In their own words
Cucumber.js
Cucumber.js checks software against executable specifications written as plain-text scenarios, reporting whether each scenario passes or fails. It is the JavaScript implementation of Cucumber and runs on Node.js. Scenarios use Gherkin syntax and are usually kept in `.feature` files alongside the software in source control. Step definitions connect each Gherkin step to code that carries out its described action; expressions can use Cucumber Expressions or regular expressions, but not both syntaxes in a single expression.
The tool runs feature files from the command line and can run in continuous integration, including parallel execution. Reporter plugins can produce results, and reports can be published to Cucumber Reports with `--publish`. Published reports are public and deleted after 24 hours. Cucumber.js is available as the `@cucumber/cucumber` npm module, installed as a development dependency with npm or Yarn. The setup requires Node.js and one of those package managers. It is free and open source, with Linux, macOS, Windows, and self-hosted platforms listed. It works with browser automation tools, but is not itself one.
QUnit
QUnit is a free JavaScript testing framework first developed for the jQuery project. It runs in web browsers, Node.js, SpiderMonkey and Web Worker threads, so developers can test code in different runtime environments. Its APIs allow custom assertions, test runners and reporters. Browser releases have no runtime dependencies, and the project describes Node.js setup as requiring zero configuration and browser setup as minimal. For DOM tests, QUnit resets fixture markup after each test. Its browser reporter presents results and can include expected and actual values, assertion details and failure stack traces. Developers can rerun selected tests or modules and prioritize previously failing tests. Guides cover modules, asynchronous tests, callbacks and assertions, while plugins can add or modify capabilities such as DOM assertions, themes and JUnit XML reports. QUnit integrates with browser automation tools including Karma, Web Test Runner, Testem and WebdriverIO’s QUnit service. QUnit 3.0 is distributed through the jQuery CDN and npm, and is also installable with Yarn. For its ESM version, the compatibility guide lists Node.js 18+ and specified browser versions.
