AI-Powered Test Automation: How Playwright Agents Plan, Write, and Fix Tests for Us

# testing # qa # ai # playwright

There's a point in every QA engineer's journey when maintaining automated tests becomes harder than writing them. You fix one flaky selector, another breaks - a small refactor ripples through half the suite.

We've spent years making automation smarter with patterns, abstractions, and better reporting - but structure alone can't keep up with change.

Now, with Planner, Generator, and Healer, Playwright can analyze your UI, plan test cases, fix broken steps, and explain issues in plain English. We're entering a phase where AI acts like a test engineer that never sleeps - one that learns from every failure.

In this post, I'll show how I used Playwright Agents on a simple Dockerized Juice Shop app - how they plan, write, and fix tests on their own, and what that means for QA.

Setting the Stage: Starting with Structure

Before generating anything, I wanted the AI to understand my folder logic - a clean structure is half the battle in Playwright automation.

To help the Agent learn that structure, I first created the folders manually inside VS Code Insider - one for each part of the framework: components, fixtures, pages, selectors, tests, and utils. Once the structure was ready, I opened the workspace and prompted the Agent to explore it. From that point, every generated file automatically followed the same naming and placement pattern I had defined.
