## What it is
Intern is a complete JavaScript testing stack supporting unit and functional testing in Node.js and browsers, with built-in code coverage, WebDriver-based cross-browser testing, and TypeScript support. It integrates with CI services like Jenkins and Travis CI and cloud testing platforms like Sauce Labs and BrowserStack.

## Use cases
- run unit tests for a JavaScript library in Node and browsers
- run functional browser tests with Selenium WebDriver
- get code coverage reports for a TypeScript project
- run tests in parallel across many browsers and platforms
- integrate JavaScript tests into Jenkins or Travis CI
- test native or hybrid mobile apps via WebDriver

## When to choose
- you need one tool for unit, functional, and cross-browser WebDriver testing
- you want built-in code coverage and TypeScript support without extra config
- you need cloud browser testing via Sauce Labs, BrowserStack, or TestingBot
- your project uses AMD modules or legacy module formats

## When to avoid
- you are starting a new project and prefer an actively developed ecosystem like Jest, Vitest, or Playwright
- you only need simple unit tests with a large community and plugin ecosystem
- you need fast-moving modern ESM-first tooling

## Facets
- artifact type: framework
- maturity: maintenance
- function: testing, e2e-testing, benchmarking
- domain: testing, web-development, developer-tools
- platform: browser, cross-platform, cli
- tags: unit-testing, functional-testing, webdriver, selenium, code-coverage, tdd, bdd, ci-integration, typescript, sauce-labs, browserstack, nodejs
