A feature-rich JavaScript test framework running on Node.js
Mocha is 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. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.
Nodeunit is a lightweight and simple unit testing framework for Node.js that follows a minimalistic approach inspired by traditional xUnit testing patterns. It allows developers to write test cases as plain JavaScript functions, making it easy to integrate into existing projects without requiring complex setup or configuration. The framework provides basic assertion methods and test runners that can execute tests sequentially or asynchronously. Nodeunit supports both synchronous and asynchronous tests, enabling developers to validate code that relies on callbacks or promises. It also includes features for grouping tests into modules and organizing test suites for better structure and readability. The output is designed to be clear and informative, helping developers quickly identify failing tests and debug issues.

Super-agent driven library for testing node.js HTTP servers
A super-agent driven library for testing node.js HTTP servers using a fluent API. The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent. Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion.
Appium is an open source test automation framework for use with native, hybrid and mobile web apps. It drives iOS, Android, and Windows apps using the WebDriver protocol. Is native app automation missing from your tool belt? Problem solved. Appium is built on the idea that testing native apps shouldn't require including an SDK or recompiling your app. And that you should be able to use your preferred test practices, frameworks, and tools. Appium is an open source project and has made design and tool decisions to encourage a vibrant contributing community. Appium aims to automate any mobile app from any language and any test framework, with full access to back-end APIs and DBs from test code. Write tests with your favorite dev tools using all the above programming languages, and probably more (with the Selenium WebDriver API and language-specific client libraries).
A statistical analysis tool for performance testing
Hiper is an open-source command-line tool designed for statistical analysis of web performance and page load behavior during performance testing. The tool repeatedly loads a specified webpage multiple times and gathers detailed timing metrics in order to produce more reliable performance measurements than single-run benchmarks. By averaging data across multiple page loads, Hiper helps developers understand whether performance optimizations actually improve real-world page loading behavior. The tool relies on browser performance timing data to capture metrics such as DNS lookup time, TCP connection time, time to first byte, download duration, DOM readiness, and total page load time. Hiper runs from the command line and can be installed globally using Node.js package managers, making it simple to integrate into development or testing workflows.
