OpenRewrite in a Nutshell: Scaling Upgrades with Practical Insights
Schnelle Upgrades, einfache Rezepte:

• Was ist OpenRewrite? Kurz & knackig.
• Rezepte anwenden: Composite Recipes, dryRun vs. run
• Tech-Upgrades: Wenig Downtime, klare Nachvollziehbarkeit (z.B. EAP-8)
• Lesende Rezepte: Code-Analyse leicht gemacht
• Rezepte schreiben: LSTs, Visitors, Praxisbeispiel
• Rezepte wiederverwenden: EAP-8, Quarkus, Spring Microservices

Ideal für effiziente, transparente Software-Upgrades.

how John started to like TDD (instead of hating it)
Let me share a story about how John (a developer like any other) started to understand (and enjoy) writing Tests before the Production code.

We've all felt an inevitable "tedium" when writing tests, haven't we? If it's boring, if it's complicated or unnecessary? Isn't it? John thought so too, and, as much as he had heard about writing tests before production code, he had never managed to put it into practice, and even when he had tried, John had become even more frustrated at not understanding how to put it into practice outside of a few examples katas 🤷‍♂️

Listen to this story in which I will explain how John went from not understanding Test Driven Development (TDD) to being passionate about it... so much that now he doesn't want to work any other way 😅 ! He must have found some benefits in practising it, right? He says he has more advantages than working in any other way (e.g., you'll find defects earlier, you'll have a faster feedback loop or your code will be easier to refactor), but I'd better explain it to you in the session, right? Ah! And if you think everything will be theoretical, no! Get ready to see code examples with Spring Boot.

PS: Think of John as a random person, as if he was even the speaker of this talk 😉 !
