Selenium With JavaScript

---

Run your JavaScript Selenium tests on the TestMu AI cloud grid across 10,000+ browser/device combinations. The setup is the same for every framework: you connect to the grid and pass your capabilities. This guide covers that shared flow once, then gives you a per-framework quickstart in the tabs below.

Prerequisites

---

Complete these steps before running JavaScript Selenium tests on TestMu AI.

1. Create a TestMu AI account and get your username and access key from the dashboard.
2. Install NodeJS v6 or newer from nodejs.org.
3. Install npm from the official npm website.
4. Download Selenium JavaScript bindings from the official website.

Step 1: Clone the Sample Project

---

Clone the TestMu AI JavaScript Selenium sample repository to your local machine.

git clone https://github.com/LambdaTest/nodejs-selenium-sample
cd nodejs-selenium-sample

Install the required dependencies:

npm install selenium-webdriver

Step 2: Set Your Credentials

---

Set your TestMu AI username and access key as environment variables.

macOS / Linux

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Windows

set LT_USERNAME="undefined"
set LT_ACCESS_KEY="undefined"

Step 3: Configure Your Test Capabilities

---

Update the capabilities object in your test script to define the browser and platform settings.

// index.js
const capabilities = {
        build: 'NodeJS build',      // Name of the build
        name: 'Test 1',             // Name of the test
        platformName: 'Windows 10', // Name of Operating System
        browserName: 'chrome',      // Name of the browser
        browserVersion: 'latest',   // Version of the browser
        resolution: '1280x800',     // Resolution of the screen 
        network: true,              // Enable to capture browser network logs
        visual: true,               // Enable to capture screenshot on every command
        console: true,              // Enable to capture the console log
        video: true                 // Enable to capture the video recording of the test
}

tip

Generate capabilities for your test requirements with the Capabilities Generator.

Step 4: Run the Test

---

Execute the test using one of the following commands.

npm test

Or run the file directly:

node index.js

Step 5: View Your Results

---

After running the test, view your results on the TestMu AI Automation Dashboard.

The dashboard provides:

• Video recordings of each test session
• Screenshots captured at each step
• Console logs from the browser
• Network logs for debugging
• Detailed command logs

Run JavaScript Selenium Tests Using Agent Skills

---

Use AI coding assistants to generate and run JavaScript Selenium tests with the TestMu AI Agent Skill.

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

Install the skill:

git clone https://github.com/LambdaTest/agent-skills.git
cp -r agent-skills/selenium-skill .claude/skills/

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

tip

Install all available framework skills at once by cloning the repository directly into your tool's skills directory (e.g., .claude/skills/, .cursor/skills/).
