What is the best way to handle asynchronous elements?

The skill provides patterns for using explicit waits, such as 'waitForSelector', to ensure elements are visible and stable before interaction.

How can I view errors that happen inside the browser?

You can use the built-in console log inspection pattern to pipe browser logs directly into your terminal for real-time debugging.

Do I need to install Playwright manually to use this skill?

No, the webapp-testing skill is designed to automatically install Playwright if it is not already present on your system.

Can I test production websites or only local ones?

While optimized for local development environments, this skill can interact with any accessible URL, including live production sites.

Does this skill support mobile application testing?

It supports testing responsive web designs across different viewports, but it is not intended for native mobile app testing.

Security & Testing

Automates browser-based testing and debugging for local web applications using Playwright automation.

About

This skill provides a comprehensive toolkit for interacting with and validating local web applications through Playwright automation. It enables developers to perform end-to-end testing, verify complex UI behaviors, capture screenshots for visual debugging, and inspect browser console logs directly within the Claude Code environment. Whether you are validating form submissions, checking responsive designs across viewports, or troubleshooting failed user flows, this skill streamlines the QA process by providing standardized patterns for robust selectors, explicit waits, and incremental testing.
