mobile-testing

mobile-testing is a skill for Claude Code from MonumentalSystems/Atlas-Agent-Teams. It costs 14 tokens per session (513 once invoked), scanned A, original, MIT.

A guide to testing mobile apps on real devices, simulators, and emulators. It covers iOS and Android versions, device types, networks, accessibility settings, and automated UI tests.

In plain words
What is it for?
Use it to choose mobile testing strategies, set up device-farm testing, and plan automated tests with tools such as XCUITest, Espresso, or Appium.
Why use it?
It helps teams avoid testing only one device or connection and missing problems that appear elsewhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mobile-testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mobile Testing Guidelines

Mobile Testing Strategies

  • Test on real devices when possible
  • Use simulators and emulators for initial testing
  • Test on multiple iOS and Android versions
  • Test on different screen sizes and densities
  • Test on different network conditions
  • Implement automated testing for critical paths
  • Use device farms for comprehensive coverage

Device Farm Testing

  • Use Firebase Test Lab for Android
  • Use AWS Device Farm for cross-platform testing
  • Use BrowserStack for real device testing
  • Test on popular device configurations
  • Test on older devices for performance
  • Test on different manufacturer devices (Android)
  • Test on different iOS device models

Emulator and Simulator Testing

  • Use iOS Simulator for iOS testing
  • Use Android Emulator for Android testing
  • Test on different API levels
  • Test on different screen configurations
  • Use emulator features for testing (GPS, camera, etc.)
  • Test with different language and region settings
  • Test with accessibility features enabled

UI Testing Frameworks

  • iOS: XCUITest for UI automation
  • Android: Espresso for UI testing
  • Cross-Platform: Appium for cross-platform UI tests
  • React Native: Detox for React Native testing
  • Flutter: Flutter integration testing
  • Write maintainable UI tests with page object pattern
  • Test critical user flows end-to-end

Performance Testing for Mobile

  • Measure app startup time
  • Test memory usage and detect leaks
  • Monitor battery consumption
  • Test network performance and latency
  • Test offline behavior and sync
  • Use profiling tools (Instruments, Android Profiler)
  • Set performance budgets and monitor

Mobile Accessibility Testing

  • Test with VoiceOver (iOS) and TalkBack (Android)
  • Test with Dynamic Type (iOS) and font scaling (Android)
  • Test with screen magnification
  • Verify color contrast ratios
  • Test with switch control and other assistive technologies
  • Follow WCAG and platform accessibility guidelines
  • Test with reduced motion settings

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
