Learn how to use Node.js environment to configure and run your JavaScript automation testing scripts on the LambdaTest Selenium cloud platform.
- Pre-requisites
- Run Your First Test
- Executing The Test
- Testing Locally Hosted or Privately Hosted Projects
Before getting started with Selenium automation testing on LambdaTest, you need to:
- Download and install NodeJS. You should be having NodeJS v6 or newer. Click here to download.
- Make sure you are using the latest version of JavaScript.
- Install npm from the official website by clicking here.
- Download Selenium JavaScript bindings from the official website. Latest versions of Selenium Client and WebDriver are ideal for running your JavaScript automation testing script on LambdaTest’s Selenium Grid.
Clone the LambdaTest’s nodejs-selenium-sample repository and navigate to the code directory as shown below:
git clone https://github.com/LambdaTest/nodejs-selenium-sample
cd nodejs-selenium-sample
You need to install the following dependencies to your package.json
file:
You will need to install the selenium webdriver
to make the connection to the GRID
:
npm install selenium-webdriver
Create a new file as index.js
in your current project or the sample folder and add the below code snippet which will call the installed driver.
// index.js
const webdriver = require('selenium-webdriver');
Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest Selenium Grid. You can obtain these credentials from the LambdaTest Automation Dashboard or through LambdaTest Profile.
Set LambdaTest Username
and Access Key
in environment variables.
- 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"
Now you can add the GRID HOST
which is used to connect your current test suites to be executed on the cloud grid.
// index.js
const GRID_HOST = 'hub.lambdatest.com/wd/hub';
const gridUrl = 'https://' + USERNAME + ':' + KEY + '@' + GRID_HOST;
const driver = new webdriver.Builder().usingServer(gridUrl).withCapabilities(capabilities).build();
The above grid connect will create the Webdriver
for the test suite to execute the Selenium
commands for your test.
In the test script, you need to update your test capabilities. In this code, we are passing browser, browser version, and operating system information, along with LambdaTest Selenium grid capabilities via capabilities object. The capabilities object in the above code are defined as:
// index.js
const capabilities = {
build: 'NodeJS build', // Name of the build
name: 'Test 1', // Name of the test
platform: 'windows 10', // Name of Operating System
browserName: 'chrome', // Name of the browser
version: '67.0', // 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
}
Note: You can generate capabilities for your test requirements with the help of our inbuilt Capabilities Generator tool.
Now you write your selenium test cases in your index.js
file:
function searchTextOnGoogle() {
// 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();
});
}
searchTextOnGoogle();
Please execute the following command below to run your tests:
npm test OR node index.js
Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard. LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.
You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid cloud using LambdaTest Tunnel app. All you would have to do is set up an SSH tunnel using LambdaTest Tunnel app and pass toggle tunnel = True
via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are made live.
Refer our LambdaTest Tunnel documentation for more information.
Here’s how you can establish LambdaTest Tunnel.
Download the binary file of:
Open command prompt and navigate to the binary folder.
Run the following command:
LT -user {user’s login email} -key {user’s access key}
So if your user name is lambdatest@example.com and key is 123456, the command would be:
LT -user lambdatest@example.com -key 123456
Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on tunnel capabilities in the code shown below :
Tunnel Capability
const capabilities = {
tunnel: true,
}
