Does it support testing for mobile responsiveness?

Absolutely. You can evaluate viewport dimensions via JS evaluation and check the visibility of mobile-specific elements like hamburger menus or hidden sidebars.

What browser engine does this skill use?

It utilizes the OpenBrowser-AI framework which interacts directly via the Chrome DevTools Protocol (CDP) for high-fidelity automation and LangGraph orchestration.

How are assertions handled in this skill?

It uses standard Python assert statements within the execute_code environment, providing clear feedback and error messages if a test condition fails.

Can I test complex multi-step forms?

Yes, the skill supports sequential input, click actions, and state verification to handle even the most intricate multi-page user journeys.

Can I run these tests against a local development server?

Yes, as long as the environment running Claude Code has network access to your local or staging URL, it can navigate to and interact with those pages.

Security & Testing

Automates web application testing by simulating realistic user journeys and verifying browser behavior through asynchronous Python execution.

The e2e-testing skill empowers developers to perform comprehensive quality assurance by automating complex browser interactions directly within the Claude Code environment. By leveraging a persistent namespace and asynchronous browser functions, it enables the simulation of full user lifecycles—from initial landing and form submission to multi-page navigation and responsive layout verification. This skill is essential for validating deployments, testing regression scenarios, and ensuring that critical user paths remain functional across application updates without manual intervention, providing clear feedback through standard Python assertions.

Key Features

01Automated user flow simulation including form inputs, clicks, and multi-page navigation.

02Responsive design auditing by checking viewport dimensions and CSS-driven element visibility.

03Comprehensive error handling verification by capturing validation messages and UI states.

04Real-time DOM state assertions and content verification using JavaScript evaluation.
