| Coverage | Intern provides code coverage reporting. | The README documents coverage with c8 for Node.js and Deno and identifies browser coverage as a limitation because bundling with esbuild loses source mapping. |
| Install | The homepage links to GitHub downloads and says to install Intern with `npm install intern`. | The README gives npm and Deno installation commands and requires Node.js 22 or later or Deno 2 or later. |
| License | The homepage identifies Intern as New BSD licensed. | The repository identifies its license as MIT. |
| Maker | The product site says Intern is created by SitePen and © 2022 OpenJS Foundation. | The repository identifies izelnakri as its owner and describes QUnitX as a project by its maker; it provides no headquarters or founding date in the opened pages. |
| Purpose | Intern is a JavaScript testing framework for websites and applications. | QUnitX lets teams write one JavaScript or TypeScript test file and run it unchanged with Node.js, Deno, or in a browser. |
In their own words
Intern
Intern is a free, open-source test system for JavaScript libraries and applications. It supports unit and functional testing, with tests written in JavaScript or TypeScript using TDD or BDD styles. Tests can run in Node.js, web browsers, or across multiple browsers and platforms through the Intern runner, with parallel execution and code coverage reporting. The project can target web pages and native or hybrid iOS and Android applications. For browser automation, it supports WebDriver-compatible tools and services, including Selenium, Appium, and Selendroid. Listed cloud options include Sauce Labs, BrowserStack, TestingBot, and a user’s own Selenium Grid. Continuous-integration integrations include Travis CI, Jenkins, and TeamCity. Intern’s extensible architecture allows custom test interfaces, executors, and reporters. It runs on Android, iOS, Linux, macOS, self-hosted environments, the web, and Windows. Installation is provided through npm, and the project uses the New BSD license.
QUnitX
QUnitX lets teams write JavaScript or TypeScript tests in one file and run them with Node.js, Deno, or in a browser. The project says it needs no configuration files, transform pipeline, injected globals, or runtime dependencies, and that TypeScript runs as-is. Its assertions cover deep and partial equality, error matching, ordered steps, assertion counts, and per-test timeouts. Tests can be organized in nested modules with before, beforeEach, afterEach, and after hooks. The browser interface filters tests, shares filtered views by URL, reruns individual tests, and displays assertion differences. The linked qunitx-cli runs tests in headless Chromium, Firefox, or WebKit and streams TAP output. It also supports esbuild plugins, GitHub-annotated output, JUnit XML, V8 coverage reports, and a JavaScript API. QUnitX is free and lists an MIT license. The core requires Node.js 22 or later or Deno 2 or later; the CLI requires Node.js 24 or later or Deno 2.7 or later. Its default standalone Chromium mode also needs system Chrome or CHROME_BIN. Browser coverage has a source-map limitation.
