Sample NodeJS Automation Scripts For LambdaTest Selenium Grid

NodeJS Test Tutorial

Node.js is an efficient, light weight and cross platform runtime environment for executing JavaScript code. npm(node package manager) is the largest ecosystem of open source libraries. LambdaTest enables node.js scripts to run on the Selenium automation grid. This tutorial will help you run Nodejs automation scripts over LambdaTest Selenium Grid.

Prerequisites for Node.js Tutorial

1. Install npm.

sudo apt install npm

2. Install NodeJS.

sudo apt install nodejs

Steps to Run your First Test

Step 1. Clone the NodeJs Selenium Repository.

git clone https://github.com/4msha/nodejs-selenium-sample.git

Step 2. Export the Lambda-test Credentials. You can get these from your automation dashboard.

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"

Step 3. Inside nodejs.selenium repository install necessary packages.

cd nodejs-selenium-sample
npm i

Step 4. To run your First Test.

npm test
or node index.js

See the Results

You can check your test results on the Automation Dashboard.

Understanding the Test.

1. Importing Selenium Wedriver,setting up username, access-key, and grid-host.

const webdriver = require('selenium-webdriver');

// USERNAME & KEY can be found at automation dashboard
const USERNAME = 'shwetas';
const KEY = 'xhfQswR5454';

// gridUrl: gridUrl can be found at automation dashboard
const GRID_HOST = 'hub.lambdatest.com/wd/hub';

2. Define the Test function and capabilities.

function searchTextOnGoogle() {

    // Setup Input capabilities
    const capabilities = {
        platform: 'windows 10',
        browserName: 'firefox',
        version: 'latest',
        resolution: '1280x800',
        geoLocation :'IT',
        network: false,
        visual: false,
        console: false,
        video: true,
        name: 'Test 1', // name of the test
        build: 'NodeJS build' // name of the build
    }

    // URL: https://{username}:{accessToken}@beta-hub.lambdatest.com/wd/hub
}
searchTextOnGoogle()

3. Next, we create the grid url and create the selenium driver object.

    const gridUrl = 'https://' + USERNAME + ':' + KEY + '@' + GRID_HOST;

    // setup and build selenium driver object
    const driver = new webdriver.Builder()
        .usingServer(gridUrl)
        .withCapabilities(capabilities)
        .build();

4. At last, we try to search LambdaTest on google.

 // navigate to a url, search for a text and get title of page
    driver.get('https://www.google.com/ncr').then(function() {
        driver.findElement(webdriver.By.name('q')).sendKeys('LambdaTest\n').then(function() {
            driver.getTitle().then(function(title) {
                setTimeout(function() {
                    console.log(title);
                    driver.executeScript('lambda-status=passed');
                    driver.quit();
                }, 5000);
            });
        });
    }).catch(function(err){
        console.log("test failed with reason "+err)
        driver.executeScript('lambda-status=failed');
        driver.quit();
    });
