JavaScript is one of the most popular open-source platforms. In this expert series, we would like to bring the concepts that help you to understand, how one can automate React and Angular JS-based web applications.
The following survey by GitHub shows that JavaScript has topped the charts for most popular language, with maximum pull requests in the last year by owning 2.3 million projects.
JavaScript has entered a revolutionary era where web developers are writing code for both client and server side using JS. This eventually facilitates resource re-usability and saves the time and cost of development.
The reason behind JavaScript being crowned as a pick up language is the simplicity and flexibility it carries for both client and server side. Typically, Node.js is being used in order to execute JavaScript at back-end. The collaboration between JavaScript and Node.js makes the modern JavaScript an ideal choice for real-time web applications.
There are multiple modern JavaScript frameworks in the market. The following trend shows that top three front-end JavaScript frameworks are React.js, Vue.js, and Angular.js.
JavaScript based applications load their content without refreshing. So, the content is dynamic in nature. Hence, tracing the UI modifications and locating elements is a challenge.
Challenges with traditional automation tools
Good amount of customization and efforts are required by the traditional tools, for automating apps based on modern JS.
To identify locators in compound class used in JavaScript, we have to use Xpath which is not a recommended approach.
Front-End UI Framework
React.js
Angular.js
Mocha, Nightwatch, Jasmine, Jest, Enzyme, Protractor
Protractor, Karma, Mocha, Jasmine
Automation Technologies
Mocha is a JavaScript testing framework which runs on Node.js and executes asynchronous code. It executes tests serially and maps the exceptions to corresponding test cases. Official website is “http://mochajs.org”.
Mocha includes Test runner and API for setting up suites. It is fast as it runs on Node.js, easier to setup, convenient, supports both TDD and BDD, and supports all kinds of unit and functional tests.
