SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables automated iterative UI testing using the Playwright MCP server, reducing manual screenshot work and accelerating visual verification of web apps.

Core Features & Use Cases

  • Automated browser navigation, interaction, and state verification against a running application.
  • Programmatic screenshot capture and visual checks to detect UI regressions.
  • Iterative development workflow that quickly converges on a stable UI by re-running steps after fixes.
  • Use Case: Validate the main user flows across pages by looping through navigate, click, fill, and screenshot steps with deterministic results.

Quick Start

Configure the MCP server and ensure your dev server is running, then run the following pattern:

  • Start your app (e.g., bun dev) to serve the UI locally.
  • Confirm MCP server configuration in workspace settings.
  • playwright_navigate → http://localhost:5173
  • playwright_screenshot → "initial-state"
  • Analyze: identify any UI issues, then update interactions or selectors
  • Repeat from the navigate step to iterate until the UI is stable.

FAQPage Schema
How do I automate UI testing with Playwright?

Automate UI testing with Playwright by using the MCP server to programmatically navigate pages, capture screenshots, click elements, and verify visual states. This approach reduces manual testing work and accelerates detection of UI regressions across your application.

Can I use Playwright for browser automation and visual verification?

Yes, Playwright supports browser automation and visual verification through the MCP server. You can navigate to URLs, interact with page elements, take screenshots, and evaluate JavaScript to verify UI states deterministically during development.

What's the best way to set up iterative UI testing during development?

Run your dev server locally, configure the Playwright MCP server, then iterate by navigating to your app, capturing screenshots, analyzing UI issues, updating selectors or interactions, and re-running steps until the UI stabilizes. This workflow converges quickly on stable builds.

Do I need a local dev server to run Playwright UI tests?

Yes, Playwright MCP testing requires both a running Playwright MCP server and a local dev server (like one running on localhost:5173) to automate browser navigation and interaction against your application.

How can I detect UI regressions with automated screenshot capture?

Capture programmatic screenshots at each step of your user flow, then analyze them for visual changes or UI inconsistencies. Automate this process with Playwright MCP commands to repeatedly verify UI states and catch regressions early in development.

What commands does Playwright MCP provide for UI testing?

Playwright MCP provides commands including playwright_navigate (move to URLs), playwright_screenshot (capture visuals), playwright_click (interact with elements), and playwright_evaluate (run JavaScript) to drive deterministic, repeatable UI checks.
