AVA is a test runner for Node.js that’s minimal and fast, and lets you develop with confidence. AVA is equipped with a concise API, detailed error output, process isolation and many other great features that set it apart from others. It is able to run tests concurrently, enforces the writing of atomic tests and includes TypeScript definitions. One of the key features it has is Magic Assert, wherein only certain values are displayed and highlighted for better viewing and easier comparison. It automatically removes unrelated lines in stack traces, and also automatically detects whether your CI environment supports parallel builds.
AVA is currently available in a number of different translations. To keep up to date with its latest developments, you can follow the official AVA Twitter account: https://twitter.com/ava__js
