The recent models are pretty great at this. They read the source code for e.g. a Python web application and use that to derive what the URLs should be. Then they fire up a localhost development server and write Playwright scripts to interact with those pages at the predicted URLs.
The vision models (Claude Opus 4.5, Gemini 3 Pro, GPT-5.2) can even take screenshots via Playwright and then "look at them" with their vision capabilities.
It's a lot of fun to watch. You can tell them to run Playwright not in headless mode at which point a Chrome window will pop up on your computer and you can see them interact with the site via it.
