In their own words
Kotest
Kotest is a Kotlin testing framework for JVM and Kotlin Multiplatform projects, with test styles, assertions and property testing. Its styles allow natural-language test names and unlimited nesting. The DSL supports parameterized and data-driven tests, conditional evaluation, lifecycle callbacks and parallel execution. The assertion library includes over 350 matchers, collection inspectors, soft assertions and utilities for non-deterministic code. Property tests can generate hundreds or thousands of inputs, and property testing is supported across all targets. Listed targets include JVM, JavaScript, Native, Wasm and Android unit and instrumented tests; Native includes Linux, Windows, iOS and macOS. Setup instructions cover Gradle, Maven and Kotlin Multiplatform projects. Integrations include Spring, Koin, Ktor, Allure, Testcontainers, WireMock and Micronaut. An IntelliJ plugin provides test run icons, editor results, a test explorer, structure highlighting and breadcrumbs. Kotest is free, with a free plan and no free trial. Its assertions library can also be used with JUnit, Spock or another test framework.
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.
