# Web App Testing

Use this skill to interact with and test a local web application in a real browser.

## What it does
- Launches the app under Playwright and drives it like a user
- Verifies that frontend flows actually work
- Captures screenshots of the running UI
- Reads browser console logs to diagnose failures

## When to reach for it
When you need to confirm a change works in the real app — clicks, navigation, rendering — not just that unit tests pass.

Description

A toolkit for driving and testing local web applications with Playwright. It verifies frontend functionality, debugs UI behavior, captures browser screenshots, and surfaces browser console logs — useful for confirming a change works in a real browser rather than only in unit tests.
