The Evolution of Software Testing

From Click to Code to Conversation; the next era of software testing is here Every team knows the moment: one small UI change, and half your test suite turns red. For decades we've built more sophisticated ways to verify software, yet our tests stay brittle — bound to selectors and timing instead of intent. This book tells the story of how that's finally changing.

What you'll learn The Evolution of Software Testing traces the craft through three eras — from manual testing , to coded automation , to the emerging world of agentic AI — with a sharp focus on the hardest arena of all: the user interface. You'll see clearly why traditional automation breaks, what agentic testing does differently, and how to put it to work.

At its heart is a practical, framework-agnostic pattern the authors call Tests as Prompts — expressing tests as natural-language intent that an AI agent interprets at runtime. The result is testing that adapts when the UI changes, reads like plain English, and can be written by anyone on the team.

Who it's for QA engineers, developers who write tests, and engineering leaders deciding where to invest next. Whether you're maintaining a legacy suite or building your first AI-driven tests, you'll come away with a clear map of where testing has been — and where it's going.

Written by two practitioners who have lived every experience firsthand.
