## What it is
Nodeunit is a unit testing framework for Node.js and the browser, built on the assert module with support for asynchronous tests, setUp/tearDown, and multiple reporters. The project is officially deprecated and users are encouraged to adopt actively maintained alternatives like Mocha, Jest, or tape.

## Use cases
- run unit tests for node.js modules
- test asynchronous code in node
- run unit tests in the browser
- export tests from a module and run them with a CLI runner
- generate jUnit XML or HTML test reports
- use mocks and stubs in tests

## When to choose
- maintaining a legacy codebase that already uses nodeunit
- you need a minimal, assert-based test style with no new dependencies

## When to avoid
- starting any new node.js project
- you need an actively maintained testing framework
- you want modern features like snapshot testing or parallel execution

## Facets
- artifact type: library
- maturity: abandoned
- function: testing
- domain: testing, developer-tools, web-development
- platform: browser
- tags: unit-testing, async-testing, deprecated, test-runner, assertions, nodejs, javascript
