SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a comprehensive, multi-tier approach to browser automation and visual validation, combining Vibium MCP speed, agent-browser AI comprehension, and Playwright's advanced capabilities to cover simple to complex UI tasks.

Core Features & Use Cases

  • Vibium MCP: fast, script-free interactions for click, type, and screenshot to verify UI changes.
  • agent-browser: AI-driven page understanding, persistent sessions, and semantic element selection for robust exploration.
  • Playwright: handling complex logic, data-driven tests, network mocking, file uploads, and multi-context scenarios.
  • Visual regression: screenshot-based comparisons to detect unintended UI changes across devices and builds.
  • Use cases include quick visual verifications of UI changes, form testing, multi-page flows, and cross-device layouts.

Quick Start

Start with Vibium MCP to verify a UI change, then escalate to agent-browser for structure understanding or Playwright for advanced automation as needed.

Frequently Asked Questions about browser-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate visual regression testing to detect unintended UI changes?

Automate visual regression testing by capturing screenshots with Vibium MCP or Playwright, then comparing visual diffs across builds and devices to detect unintended UI changes. This Skill unifies those tools to streamline screenshot comparisons and validate layouts.

What is the best way to handle complex browser automation logic like network mocking or file uploads?

The best way to handle complex browser automation logic like network mocking or file uploads is using Playwright. This Skill escalates from simple Vibium MCP interactions to Playwright for advanced data-driven tests, multi-context scenarios, and end-to-end UI testing.

Can I use AI to understand page structure during automated UI testing?

Yes, you can use AI to understand page structure during automated UI testing via agent-browser. It provides AI-driven page comprehension, persistent sessions, and semantic element selection for robust exploration when simple script-free interactions are insufficient.

How do I verify UI changes quickly without writing test scripts?

Verify UI changes quickly without test scripts using Vibium MCP for fast, script-free interactions like click, type, and screenshot. This Skill enforces a vibium-first approach to rapidly validate simple UI modifications before escalating to heavier automation tools.

Does this approach support cross-device responsive checks and multi-page form testing?

Yes, this approach supports cross-device responsive checks and multi-page form testing. By combining Vibium MCP for quick checks and Playwright for complex flows, it covers end-to-end UI testing across different device layouts and automated form submissions.
