2. Playwright MCP Server

A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.

2.1 Direct Interaction

The Playwright MCP Server can control your web browser in real time. Instead of just writing code for you, it executes browser actions directly.

Playwright provides high-level methods that interact with the page as a real user would, including built-in auto-waiting mechanisms to ensure elements are ready before acting.

2.2 Generate automation scripts

The Playwright MCP Server can automatically generate test scripts based on your requirements. Simply describe what you want to test, and it will create the necessary Playwright code with proper selectors and assertions.

With Playwright MCP, it will launch the browser and execute the steps we share.

2.3 Fix broken test

When tests fail due to UI changes or timing issues, the MCP Server can analyze the failures and suggest fixes. It can update selectors, add proper waits, and handle dynamic content automatically.

It is the core feature of Self-Healing in Automation Testing in the context of Generative Automation Testing utilizing Playwright and the Model Context Protocol (MCP).

2.4 Test execution

Execute your Playwright tests directly through the MCP Server with real-time feedback and detailed reporting. The server handles browser initialization, test execution, and cleanup automatically.

        ]
      }
    }
}

3.3 Verify Installation

To verify that Playwright MCP Server is working correctly:

1. Open a new file in VS Code
2. Start GitHub Copilot Chat (Ctrl+I or Cmd+I)
3. Type: "@playwright navigate to https://google.com and take a screenshot"
4. Copilot should generate Playwright code using MCP Server capabilities

3.4 Start Playing with Playwright MCP Server

Now you're ready to start using Playwright MCP Server with GitHub Copilot! Here are some examples:

• Generate test scripts: "@playwright create a test to login with username and password"
• Fix broken tests: "@playwright update selectors in my failing test"
• Execute tests: "@playwright run all tests and show me the results"
• Debug issues: "@playwright analyze why my test is failing"

The AI will generate accurate Playwright code with proper selectors, waits, and best practices automatically!

4. Conclusion
