Slack Shows AI Agents Can Replace Scripts in UI Tests—But at $15‑30 Per Run
Slack’s engineering team ran 200+ AI‑driven end‑to‑end tests using Playwright and found agents can achieve UI goals without fixed scripts, automatically adapting to UI changes. Each run costs $15‑30 and takes over ten minutes, so the approach is reliable but pricey, fitting best as a complementary, high‑value exploratory layer alongside traditional deterministic tests.
