Protractor is an end-to-end testing framework specifically designed for Angular applications. It allows you to automate the testing of your Angular application's user interface, including interactions, navigation, and form submissions. Protractor uses the Selenium WebDriver to simulate user actions and verify the expected behavior of your application.
One of the key features of Protractor is its ability to handle asynchronous behavior in Angular applications. It automatically waits for Angular to stabilize before executing test steps, ensuring that your tests are reliable and accurate. Protractor also provides built-in support for Angular-specific elements and features, making it easier to write tests for Angular applications.
Compared to other testing frameworks like Selenium or Cypress, Protractor is specifically tailored for Angular applications and provides seamless integration with Angular's testing ecosystem. It is actively maintained and widely used in the Angular community.
