TestMu AI Skills - Production-Grade Agent Skills for Test Automation

Battle-tested Agent Skills for Claude Code, Copilot, Cursor, Gemini CLI & more - covering every major test automation framework across 15+ languages.

---

What Is This?

TestMu AI Skills is a curated collection of Agent Skills that teach AI coding assistants how to write production-grade test automation. Each skill is a self-contained package of instructions, code patterns, debugging guides, and CI/CD configurations for a specific testing framework.

Instead of getting generic test code, your AI agent becomes a Senior QA automation architect that knows:

• The right project structure for each framework
• Correct dependency versions and configurations
• Both local and cloud (TestMu AI) execution patterns
• Common pitfalls and how to debug them
• CI/CD integration with GitHub Actions
• Best practices that ship in real-world codebases

Quick Start

Option 1: Install a Single Skill

# Clone the repo and copy the skill you need
git clone https://github.com/LambdaTest/agent-skills.git
cp -r agent-skills/selenium-automation-skill .claude/skills/

# Or for Cursor / Copilot
cp -r agent-skills/playwright-automation-skill .cursor/skills/

Option 2: Install All Skills

# Claude Code
git clone https://github.com/LambdaTest/agent-skills.git .claude/skills/agent-skills

# Gemini CLI
git clone https://github.com/LambdaTest/agent-skills.git .gemini/skills/agent-skills

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

# Universal (.agent/ works with most tools)
git clone https://github.com/LambdaTest/agent-skills.git .agent/skills/agent-skills

Then just ask your AI assistant naturally:

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

"Set up Cypress component tests for the React dashboard and upload screenshots on failure"

"Create JUnit 5 tests for the payments service with Mockito and GitHub Actions CI"

"Run Playwright tests locally against http://localhost:3000 with trace and video enabled"

Skill Architecture

Each skill follows the Agent Skills Standard with progressive disclosure:

selenium-automation-skill/
├── SKILL.md                          # Core instructions (<500 lines)
│   └── Workflow + decision trees     # When/how to use the skill
└── reference/
    ├── playbook.md                   # Complete implementation guide
    │   ├── Project setup & dependencies
    │   ├── Code patterns & page objects
    │   ├── Cloud integration (LambdaTest)
    │   ├── CI/CD configuration
    │   ├── Debugging table (12+ common problems)
    │   └── Best practices checklist (14+ items)
    ├── advanced-patterns.md          # Advanced topics
    └── cloud-integration.md          # Cloud-specific patterns

How it works:

1. Metadata (name + description) is always loaded — ~100 tokens per skill
2. SKILL.md body loads when triggered — core workflow and patterns
3. Reference files load on-demand — detailed code, debugging, CI/CD

Cloud Testing with TestMu AI

Skills that support browser/device testing include TestMu AI cloud integration out of the box.

Get Your TestMu AI Credentials

Make sure you have your TestMu AI credentials with you to run test automation scripts on TestMu AI Selenium Grid. You can obtain these credentials from the TestMu AI Automation Dashboard or through TestMu AI Profile.

Set TestMu AI USERNAME and ACCESS_KEY in environment variables.

• Copy .env.example to .env and fill in your credentials.

or add credentials directly from your terminal:

For Linux/macOS:

export LT_USERNAME="YOUR_USERNAME"
export LT_ACCESS_KEY="YOUR_ACCESS_KEY"

For Windows:

set LT_USERNAME="YOUR_USERNAME"
set LT_ACCESS_KEY="YOUR_ACCESS_KEY"

Run Tests on the Cloud

Then ask your AI assistant naturally:

"Run my Selenium tests on Chrome, Firefox, and Safari on TestMu AI with OS versions Windows 11, macOS Sonoma, and Ubuntu 22.04"

"Execute Playwright tests across 5 browsers in parallel on TestMu AI, tag the build as 'release-1.8.2', and capture traces on failure"

"Set up Cypress on TestMu AI with video recording and JUnit reports, and upload artifacts to the dashboard"

"Test my localhost app through the TestMu AI tunnel (http://localhost:3000) using Playwright and validate login + checkout flows"

"Run mobile web tests on real devices via TestMu AI tunnel and verify the responsive layout on iPhone 15 and Pixel 8"

View your test results, logs, and video recordings on the TestMu AI Automation Dashboard.
