## What it is
Zombie.js is a lightweight Node.js framework for testing client-side JavaScript and full-stack web applications in a simulated headless browser environment, without launching a real browser. It provides a Browser API for visiting pages, filling forms, pressing buttons, and asserting on DOM content, and works with test frameworks like Mocha.

## Use cases
- test full-stack web apps without a real browser
- simulate user signup and form submission flows in tests
- run fast headless integration tests for client-side JavaScript
- assert on page titles and DOM text in acceptance tests
- test AJAX-driven pages in a simulated DOM environment

## When to choose
- you want fast headless browser-like tests without Selenium or a real browser
- you're testing server-rendered or lightly-scripted pages in Node.js
- you need a simple DSL for visit/fill/pressButton test flows

## When to avoid
- you need to test modern SPAs with complex JavaScript or real rendering (use Playwright or Puppeteer)
- you need to crawl untrusted web pages (explicitly unsafe per the docs)
- you need actively maintained tooling with current browser engine fidelity
