Brittle Test Runner

Brittle is a lightweight, modern TAP (Test Anything Protocol) test runner for JavaScript, currently stable at version 3.19.1. It provides a clean API for writing both classic callback-based and modern async/await tests, supporting features like test plans, subtests, explicit exception/execution checks, and utilities for timeouts and teardowns. A key differentiator is its support for multiple JavaScript runtimes, including Node.js, Bare, and Pear, making it suitable for a wide range of environments. While a strict release cadence isn't published, it appears to be actively maintained with regular updates. Brittle aims to be a robust yet simple testing solution, focusing on developer experience and modern JavaScript paradigms without the overhead of larger test frameworks.
