Over the last few years, the programming landscape has changed drastically.
Key Benefits of Mocha:
- Provides compatibility for both front-end and back-end testing
- NodeJS debugger is supported, which makes error tracing easier
- Accurate reporting
- Provides support for all browsers, including the headless Chrome library
- Very convenient framework for the developers to write test cases

Key Benefits of JEST:
- Compatible with NodeJS, React, Angular, VueJS, and other Babel-based projects
- Standard syntax with documentation support
- Very fast and highly performant
- Managing tests with larger objects is possible using Live Snapshots

Jasmine is highly beneficial for front-end testing. It includes both visibility testing and the responsiveness testing of UI across various devices with different resolutions. One can also automate user behavior with custom delay and wait time for simulating the actual user behavior.
Key Benefits of Jasmine:
- Provides small, clean, and straightforward syntax for easy testing
- Does not require any Document Object Model (DOM)
- Includes support for both front-end and back-end tests
- Ease in coding as the syntax used is very similar to a natural language
- Strong documentation and community support
Karma is another popular open-source productive testing environment. It allows a QA to perform tests for an application in different environments. Karma allows the application script to be executed on real browsers and devices like phones and tablets. Karma aims to provide a testing environment for developers wherein they don’t need to set up loads of configurations. Instead, they can just run the tests and get instant feedback.
Key Benefits of Using Karma:
- Supports integrations with top CI/CD tools like Jenkins, Travis, and Semaphore
- Tests on real devices and browsers are possible.
- Provides support for headless environments like PhantomJS
- Supports remote testing directly from a terminal or IDE
- Is framework agnostic, which means one can describe tests with popular frameworks like Mocha, and Jasmine. One can also write a simple adapter for a specific framework.
5. Puppeteer (Node Library)
Puppeteer is a Node library that provides a high-level API. This API is used to control Chrome or Chromium over the DevTools protocol. One of the major limitations of Puppeteer is the fact that it works only with Chrome and Chromium. The Puppeteer can be used for browser-specific applications like page structure tests, taking website screenshots, and more.
One can also crawl and capture pre-rendered content for Single Page Applications (SPA). Although Puppeteer has been recently introduced in the testing landscape, it has a high adoption rate, making its future promising.
Additional Benefits of Puppeteer include:
- Easy automating UI testing, form submission, and keyboard inputs
- Easy generation of screenshots and PDFs of webpages
- Support for testing Chrome extensions
- One can easily diagnose performance issues on a site using the timeline trace.

NightwatchJS is another testing framework for web applications and websites which is beneficial for end-to-end automation testing as it enables us to write end-to-end tests in node.js quickly and effortlessly. Nightwatch simplifies the process of continuous integration and set up automated tests. With Nightwatch, one can comprehend and configure the Selenium test suit and select the specific browser to execute tests. It allows parallel testing which further reduces the build time.
Key Benefits of Nightwatch include:
- Clear syntax
- Has built-in command-line test runner
- Controls standalone Selenium server in a separate child process.
- Automatically manages the WebDriver services (Edge, Safari, GeckoDriver)
- Flexible command and assertion framework
Key Benefits of Cypress:
- Simple and easy to set up
- Debug your web apps easily with Chrome dev tools directly
- Universal in nature and can test anything that runs in a web browser
- Active community on GitHub and StackOverflow
- Delivers quick test execution
