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. -

toxy
Hackable HTTP proxy for resiliency testing
Toxy is a programmable HTTP proxy created for resiliency testing and simulation of unreliable network conditions. It operates at the HTTP application layer, giving developers more control over requests and responses than basic TCP throttling tools. Its core model uses poisons to alter traffic and rules to decide when those alterations should apply. Tests can inject latency, limit bandwidth, return errors, manipulate payloads, or combine several adverse conditions. Rules can filter traffic by route, headers, query values, methods, bodies, and other request properties. A hierarchical middleware architecture makes the proxy extensible with custom behaviors and reusable modules. The repository was archived in 2023, so it is primarily useful as a reference or for legacy testing setups. -

Argus Eyes
A lightweight commandline tool for visual regression testing of UI
A lightweight command line tool for visual regression testing of UI components. After installing, you want to tell argus eyes which pages and which components to check for visual regression. Argus eyes work by going over a straightforward JSON file containing the resolutions you want to capture, as well as the pages with theirs url's, and the components with their CSS-selectors. Once argus eyes know where to find the components, it's time for some command line action. The first command you want to use is $ argus-eyes capture master. This makes argus eyes go over the config file and take screenshots of all specified components in there. The screenshots are saved in .argus-eyes/master and this set of screenshots can be compared with another set. -
22
Karma
Test Runner for JavaScript
The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative. Test your code on real browsers and real devices such as phones, tablets or on a headless PhantomJS instance. Control the whole workflow from the command line or your IDE - just save a file and Karma will run all the tests. Describe your tests with Jasmine, Mocha, QUnit, or write a simple adapter for any framework you like. Developed for and maintained by the open source community at GitHub. Easy debugging directly from your IDE via WebStorm or Google Chrome. Simple integration with Jenkins, Travis or Semaphore. -

SuperTest
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. -

forever
CLI tool for ensuring that a given script runs continuously
A simple CLI tool for ensuring that a given script runs continuously (i.e. forever). Note that this project currently fully depends on the community for implementing fixes and new features. For new installations we encourage you to use pm2 or nodemon. If you are using forever programmatically you should install forever-monitor. There are two ways to use forever: through the command line or by using forever in your code. Note: If you are using forever programatically you should install forever-monitor. You can use forever to run scripts continuously (whether it is written in node.js or not). In addition to passing forever the path to a script (along with accompanying options, described above), you may also pass forever the path to a JSON file containing these options. The forever module exposes some useful methods to use in your code. Each method returns an instance of an EventEmitter which emits when complete. -
