AngularJS with Selenium: Tutorial to Run Your First Test on LambdaTest


In this topic, you will learn how to perform AngularJS Automated Testing using LambdaTest Selenium cloud platform.

Objective‚Äč


By the end of this topic, you will be able to:

  1. Perform AngularJS automated testing on Lambdatest Selenium grid with Karma test runner.
  2. Leverage LambdaTest’s Advanced capabilities for AngularJS test automation.
  3. Test your locally hosted pages using AngularJS test automation.
  4. Run your test cases in parallel using AngularJS test automation to reduce build times.

Prerequisites For Running Karma With Our Online Selenium Grid‚Äč


Before getting started with automated scripts using AngularJS Automated Testing using Cloud Selenium Grid, you need to:

  • Download and install NodeJS and node package manager or npm. Make sure you have NodeJS v6 or newer. Click here to download.
$ brew install node

Sample Test Case‚Äč


All the code samples in this documentation can be found in the AngularJS LambdaTest Repository on GitHub. You can either download or clone the repository to quickly run your tests.

Installing Dependencies‚Äč

You need to install the following dependencies:

Step 1: Install npm from the official website by clicking here. Here is the code you can run in your terminal to upgrade npm.

npm install [email protected] -g

Step 2: Next, you need to install Angular CLI. Run the below command to install:

$ npm install -g @angular/cli

Setting up Your Authentication‚Äč

Step 3: Set LambdaTest username and access key in environment variables. It can be obtained from LambdaTest 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"

Setting up the Test Environment‚Äč

Step 4: Clone the LambdaTest’s angular-karma-sample repository and navigate to the code directory as shown below:

git clone https://github.com/LambdaTest/angular-karma-sample
cd angular-karma-sample

Step 5: Install the project dependencies using the below command:

$ npm install

Setting up the Test Config‚Äč

Step 6: If you look at karma.conf.js file you will find that 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 is defined as:

customLaunchers: {
chrome: {
base: 'WebDriver',
config: webdriverConfig,
browserName: 'chrome',
platform: 'windows 10',
version: '71.0',
name: 'Karma With Heartbeat',
tunnel: true, // In case karma is running on local machine
video: true, // capture video for your test
user: process.env.LT_USERNAME,
accessKey: process.env.LT_ACCESS_KEY,
pseudoActivityInterval: 15000 // 15000 ms heartbeat to avoid timeouts
}
}

You can generate capabilities for your test requirements with the help of our inbuilt Capabilities Generator tool.

Writing your Test Cases‚Äč

The example mentioned below would help you to execute your AngularJS automation testing on Google Chrome.

import { AppPage } from './app.po';
import { browser, logging } from 'protractor';

describe('workspace-project App', () => {
let page: AppPage;

beforeEach(() => {
page = new AppPage();
});

it('should display welcome message', () => {
page.navigateTo();
expect(page.getTitleText()).toEqual('Welcome to karma-sample!');
});

afterEach(async () => {
// Assert that there are no errors emitted from the browser
const logs = await browser.manage().logs().get(logging.Type.BROWSER);
expect(logs).not.toContain(jasmine.objectContaining({
level: logging.Level.SEVERE,
} as logging.Entry));
});
});

Run Your First Test‚Äč


Navigate to the directory where you cloned the sample of Karma-Angular and run the following command.

karma start karma.conf.js

or you could also run the test using:

npm test

Testing Locally Hosted or Privatley Hosted Projects‚Äč

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 [email protected] and key is 123456, the command would be:

LT -user [email protected] -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

tunnel: true,

Running Your Parallel Tests Using AngularJS‚Äč


Executing Parallel Tests Using AngularJS‚Äč

To run parallel tests using AngularJS, we would have to execute the below commands in the terminal:

  • For the above example code:
ng test
