## What it is
UI AutoMonkey is a JavaScript stress testing script for iOS apps that runs in Apple's UI Automation and Instruments tools, bombarding apps with random taps, swipes, rotations, and lock events. It is now deprecated because Apple removed the UI Testing instrument it depended on.

## Use cases
- stress test my iOS app with random taps and swipes
- find race conditions in an iPhone app
- monkey test an iOS application
- measure app performance under random user events
- pound my app with random gestures to find crashes

## When to choose
- you are maintaining a legacy project that still uses the old UI Automation instrument in Xcode
- you need historical reference for monkey testing approaches on old iOS toolchains

## When to avoid
- you are starting a new iOS project - Apple removed the required UI Automation instrument
- you need modern UI testing - use XCUITest or Appium instead
- you need actively maintained tooling

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: testing, e2e-testing, benchmarking
- domain: testing, mobile-development, developer-tools
- platform: -
- tags: ios, monkey-testing, stress-testing, ui-automation, instruments, deprecated, xcode, macos
