What is Protractor?

Protractor is an end-to-end test framework for Angular and AngularJS applications. It runs tests against your application running in a real browser, interacting with it as a real user would. It combines powerful tools and technologies such as Selenium, WebDriver, Jasmine, and Mocha to automate browser interactions and verify application behavior from the user's perspective. Protractor is commonly used for regression testing, integration testing, and verifying user flows in web applications.
