The document provides advice for testers on becoming a modern agile tester. It summarizes Xu Yi's personal journey from a structured "waterfall" model to adopting agile practices. It recommends that testers (1) keep testing but accept agile, (2) improve how they test through tools, practices, skills and teamwork, and (3) try new things like programming, coaching and innovating. Testers are advised to continuously learn and be willing to change.
