Run Your Playwright Tests Using Agent Skills

Instead of manually setting up your Playwright project, you can use Agent Skills to let your AI coding assistant generate production-ready Playwright test automation for you.

The playwright-skill is part of TestMu AI Agent Skills - structured packages that teach AI coding assistants how to write production-grade test automation code.

What Are Agent Skills?

Agent Skills are self-contained packages of instructions, code patterns, debugging guides, and CI/CD configurations for specific testing frameworks. Once installed, your AI assistant works like a Senior QA automation architect with knowledge of:

• Proper project structure for each framework
• Correct dependency versions and configurations
• Both local and TestMu AI cloud execution patterns
• Common pitfalls and debugging approaches
• CI/CD integration with GitHub Actions

Prerequisites

• A TestMu AI account. If you don't have one, sign up for free.
• Your TestMu AI Username and Access Key from the Automation Dashboard.
• An AI coding assistant: Claude Code, GitHub Copilot, Cursor, Gemini CLI, or any compatible tool.

Installing the Playwright Agent Skill

Clone the repository and copy the Playwright skill into your AI tool's skills directory:

git clone https://github.com/LambdaTest/agent-skills.git

# For Claude Code
cp -r agent-skills/playwright-skill .claude/skills/

# For Cursor
cp -r agent-skills/playwright-skill .cursor/skills/

# For GitHub Copilot
cp -r agent-skills/playwright-skill .github/skills/

# For Gemini CLI
cp -r agent-skills/playwright-skill .gemini/skills/

tip

If you prefer installing all available framework skills, clone the repository directly into your tool's skills directory (e.g., .claude/skills/, .cursor/skills/).

Set Up Your Authentication

Configure your TestMu AI credentials as environment variables:

export LT_USERNAME="YOUR_LAMBDATEST_USERNAME"
export LT_ACCESS_KEY="YOUR_LAMBDATEST_ACCESS_KEY"

Running Your First Test Using Agent Skills

Once installed, simply ask your AI assistant to write tests in natural language:

"Write Playwright tests for the login page and run them on TestMu AI cloud using Chrome and Firefox"

"Set up a Playwright TypeScript project with Page Object Model and run tests on TestMu AI"

"Run Playwright tests on real mobile devices on TestMu AI cloud"

The Agent Skill automatically handles:

1. Project setup - Creates the right folder structure, dependencies, and config files
2. Language detection - Maps your request to the correct language (TypeScript, JavaScript, Python, Java, or C#)
3. Execution target - Configures local or TestMu AI cloud execution via CDP WebSocket
4. Best practices - Uses web-first assertions, accessible selectors (getByRole, getByLabel), and Page Object Model
