Hire Protractor Javascript specialist For Any Job

WanTo Hire a Freelance Protractor Javascript Specialist

It was first created by Google Developers as a framework for angular applications and was later made available as open source. Protractor now supports applications that are both Angular and Non-Angular. The protractor is a wrapper built on top of Webdriver.js; it supports all Selenium Webdriver-supported functionalities in addition to those unique to Angular.

The official javascript implementation of Selenium is WebDriverJs. Similar to selenium java, it communicates with the browser using the Selenium JSON-Wire-Protocol. In order to communicate with the browser, Protractor relies on WebdriverJs.

As is common knowledge, practically all applications are created using JavaScript. When JavaScript grows in size and becomes complex for applications as a result of the growing number of applications themselves, the role of testers becomes challenging. When using JUnit or Selenium WebDriver to test AngularJS apps, which use expanded HTML syntax to represent web application components, it can be very challenging to capture the web elements. As a result, by post your project needs to Paperub.com, you can engage a freelancer for any such requirements if you need a professional Protractor Javascript specialist. Hire a Protractor JavaScript specialist freelancers in India, Canada, the UK, the UK, Turkey, and Australia from Paperub.com is very easy.

How does it work?

An end-to-end testing framework called Protractor is built on WebdriverJS, which is a set of javascript bindings for the Selenium webdriver API. That indicates that the WebdriverJS API offers JavaScript APIs for tests. Protractor is a Selenium-based test framework, which implies that to simulate user activities, it communicates with the Selenium server and WebDrivers like ChromeDriver, GeckoDriver, SafariDriver, etc.

When the commands from your test scripts are sent to the Selenium server, which then interacts with the browser driver and carries them out (performs actions). The assertion framework is the following; Protractor supports a number of assertion frameworks, including Jasmine, Mocha, etc. This assertion framework enables us to validate or check the values, and as a result, determines if your test is successful or unsuccessful. For writing and running our end-to-end tests, we use Protractor, WebdriverJS, Selenium Server, Browser Driver, and Assertion Framework. Working criteria and its technicalities will not be clear to you until or unless you are skilled enough in Java at the same time Protractor JavaScript is more than this, therefore you may need a an expert for assistance. A Protractor JavaScript specialist knows technicalities much better, and can help in your project too.

Features of protractor

Supports Angular-specific locators: Protractor offers expanded support for the locators ng-model, ng-bind, ng-repeat, and other angular-specific locators that are included with the angular application. Protractor already has angular locators prepared for you, so you can use them by model, by the repeater, etc. without having to generate complicated XPath.

Supports both Non-Angular and Angular applications: Protractor offers enhanced support for Angular, but it also offers support for applications that don't use Angular. That implies you can still use the Protractor framework and perform complete end-to-end automation test automation even if your application has parts that are angular and parts that are not.

Supports Cross-Browser testing: Our scripts can be executed in a variety of browsers, including Chrome, Firefox, Safari, IE11, and Edge. Cross-browser testing configuration is simple and quick to complete. In our forthcoming tutorials, we will go over this subject in great detail.

Supports Parallel Execution: Suppose we have a large number of test cases. It would take a long time to run each test case sequentially, or one after the other. Here, parallel processing is helpful. In a run in two instances of the browser, each executes two-two test cases at a single moment in time, therefore more test cases will be executed in less time if you use parallel execution, for example, if you have four test cases.

Supports Headless Browser: A headless browser is one that lacks a UI. The headless browser is also supported by Protractor.

Supports Extensibility: Protractor may use the extensive selection of packages offered by the node.js framework because it is a node.js application. Therefore, installing node packages allows one to expand their framework or add new functionality. For instance, Jasmine HTML Reporter can be used to generate HTML reports, and eslint or tslint can be installed to produce clean code. The same applies to installing your preferred node packages.

Supports Reporting plugins: It's simple to configure the report in Protractor compared to other open source automation frameworks that aren't based on Node.js. One of the frameworks for creating reports is Jasmine HTML Reporter. This generates HTML reports based on your specifications. Here is a sample report.

Supports Cloud Testing platforms: We can test our specifications across several platforms and browsers (Chrome, Firefox, Safari, etc.) thanks to cloud-based testing systems (Windows, Mac, Linux, Mobile, etc.). Major cloud testing platforms like SauceLabs and CrossBrowserTesting.com support Protractor.

Supports multiple Assertion libraries: Protractor supports a variety of assertion libraries, including Mocha, Jasmine, and your own custom libraries. Protractor utilizes the Jasmine framework by default for assertions.

Supports Control Flow: APIs are built on promises, which are controlled by control flows that have been customized for Jasmine. The entire Protractor API is asynchronous. Every function yields promises. To keep execution structured, it keeps a queue of pending promises, known as the control flow. (We will discuss Promises in greater detail in the following lesson sections.)

Supports various IDEs & Editors: You can choose from a wide variety of IDEs on the market. Visual Studio Code, WebStorm, Visual Studio Professional, Atom, and sublime are the most widely used editors. In-depth coverage will be provided in our next tutorials.

Supports CI/CD: Once automation scripts are set up, we don't need to manually run them or keep track of them. The protractor tests need to run automatically and provide you with the report each time new code is added to the repository. As a result, the process must be automated. We may do this by connecting the protractor test with build technologies like Jenkins, TFS, or Azure DevOps. Integrating build tools is supported by Protractor. (In our next lessons, we'll go over step-by-step configuration specifics.)

Advantages and limitations

Advantages

The benefits of using this open source end-to-end testing framework include:

• Protractor, an open source tool, is incredibly simple to install and set up.
• Creates tests with ease using the Jasmine framework.
• Test-driven development is encouraged (TDD).
• Has built-in waits, thus our test does not need to explicitly include waits or sleep.
• Offers all of Selenium WebDriver's benefits.
• Allows testing in parallel across many browsers.
• Offers auto-synchronization as a bonus.
• Has very quick testing times.

Limitations

The restrictions this open source end-to-end testing framework has are as follows:

• As a wrapper for WebDriver JS, it does not reveal any browser automation verticals.
• Because it is only available for JavaScript, the user must have a working knowledge of JavaScript.
• Because it is a UI driven testing tool, it only offers front-end testing.
