## What it is
Poltergeist is a Ruby driver that lets Capybara run acceptance tests in a headless PhantomJS browser. It is effectively deprecated, with Cuprite recommended as the modern headless-Chrome-compatible replacement.

## Use cases
- run capybara tests headlessly
- headless browser testing for ruby apps
- javascript acceptance testing with capybara
- test rails app without a visible browser
- replace rack_test driver with js support

## When to choose
- maintaining a legacy Ruby test suite already using PhantomJS and Poltergeist

## When to avoid
- starting a new project - use Cuprite or Selenium with headless Chrome instead
- you need a maintained, up-to-date browser engine
- you need modern JavaScript/CSS support

## Facets
- artifact type: library

- function: testing, e2e-testing
- domain: testing, web-development, developer-tools
