qa-device-management

Side-by-side iOS Simulator and Android Emulator control using the agent-device CLI. Manages the device lifecycle for all QA Automation skills.

When to Use

• Bringing up simulators/emulators for testing
• Launching your app on one or both platforms
• Capturing baseline or comparison screenshots
• Checking device state, app state, or accessibility tree
• Managing agent-device sessions across platforms

Configuration

All device settings are in qa.config.sh. Set these before using:

# In qa.config.sh or qa.config.local.sh:
export APP_BUNDLE_ID="com.yourapp.dev"          # Your app's bundle/package ID
export SIMULATOR_UDID="auto"                      # "auto" or specific UDID
export SIMULATOR_DEVICE_NAME="iPhone 16 Pro"      # For creating simulators
export ANDROID_AVD="Pixel_8"                       # Android AVD name
export ANDROID_SERIAL="emulator-5554"              # Android serial

Quick Start — Full Startup Sequence

Boot iOS Simulator

# Auto-detect a booted simulator, or boot one
source .pi/skills/qa-automation/qa.config.sh
UDID=$(qa_detect_simulator_udid)

# Or boot a specific one
xcrun simctl boot "$SIMULATOR_UDID" 2>&1 || true
open -a Simulator

Boot Android Emulator

nohup $EMULATOR_PATH -avd "$ANDROID_AVD" -no-snapshot-load > /tmp/qa-emu.log 2>&1 &

# Wait for boot
for i in $(seq 1 30); do
    BOOT=$($ADB_PATH shell getprop sys.boot_completed 2>/dev/null | tr -d '\r')
    if [ "$BOOT" = "1" ]; then
        echo "Android emulator booted after ~$((i*2))s"
        break
    fi
    sleep 2
done

Verify Both Devices

agent-device devices --json

Launch App on iOS

agent-device open "$APP_BUNDLE_ID" --platform ios --session default

Launch App on Android

agent-device open "$APP_BUNDLE_ID" --platform android --serial "$ANDROID_SERIAL" --session android

Capture Baseline Screenshots

agent-device screenshot /tmp/qa-ios-baseline.png --session default
agent-device screenshot /tmp/qa-android-baseline.png --session android

Session Management

agent-device binds each session to one platform. Use the correct session flag:

Platform	Session Flag	Example
iOS	--session default (or omit)	agent-device snapshot --session default
Android	--session android	agent-device snapshot --session android

# List active sessions
agent-device session list

# Release a session
agent-device close --session default

Common Operations

Screenshots (Both Platforms)

agent-device screenshot /tmp/qa-ios.png --session default
agent-device screenshot /tmp/qa-android.png --session android

Accessibility Snapshots

agent-device snapshot --session default      # iOS
agent-device snapshot --session android      # Android

# With options
agent-device snapshot -i --session default   # Interactive elements only
agent-device snapshot --depth 3              # Limit depth

Navigate and Interact

# Tap
agent-device click 200 400 --session default

# Swipe
agent-device swipe 200 800 200 200 --session default

# Scroll
agent-device scroll down --session default

# Type
agent-device fill @e3 "hello world" --session default

Go Home / Go Back

agent-device home --session default
agent-device back --session android

Check Foreground App

agent-device appstate --session default
agent-device appstate --session android

Relaunch App (Fresh State)

agent-device open "$APP_BUNDLE_ID" --session default --relaunch

Building and Installing Your App

iOS — Expo

cd "$PROJECT_DIR"
npx expo run:ios --device "$SIMULATOR_DEVICE_NAME"

iOS — React Native CLI

cd "$PROJECT_DIR"
npx react-native run-ios --simulator "$SIMULATOR_DEVICE_NAME"

Android — Expo

cd "$PROJECT_DIR"
npx expo run:android

Android — React Native CLI

cd "$PROJECT_DIR"
npx react-native run-android

Check If App Is Installed

# iOS
xcrun simctl listapps booted 2>/dev/null | grep "$APP_BUNDLE_ID"

# Android
$ADB_PATH shell pm list packages | grep "$APP_BUNDLE_ID"

Shutdown Sequence

# Close agent-device sessions
agent-device close --session default
agent-device close --session android

# Shutdown simulators
xcrun simctl shutdown "$SIMULATOR_UDID"
$ADB_PATH emu kill

CDP Connection (for React Native apps)

When coordinate-based tapping fails (e.g., full-screen video players intercept touches), use CDP to control navigation directly via the React Native Hermes runtime.

Prerequisites

• Dev server running (e.g., npx expo start)
• ws npm package available

Discover CDP Endpoints

# List available debug targets
curl -s http://localhost:$METRO_PORT/json

# Get WebSocket URL (auto-detected by qa.config.sh)
source qa.config.sh
qa_detect_cdp_ws_url

Navigate via CDP

source .pi/skills/qa-automation/qa-test-flows/lib/cdp-helpers.sh

# Navigate to a screen
cdp_navigate "SettingsScreen"

# Navigate to a tab
cdp_navigate_tab "ProfileScreen"

# Get current route
cdp_get_route

Troubleshooting

Problem	Solution
"No device found"	Verify simulator is booted: xcrun simctl list devices | grep Booted
Session bound to wrong platform	Use --session android for Android, close session and rebind
Simulator already booted (error 149)	Safe to ignore — simulator is already running
App not installed	Build and install: npx expo run:ios or npx expo run:android
agent-device click hangs	Wrap with timeout: timeout 5 agent-device click 100 200
CDP "Connection refused"	Ensure dev server is running: curl http://localhost:$METRO_PORT/status
