Testing distributed systems is not about more tests — it’s about better signals. I gave this talk at InfoQ Dev Summit Boston sharing practical strategies for realistic, fast, and reliable testing in complex architectures. 🎥 Watch the talk or read its transcript.

I’ll be speaking at @jchampionsconf.bsky.social 🎉 🎤 Test Smarter, Not Harder - practical testing strategies for complex distributed systems. 🗓 Jan 26 · 18:00 CET 🔗 jchampionsconf.com 🎟 www.eventbrite.com/e/jchampions... 🎥 www.youtube.com/@JChampionsC...

Hard assertions = fast feedback ✅ But when one failure hides others, you lose valuable insight. 😥 Here’s how to use custom soft assertions with AssertJ to make your tests graceful, readable, and thorough: eliasnogueira.com/assert-with-... #java #testing #quality

Day 1 wearing with glasses🥸: I can see everything in full HD now!

Want cleaner, more expressive tests in Java? ✅ Avoid endless try-catch ✅ Group failures with elegance ✅ Use AssertJ the right way Soft assertions can raise your testing game without clutter. Learn how: eliasnogueira.com/assert-with-... #java #quality #test #qualityengineering

Testing Architecture isn’t just about big decisions — it’s about repeatable, proven patterns. I shared 3 design patterns to guide architectural decisions, like BaseTest, Fluent Interface, Factory, Data Generation, and more. github.com/eliasnogueir... #testing #java

No, because if I have a library that is feature complete, this would force me to create a release per year, because people will think the library is outdated. One of my customers uses that to force his customers to update to the newest version.

I like CalVer whenever versions become a point of discussion; it's hard to argue to continue to use 2019.08 today, whereas 1.5 hides that nuance of using outdated technology. Breaking changes with SemVer are a solved problem when you use the right technology! ;)

Today I heard from a coworker that SemVer is old and outdated and CalVer should be used because is more modern. What do you think: is SemVer really outdated and has no value anymore?

I'm going to Prague this Friday. Any local tips for me?
