Protractor is a comprehensive testing framework designed specifically for Angular applications, utilizing WebDriverJS as its foundation.
As someone who is just beginning to explore web testing, I am curious about the benefits of choosing Protractor over using WebDriverJS alone. What unique advantages does Protractor offer in comparison?
One of the key benefits of using Protractor is its deep integration with Angular. This unique feature offers several advantages, such as:
Protractor offers a range of valuable features that are centered around Edwin's ideas, as mentioned here. Protractor recognizes the Angular nature of the app being tested, enabling it to interact with specific services and monitor them effectively.
Unlike traditional end-to-end tests using WebDriverJS or similar frameworks, which often involve unnecessary waits/sleeps, Protractor streamlines the process by automatically handling sleep periods during pending Ajax requests. This eliminates the need for manual guesswork regarding request duration and prevents test failures due to delays.
In addition, Protractor simplifies element detection based on factors such as the input's ng-model, {{bindings}} on the page, or ng-repeat elements. This enhances the efficiency of locating desired elements for testing purposes.
Julie's decision to develop Protractor over relying solely on WebDriver is explained in depth in this video, where she addresses this question during the Q&A session despite potential challenges related to video quality.
When building an application with AngularJS, leveraging Protractor for testing purposes can prove to be advantageous.
The reasons behind this are manifold:
Protractor serves as an end-to-end testing framework specifically designed for AngularJS applications, seamlessly integrating various robust tools and technologies like Node.js, Selenium, webDriver, Jasmine, Cucumber, and Mocha.
It offers a range of customization options derived from Selenium, streamlining the process of creating tests for AngularJS applications.
Protractor enhances testing efficiency by minimizing the need for excessive "sleeps" and "waits" within your tests, thus optimizing sleep and wait durations.
By aligning test organization with Jasmine, Protractor enables the creation of both unit and functional tests using the same framework.
Capable of running tests on actual browsers as well as headless browsers.
Enables test execution targeting remote addresses.
Furthermore, AngularJS provides its own locators such as model, repeater, and binding, which can be effortlessly interpreted by Protractor for object identification.
Protractor represents a significant advancement from Selenium Webdriver tailored specifically for JavaScript applications.
While it's not exclusively designed for AngularJS apps, they are commonly associated due to their compatibility. However, some adjustments may be necessary to use it effectively on non-angular pages.
If transitioning your site/application to Angular is part of your future plans, initiating Protractor E2E testing now can set you on the right path.
