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.

What Is Protractor?

Protractor is a JavaScript framework, end-to-end test automation framework for Angular and AngularJS applications.

What Makes Protractor & Selenium A Good Fit For Your Automation Test Scripts?

Protractor Selenium provides new locator methods that actually make it easier to find elements in the DOM.

Writing Sample Code for Automation Testing With Protractor and Selenium

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.

Executing Cross Browser Parallel testing, Protractor Selenium & LambdaTest (Cloud)

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.

Cross Browser Testing With Protractor & Selenium

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.

Using Selenium Locators In Protractor

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.

Debugging Protractor Tests

To make sure that your Selenium automation tests function as intended, debugging can be an effective option. Check the blog to know more.

List of Selenium Locators in Protractor

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.
