In their own words
FsCheck
FsCheck checks properties of.NET programs against randomly generated cases. Developers can express properties in F#, C# or VB, then run them with the built-in runner from an interactive session, a command-line program or a test framework. Integrations are documented for xUnit.net and NUnit, with user-created integrations for Expecto, Fuchu, AutoFixture and MSTest. When a property fails, FsCheck shrinks the input and shows a minimal counterexample. Developers can also define custom generators and shrinkers and group them in Arbitrary instances. The library supports parameterized cases and parallel execution, and its packages and NUnit and xUnit.NET plugins are available from NuGet. FsCheck is free: its listed plan is free, with a BSD license permitting commercial and non-commercial modification and redistribution. It runs on Linux, macOS and Windows. The project maintains version 3.x, but its documentation covers 2.x and is described as out of date and incomplete. Its model-based testing API is experimental and exempt from semantic-versioning guarantees.
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.
