Testing is one of the critical processes in application development. The success or failure of the application entirely depends on it.
JavaScript testing frameworks have emerged for fulfilling different purposes, some are fit for unit testing, while others are made for end-to-end testing.
- Jest - A delightful JavaScript Testing Framework with a focus on simplicity. Jest aims to work out of the box, config free, on most JavaScript projects.
- Mocha - A feature-rich JavaScript test framework running on Node.js and in 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 - A behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.
- Cypress - A end-to-end JavaScript testing framework, built on top of Mocha, uses a BDD/TDD assertion library and a browser that can be paired with any JavaScript testing framework.
- Nightwatch.js - An integrated, easy to use End-to-End testing solution for web applications and websites, written in Node.js. It uses the W3C WebDriver API to drive browsers in order to perform commands and assertions on DOM elements.
