What is protractor used?
The Protractor framework is used to run automation tests that interact with the WebElements in the DOM. This open-source test automation framework is written in NodeJS.
It is used for E2E (end-to-end) testing of Angular and non-Angular applications. You can also use Selenium locators in Protractor and perform operations like mouse clicks, button clicks, filling up forms, and more.
There are a number of Selenium Protractor tutorials that can help you get started with Protractor for web automation testing. To summarize, you can choose Protractor as the de facto test automation framework to perform E2E testing of Angular and non-Angular applications.
