A behavior-driven development framework for testing JavaScript code. It comes with everything needed to test your code right out of the box, including assertions and mocking.

Very similar to Jest in terms of having a complete testing solution. Uses similar syntax and has built-in assertion and mocking capabilities, making it an easy switch for Jest users.

A flexible testing framework that runs on Node.js and browsers. It supports many different assertion libraries and can be used with any testing style you prefer.

Like Jest, it's a complete testing solution but more flexible in setup. Great for developers who want more control over their testing environment and prefer to choose their own assertion library.

An extremely fast and lightweight test runner for Node.js and the browser. It's designed to be simple and fast while maintaining a familiar testing API.

Perfect alternative to Vitest for projects that need super fast test execution. It's newer but gaining popularity due to its speed and simplicity.

A test runner that runs tests at the same time, which makes it really fast. It's simple to use and comes with good support for modern JavaScript features.

Great alternative if you want faster test execution through parallel testing. Perfect for projects that need quick test results and prefer a minimalist approach.

A super simple testing framework that produces a basic output format. It's very lightweight and follows the Unix philosophy of doing one thing well.

Good choice for developers who want a no-frills testing solution. It's much simpler than Jest but still powerful enough for most testing needs.
