Jest vs Vorlon.JS: What are the differences?

What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.

What is Vorlon.JS? An open source, extensible, platform-agnostic tool for remotely debugging and testing your JavaScript. It is a remote debugging and testing tool for JavaScript. It helps you remotely load inspect, test and debug JavaScript code running on any device with a web browser: whether it's a games console, mobile device or fridge.

Jest and Vorlon.JS can be categorized as "Javascript Testing Framework" tools.

Some of the features offered by Jest are:

Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions
Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable
Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility

On the other hand, Vorlon.JS provides the following key features:

Easy setup
Remotely connect up to 50 devices simultaneously. Run your code on each or all of them with a single click
Debug JavaScript on nearly any platform with a web environment. Plugins allow you to add new features and resources

Jest is an open source tool with 28.2K GitHub stars and 3.89K GitHub forks. Here's a link to Jest's open source repository on GitHub.

Advice on Jest, Vorlon.JS

Cypress

Jest

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.

What are some alternatives to Jest, Vorlon.JS?

Mocha

Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

Jasmine

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

Cypress

Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

CodeceptJS

It is a modern end to end testing framework with a special BDD-style syntax. The test is written as a linear scenario of user's action on a site. Each test is described inside a Scenario function with I object passed into it.

Protractor

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.

AVA

Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.

Ghost Inspector

It lets you create and manage UI tests that check specific functionality in your website or application. We execute these automated browser tests continuously from the cloud and alert you if anything breaks.

QUnit

QUnit is a powerful, easy-to-use JavaScript unit testing framework. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code, including itself!
