Frontend Nation 2026: How I Used AI to Fix Our E2E Test Architecture by Debbie O'Brien

What happens when your E2E tests pass in CI but fail locally? In this Frontend Nation 2026 talk, Debbie O'Brien, Platform Engineer – Applied AI at Zephyr Cloud, shares how she used AI to analyze 14,000 lines of Playwright test infrastructure, uncover hidden issues, and systematically improve the reliability of an end-to-end testing suite. Learn how a reusable AI-driven workflow helped identify problems across dozens of test files, implement 33 targeted improvements, and measure the impact with real before-and-after benchmarks. #AI #Playwright #Testing #E2ETesting #QualityEngineering #DebbieOBrien #ZephyrCloud #FrontendNation #FEN2026 🎟️ Join the waitlist for Frontend Nation 2027: https://frontendnation.com/ 💻 Stay up to date with Frontend Nation: LinkedIn:   / frontend-nation   X/Twitter: https://x.com/frontendnation Facebook: https://www.facebook.com/photo/?fbid=...
