Your avatar

Protractor is an end-to-end testing framework for Angular JS and Angular apps that is open-source. It was created on top of Web Driver by Google.

Protractor may be used to replace the existing "Angular Scenario Runner" Angular JS E2E testing framework. It also serves as a solution integrator, bringing together strong technologies like Web Driver, Selenium, Mocha, Node JS, Cucumber, and others.

About Protractor

For Angular and Angular JS apps, Protractor is a well-known open-source end-to-end testing framework. It also produces automated regression tests for conventional web apps in addition to testing Angular JS apps. It allows us to test our application as if it were a very useful one because the test displays in an original browser.

Working of Protractor

The testing framework Protractor, in conjunction with Selenium, offers automated test support for influencing a user's collaboration with an Angular JS application running in a browser or on a mobile device.

Protractor's operation may be described by following the steps below:

Step1: The first step is to write the tests. It's possible to do it using jasmine, cucumber, or mocha.

Step 2: Now we must do the test, which may be done with the assistance of a protractor. It's known as a test runner.

Step 3: The browser will be controlled by the Selenium server.

Step 4: The Selenium Web Driver is used to request the Browser APIs.

Benefits of Protractor

The following are some of the benefits of this open-source end-to-end framework:

It has the fastest trial speed

Provides auto-synchronization features

Allows for equitable testing across several browsers

Provides all of the benefits of the Selenium Web Driver

To develop the test, work well with Jasmine's framework

Protractor is an open-source tool that is relatively easy to set up and use

Drawbacks of Protractor

The following are the drawbacks of this open-source end-to-end testing framework.

Because it is a UI-driven measurement tool, it only offers a front-end trial.

Because it is only accessible for JavaScript, the user must be familiar with the language.

Because it is a cover for Web Driver JS, it does not reveal any verticals in browser automation.


If Google has gone to such lengths to make Protractor operate flawlessly, we should make the most of it. It will make your life considerably simpler, at least for AngularJS websites. You can get a training course for learning more about Protractor such as Protractor Online Training. The training will enhance your skills and will help you in establishing a fine career.
