns maximize context reuse. We'll benchmark real applications, showing exactly where those 70% gains come from.

Stop accepting slow tests as "just the way it is." Leave with a concrete action plan to accelerate your test suite today - no new frameworks, no rewrites, just smarter
