Toolkit for interacting with and testing local web applications using Playwright

webapp-testing is an agent skill from Composio's Awesome Claude Skills collection on GitHub. It tests local web applications with Playwright in Python: checking that the front end works, debugging interface behavior, taking browser screenshots and reading browser logs. It ships helper scripts, such as one that starts and stops servers. A skill is a SKILL.md file of instructions (sometimes with scripts and reference notes) that an AI agent loads only when a task calls for it, so the agent knows the steps to follow and what to avoid. It is free and open source.
