According to StackOverflow’s developer survey, around 30.7% of respondents preferred AngularJS to develop their web applications. These web apps use fewer resources and are faster in comparison to the older static pages.
The majority of the web products use AJAX (Asynchronous JavaScript and XML), due to which elements on the page are loaded at varying time intervals. This can lead to timing issues when automation testing is performed using the Selenium framework. What if a test is run on a WebElement that is not present in the DOM? The findElement function will raise ElementNotVisibleException.
There are a lot of tools in the market who uses Selenium as a base and create a wrapper on top of it for more customization, better readability of code and less maintenance for eg., Watir, Protractor etc., To know more details about Watir please refer Cross Browser Automation Testing using Watir and Protractor please refer Automated Cross Browser Testing with Protractor & Selenium.

Selenium Protractor Tutorial
Protractor is developed by Google Developers to test Angular and AngularJS code. Today, it is used to test non-Angular applications as well. It performs a real-world user-like test against your application in a real browser. It comes under an end-to-end testing framework. As of now, Selenium Protractor has proved to be a popular framework for end-to-end automation for AngularJS.
Let’s talk about what it does:
- Protractor, built on WebDriver JS (Selenium), offers Angular-specific locator strategies.
- It helps to construct automated tests for applications other than Angular JS and is not just intended to test AngularJS applications.
- Page object design pattern is supported by Protractor Selenium, which improves in producing clear and legible code. Automation testers need to write clean code.
- Frameworks like Jasmine, Cucumber, and others are fully integrated with Protractor.

Protractor is a JavaScript framework, end-to-end test automation framework for Angular and AngularJS applications.
Protractor Selenium provides new locator methods that actually make it easier to find elements in the DOM.
Two files are required to execute Protractor Selenium tests for end-to-end automation: Specs & Config. Go through the link above to understand in a better way.
To carry out extensive, automated cross browser testing, you can't imagine installing thousands of the available browsers on your own workstation. The only way to increase browser usage is through remote execution on the cloud. To execute your automation test scripts across a variety of platforms and browser versions, LambdaTest offers more than 3000 browsers.
We recommend Selenium for end-to-end automation for AngularJS because both are maintained and owned by Google, and they build JavaScript test automation framework to handle AngularJS components in a way that better matches how developers use it.
For scripting, selenium locators are essential since if they're off, your automation scripts won't run. Therefore, in any testing framework, these Selenium locators are the foundation of your Selenium test automation efforts.
To make sure that your Selenium automation tests function as intended, debugging can be an effective option. Check the blog to know more.
Get familiar with global variables that are majorly used in locating the DOM elements with examples for better understanding of these Selenium locators in protractor.
If you are not familiar with writing Selenium test automation on Protractor, here is a blog for you to get you understand in depth.
Selenium tests are asynchronous and there are various reasons for a timeout to occur in a Protractor test. Find out how to handle timeouts in this Protractor tutorial.
In this Protractor tutorial, learn how to handle frames or iframes in Selenium with Protractor for automated browser testing.
Handle alerts and popups in Protractor more efficiently. It can be confusing. Here's a simple guide to understand how to handle alerts and popups in Selenium.

Hey Devan Skeem,
For Mocha-Chai & Jasmine-Chai, you can pass the below commands on your script:
let username = process.env.LT_USERNAME,
accessKey = process.env.LT_ACCESS_KEY,
For Protractor-Jasmine:
exports.config = {
lambdatestUser: process.env.LT_USERNAME,
lambdatestKey: process.env.LT_ACCESS_KEY,
}
To learn more on how to get the LambdaTest Username and Access Key, first create your LambdaTest Account > Account Setting > Password and Security tab, and you can find the credentials and use them in your script. Follow our LambdaTest support documentation for complete guidance.
