What problem does it solve?
Manually testing local web applications, debugging UI behavior, and capturing browser state is time-consuming and prone to human error, especially for dynamic apps with JavaScript-rendered content.
Core Features & Use Cases
- Automated Browser Testing: Programmatically test frontend functionality including page navigation, form submissions, and interactive element behavior.
- UI Debugging & Inspection: Capture full-page screenshots, inspect rendered DOM, and monitor console logs to identify layout issues or JavaScript errors.
- Use Case: For example, when developing a local task management app, use this skill to automatically verify that adding a new task updates the UI correctly, capture a screenshot of the updated task list, and check for any console errors during the process.
Quick Start
Use the webapp-testing skill to run a Playwright script that navigates to your local web app at http://localhost:3000, waits for the page to fully load, takes a full-page screenshot, and confirms the page title matches your app's name.
