## What it is
Chrome for Testing is a Google-maintained distribution of versioned Chrome, ChromeDriver, and chrome-headless-shell binaries for automated testing, plus a JSON API and dashboard listing available versions and download URLs per channel and platform. It ensures reproducible, matching browser/driver versions for automation workflows.

## Use cases
- download a specific Chrome version for automated tests
- pin matching chromedriver and chrome binaries in CI
- bisect a browser regression across Chrome versions
- fetch latest stable Chrome for Testing via JSON API
- install chrome-headless-shell for headless scraping or testing

## When to choose
- you need reproducible, version-pinned Chrome binaries for Selenium, Puppeteer, or Playwright-style automation
- you want a programmatic JSON API to resolve browser download URLs
- you need to bisect bugs across many Chrome builds

## When to avoid
- you just need a regular end-user Chrome browser
- you need browsers other than Chrome
- you want a testing framework rather than browser binaries
