Thanks to everyone who attended my talk with @shelajev.bsky.social at @javazone.bsky.social yesterday! We hope you now feel confident making sure your #AI #Java apps are always getting better! The slides from our session are available at speakerdeck.com/edeandrea/ja...
Nice surprise from @javazone.bsky.social today! Looks like I'll be joining @shelajev.bsky.social on stage!
🧪 "But how do you test AI apps?" Watch Java Champions @shelajev.bsky.social & @ericdeandrea.dev show how to test non-deterministic AI applications using Testcontainers, LangChain4j, Quarkus & Ollama. Practical solutions, no excuses! 🎥 www.youtube.com/watch?v=C7-X... #Jfokus #AIdev #Testing
Non-deterministic? No problem! You can test it! by Eric Deandrea & Oleg Šelajev
Testing is hard, which is why developers tend to avoid it. Testing non-deterministic things is even harder, which is unfortunate, since we're all writing AI-...

Full room for @ericdeandrea.dev and @shelajev.bsky.social's session about testing non-deterministic systems at #Jfokus . Seems like many developers are curious how to actually test the results of LLMs 🥲. @jfokus.se #AI
All Hands-on lab are fully booked this morning! #Quantum with Gavin King, Java for Cloud with @rustam.no, Testcontainers with @shelajev.bsky.social and LangChain4j with @kevindubois.com, @danieloh30.bsky.social, @geoand86.bsky.social and @ericdeandrea.dev
Attending @jfokus.se and looking for a good session? Join @shelajev.bsky.social and myself tomorrow Feb 4 at 11:00 in Room C1 to learn how to #test #ai and #nondeterministic systems! @quarkus.io #testcontainers #docker https://buff.ly/413kyOr
Our Dev Practices Track Team marks the halfway point of our Team series. Time flies when you’re meeting exceptional people: @mkheck.bsky.social @shelajev.bsky.social @piotrprz.bsky.social Cora Iberkleid & Jamie Chapman. The deadline to submit talks is Jan 10 ➡️ devoxxuk25.cfp.dev/#/
Due to a happy coincidence, I managed to get into the #DingGukesh Fide chess world championship match! It feels pretty surreal to see a part of chess history in the making!
Super excited to be presenting at @jfokus.se this year! @shelajev.bsky.social and I will be talking about how to test non-deterministic things!
