If you're unsure whether you're qualified to attend\, please get in touch.\n\nThis event is being held at Tokyo In novation Base (TiB). When attending it\, you'll also need to complete the free registration process with TiB if you have not already done so. You are strongly encouraged to complete this in advance\, as otherwise you'll need to complete it on site before you're allowed into the venue.\n\nAge nda\n\n18:30 〜 19:00 Doors open\n\nEnjoy talking with the other partici pants before the presentations begin. Drinks and a light meal will be pro vided by TokyoDev.\n\n19:00 〜 19:05 Opening - Paul McMahon \n\nWe'll ki ck things off by welcoming everyone and giving a short introduction of th e event.\n\n19:05 〜 19:30 ​No Scripts\, No Problem: Test automation with LLMs — Marc Lihan\n\nThis presentation explores how we rewrote tes t automation with LLMs. Traditional native and Appium frameworks offered limited coverage and required high maintenance\, so we turned to LLMs to determine how to perform user behaviors in testing.\n\nUsing this approac h\, our Test Automation Regression System (TARS) achieved 60% coverage in three months with almost no maintenance. Early versions faced hallucinat ions and automation errors\, resulting in only a 45% accuracy. Through pr ompt tuning\, experimentation\, and the addition of an Auditor agent\, we raised coverage to 95% and accuracy to 80%.\n\nAbout Marc Lihan (QA Engi neering Manager at SmartNews)\n\nMarc Lihan graduated from Waseda Univers ity and started his career at NEC in Tokyo\, where he witnessed the March 11 earthquake. He then relocated to Taiwan to work at HTC and LINE\, and later returned to Tokyo as an Engineering Manager overseeing QA at Smart News.\n\n19:40 〜 20:05 Multi-Environment Testing for Critical Systems — Marius-Mihail Gurgu\n\nWhen deploying software for critical systems in fields like robotics or fintech\, relying on a single staging environm ent for testing rarely provides sufficient reliability. This talk explore s the unique QA lifecycle that supports such systems\, emphasizing the la yered safety nets that protect both users and infrastructure. From simula tion environments to controlled staging setups and finally on-site valida tion\, each phase is designed to catch issues before they escalate.\n\nEq ually important is the discipline of balancing thorough testing with deve lopment speed—a crucial requirement for any software project where dela ys can ripple across teams and impact delivery. The talk also covers how QA professionals navigate this tension\, optimizing test coverage without compromising velocity.\n\nMarius-Mihail Gurgu (QA Engineer @ KOMOJU)\n\n I'm a QA engineer with experience in robotics and fintech systems\, apply ing what I learned from\nacademic research in autonomous drones to real-w orld testing. With a background in embedded\nsystems and dual MSc degrees \, I build testing frameworks to ensure reliability in complex\, real-\nt ime environments.\n\n20:05 〜 21:00 Open Networking\n\nDiscuss the prese ntation or anything else with the other attendees.\n\nWant to speak at a future event?\n\nWe're looking for speakers. You can find more details an d submit a proposal here.\n\nAbout TokyoDev\n\nTokyoDev's job board is fi lled with software developer positions at Japanese companies whose engine ering team’s primary language is English. From the big companies you’ ve already heard of\, to smaller up-and-coming startups\, our positions o ffer you the chance to live in Japan but work in an international environ ment.\n\nCode of Conduct\n\nAll attendees\, speakers\, sponsors and volun teers at our event are required to agree with the following code of condu ct. Organisers will enforce this code throughout the event.
