Protractor Tutorial

According to StackOverflow’s developer survey, around 30.7% of respondents preferred AngularJS to develop their web applications. These web apps use fewer resources and are faster in comparison to the older static pages.

Finding the right tools for testing can prove to be quite a challenge. But with Angular testing, you need to look no further than the Protractor framework. Protractor is designed by Google developers, by keeping the AngularJS applications in mind.

What is Protractor?

Protractor is a widely used automation testing framework which is used to perform end-to-end testing of Angular web applications. You can utilise the Protractor framework to perform automated browser testing on real browsers by simulating all the browser actions just like a real user would.

Protractor is based on Node.js, a JavaScript framework, and works with it to find web elements in Angular based web applications. Protractor also utilizes Selenium WebDriver, which allows you to automate browser actions. Apart from the Selenium locators, with Protractor you can also access Angular specific locators. In case you’re wondering, ‘what is Selenium’, you can refer to the linked detailed web page on the topic.

Now that you know what Protractor is, and what it does. Let’s further explore why you would use Protractor for Angular testing.

Why Use Protractor For End-to-End Angular Testing?

There are several other reasons for using Protractor for Angular testing, you can find these reasons below in this Protractor testing tutorial:

Angular Specific Locators

Angular applications have certain HTML attributes such as, ng-model, ng repeater etc, which are not a part of Selenium locators. This is why you can not identify these web elements with Selenium. Protractor provides locator strategies specifically for angular web elements, making it the right choice to use it for Angular Testing and allows you to perform angular testing on the without any setup.

End-to-End Testing

Unlike other Selenium test automation frameworks which are only used for unit testing, Protractor can be used to perform End to End testing. You can test the complete flow of a web application right from the beginning to the end.

Flow is checked for the web application in both ‘stage’ as well as in production, to make sure the web applications work as intended when it is integrated with external environments. End-to-End testing helps to ensure that behaviour flow of the web application is as intended, by performing a complete and thorough inspection of the web application from start to finish.

Automatic Waiting

With Protractor you don’t have to worry about adding wait() or sleep() in your Selenium test scripts for Angular testing. In Protractor, the next task in your test scripts automatically starts when the previous task has been completed. This way you don’t have to wait for the page to load.

Support For Selenium Grid

Protractor supports Selenium grid, allowing you to perform parallel testing on multiple browsers instances at the same time. Utilising a grid can save a lot of time spent in running test scripts.

Simple Syntax

With Protractor you can use simple syntax for writing test cases for angular testing. You don’t have to bother with complex code, making it easier for any newbie automation tester to pick it up for automated browser testing.

Support For BDD Frameworks

You also get support for Behaviour-Driven Development testing frameworks with Protractor. With Protractor, you can perform angular testing by utilizing BDD frameworks such as Jasmine and Mocha.
