New Technology

AI is inmiddels overal in softwareontwikkeling te vinden. Van code genereren tot documentatie schrijven, van workflows automatiseren tot agents die zelfstandig acties uitvoeren. Maar hoe houd je grip op tools die niet altijd hetzelfde antwoord geven? En wie is er uiteindelijk verantwoordelijk als AI daadwerkelijk iets gaat doen? Tijdens deze meetup duiken we in de praktische kant van AI in software engineering en test automation. Zoals altijd georganiseerd door deTesters, TestCoders en TechChamps, in ons kantoor in de Werkspoorkathedraal in Utrecht. Deze keer hebben we twee talks die mooi op elkaar aansluiten. Ghislain Gabriëlse laat zien hoe je AI skills kunt testen wanneer klassieke assertions niet meer genoeg zijn. Bert Jan Schrijver neemt ons mee in de bredere vraag wat AI agents betekenen voor software engineering, verantwoordelijkheid en controle. Twee talks, twee invalshoeken, maar allebei heel relevant voor iedereen die serieus bezig is met kwaliteit, test automation en de manier waarop AI ons vak verandert. **The Agent Who Tested Me: Behavioral Testing for AI Skills** Hoe test je tools die elke keer net een ander antwoord kunnen geven? Ghislain laat zien hoe zij AI skills testen met echte Copilot sessies, zonder alles weg te mocken. Want bij LLMs kun je niet simpelweg een assertEquals op de output zetten. Tenzij je van mega flaky tests houdt. In deze talk neemt hij je mee in een framework waarmee AI skills op verschillende niveaus worden gevalideerd. Van deterministische checks en een LLM Judge tot baseline vergelijkingen en variance analysis. Zo wordt niet alleen gekeken of een skill iets teruggeeft, maar ook of het antwoord klopt, waarde toevoegt en betrouwbaar genoeg is. Een praktische sessie over testen, CI en non determinisme voor iedereen die bezig is met AI, test automation of Copilot skills. **Ghislain Gabriëlse** Ghislain Gabriëlse is een ervaren Test Automation Engineer met ruim 11 jaar ervaring in testen en automatisering. Hij richt zich vooral op het ontwikkelen en inrichten van tools en frameworks die de developer experience verbeteren, zodat teams beter en efficiënter kunnen ontwikkelen en testen. **Software engineering in the age of AI agents: who’s in control?** Een AI verwijdert een production database en blijft vervolgens volhouden dat dit niet is gebeurd. Welkom in moderne software engineering. Generatieve AI wordt steeds vaker een echte samenwerkingspartner. Het schrijft code, past systemen aan en voert acties uit. Maar dat betekent niet automatisch dat het ook doet wat wij denken dat het doet. In deze presentatie neemt Bert Jan ons mee in wat er echt verandert. Niet alleen in hoe we code schrijven, maar vooral in hoe we controleren, begeleiden en verantwoordelijkheid nemen. De rol van engineers verschuift steeds meer van zelf bouwen naar richting geven, beoordelen en kritisch blijven kijken naar wat AI oplevert. Aan de hand van persoonlijke verhalen, inzichten uit de industrie, successen en mislukkingen laat Bert Jan zien hoe je verantwoord om kunt gaan met AI tools die zich razendsnel ontwikkelen. Want ook als je AI het werk laat doen, blijf jij verantwoordelijk voor de uitkomst. **Bert Jan Schrijver** Bert Jan Schrijver is CTO bij OpenValue en houdt zich bezig met Java, AI, software architectuur, Continuous Delivery en DevOps. Hij is Java Champion, JavaOne Rock Star speaker, winnaar van een Duke’s Choice Award en bestuurslid bij NLJUG, de Nederlandse Java User Group. Daarnaast deelt hij graag zijn kennis op conferenties, schrijft hij voor het Nederlandse Java Magazine en helpt hij bij Devoxx4Kids om kinderen te leren programmeren. **Doelgroep** Deze meetup is interessant voor testers, QA engineers, developers en iedereen die bezig is met kwaliteit in moderne software teams. Deze avond is **volledig in het Nederlands (Dutch spoken).** **Programma** 17:30 Ontvangst en eten 18:30 The Agent Who Tested Me: Behavioral Testing for AI Skills 19:30 Korte pauze 19:45 Software engineering in the age of AI agents: who’s in control? 20:45 Q&A en discussie 21:00 Afsluiting met een borrel

Hi people! Tonight we'll play boardgames at Café Lombok, a vibrant place in the Vleutenseweg 228 ( https://maps.app.goo.gl/1uKfqXEF1CZA6qX96 ). Feel free to bring your favorite game and enjoy it with us if you want! This meetup is expected to start at 21:00 and it will finish at 23:00 pm. We will give 30 minutes of courtesy for those who can't be there at 21:00. After 21:30 you can either join the game by teaming up with another player or wait until the round is over and we start a new one (depending on the rules of the game). We do this to protect the scored points and the progress we make.

I’m putting together a small hike trip weekend in Hoorneboegse heide in Hilversum, the idea is to come with a few people who want to step out of their routine, spend time in nature, and meet others in a relaxed way. This is not a tour or a structured retreat. The idea is simple step out of your comfort and everyday life to reconnect with nature and with each other. We will – explore the beautiful nature – share a few moments together – and keep things easy and natural There will be time together (walks and sunset). Group size will be small (around 2- 4 people), to keep it comfortable and personal. This Meetup is to connect people who are interested in real and human connection If this resonates, feel free to join and I’ll share more details 🙂
