## What it is
CasperJS is a navigation scripting and testing utility for the PhantomJS and SlimerJS headless browsers, providing high-level APIs for defining navigation scenarios, filling forms, capturing screenshots, and writing functional test suites. It is no longer actively maintained.

## Use cases
- scrape pages with a headless browser
- write functional test suites for web pages
- fill and submit forms automatically
- capture screenshots of pages or page areas
- assert on remote DOM elements
- export test results as JUnit XML

## When to choose
- you must maintain a legacy test suite already written for PhantomJS or SlimerJS
- you need to keep old production tests running on PhantomJS 1.9 or 2.x

## When to avoid
- starting a new browser automation or testing project
- you need modern browser support (Chromium/Firefox via Playwright, Puppeteer, or Selenium)
- you want an actively maintained tool with security fixes

## Facets
- artifact type: library
- maturity: abandoned
- function: testing, e2e-testing, web-scraping, http-client
- domain: testing, developer-tools, web-development
- platform: cross-platform, cli
- tags: phantomjs, slimerjs, headless-browser, navigation-scripting, scraping, unmaintained, automation, nodejs
