Playwright at Scale: Run 500 Tests in Minutes with Oliver Stenbom

Is your Playwright suite slowing you down instead of speeding you up? In this episode, Oliver Stenbom, cofounder of Endform, shares what really happens when teams try to scale Playwright from a handful of tests to hundreds, and why AI alone won’t fix unreliable tests.

You’ll discover why most flaky tests point to real problems in your application, how parallel test runs can expose performance limits you didn’t know you had, and why deterministic tests written as code are still a reviewable artifact worth owning in the age of AI agents.

Oliver also demos how an AI agent can explore a feature, then turn that session into a durable Playwright test using fixtures. He runs that test 100 times in parallel to surface a real race condition, then uses MCP and OpenTelemetry traces to let an agent diagnose the root cause.

Plus, hear how Lovable scaled from 12 to roughly 300 Playwright tests running in under two minutes on every pull request, how test quarantining keeps CI pipelines moving, and the single most important step to take this week: get serious about test isolation.

Whether you’re a QA engineer, automation engineer, or engineering leader, this episode will help you build a Playwright suite your team can actually trust.
