What Is Protractor?
Built on WebDriverJS, Protractor is a commonly used end-to-end testing framework designed to automate Angular and AngularJS applications. Protractor extends the capabilities of WebDriverJS by offering a simplified API tailored for testing Angular applications. This API enables testers to write tests in JavaScript, leveraging the power of WebDriverJS while providing additional support for Angular-specific features.
Protractor’s native support for Angular sets it apart from Selenium. It understands Angular-specific behavior, such as two-way data binding, dynamic element updates, and asynchronous tasks. This specialized support allows testers to write tests that align closely with how Angular applications work.
Protractor With Selenium
Protractor is built on top of WebDriverJS, which is the JavaScript implementation of Selenium WebDriver. This means that Protractor utilizes the underlying capabilities of Selenium WebDriver to interact with web browsers. By combining Protractor and Selenium, you can leverage the specialized Angular support of Protractor while also benefiting from the extensive language support, community, and browser compatibility of Selenium.
This integration allows you to utilize the strengths of both frameworks. Protractor’s specialized support for Angular ensures efficient testing of Angular applications, while Selenium provides the versatility and broad language support required for testing a wide range of web applications.

Protractor Vs. Selenium: Which Is Best for You?
Choosing between Protractor and Selenium depends on various factors based on your specific requirements, project context, and team preferences. Given below are some of the important factors to consider when making your decision:
Application Technology Stack: If your project involves Angular or AngularJS applications, Protractor’s specialized support for Angular-specific behavior makes it a strong contender. It provides a more efficient and seamless testing experience for Angular applications. However, if your project involves non-Angular web applications, Selenium’s versatility becomes a key advantage.
Language Preferences: Consider the programming languages your team is proficient in or prefers to work with. Protractor primarily focuses on JavaScript, which may be beneficial if your team has a strong JavaScript background. Selenium offers support for multiple languages, allowing you to leverage existing skills or choose a language that aligns with your preferences.
Testing Framework Integration: If your team is already utilizing a specific testing framework like Jasmine or Mocha, Protractor’s built-in integration with these frameworks can simplify your test code and improve maintainability. Selenium’s compatibility with various testing frameworks provides flexibility in choosing the most suitable framework for your needs.
Browser Compatibility: Consider the extent of browser coverage required for your testing. If your project demands testing on a wide range of browsers, Selenium’s broader compatibility with additional browser drivers may be advantageous.
Community Support and Documentation: Evaluate the level of community support and availability of documentation you require for your project. Selenium’s larger community ensures extensive resources, online forums, and community-driven solutions. Protractor, although with a smaller community, still has an active user base that provides assistance and support.
Performance and Speed: Assess whether your application heavily relies on Angular-specific behavior and features. If so, Protractor’s specialized support and automatic waiting for Angular tasks may offer better performance. However, if your testing requirements extend beyond Angular applications, Selenium’s optimization and wide adoption ensure good performance for general web testing scenarios.
By carefully evaluating these factors and understanding the features of both Protractor and Selenium, you can make an informed decision that aligns with your test automation needs and project goals.
Summing It Up!
In conclusion, Protractor and Selenium are both powerful test automation frameworks with their own strengths and use cases. Protractor is specifically tailored for Angular and AngularJS applications, providing specialized support and seamless integration with JavaScript testing frameworks. It offers a simplified API, automatic waiting for Angular tasks and native support for Angular-specific features.
