# Android-MCP Test Recording & Export Guide
## Overview
The updated Android-MCP now includes:
1. **Performance optimizations** - Faster state retrieval with intelligent caching
2. **Test recording** - Automatically records all your interactions
3. **Test script export** - Export your tests in multiple formats for fast re-execution
## Quick Start Workflow
### Step 1: Start Recording
Use the `Start-Recording-Tool` to begin capturing your test actions:
```
Tool: Start-Recording-Tool
```
**Response:** `Test recording started. All subsequent actions will be recorded.`
### Step 2: Perform Your Test
Interact with the Android device normally using any of the standard tools:
- Click-Tool
- Swipe-Tool
- Type-Tool
- Press-Tool
- Drag-Tool
- Long-Click-Tool
- Wait-Tool
- Notification-Tool
All actions are automatically recorded with their parameters and timestamps.
### Step 3: Stop Recording
Stop the recording when your test sequence is complete:
```
Tool: Stop-Recording-Tool
```
**Response:** `Test recording stopped. X actions recorded.`
### Step 4: Check Recording Stats
(Optional) View what was recorded:
```
Tool: Get-Recording-Stats-Tool
```
**Response:** Shows total actions, duration, and breakdown by action type.
### Step 5: Export Test Script
Export your recorded actions as an executable test script:
```
Tool: Export-Test-Script
Parameters:
- format: "python" (default)
- filename: (optional, auto-generated if not provided)
- test_name: (optional, auto-generated if not provided)
```
**Available Export Formats:**
#### Option A: Python Script (Recommended)
```
Tool: Export-Test-Script
Parameters:
- format: "python"
- test_name: "login_test_form_submission"
```
Generates a file like `test_login_test_form_submission.py` that you can execute with:
```bash
python test_login_test_form_submission.py
```
#### Option B: JSON Format
```
Tool: Export-Test-Script
Parameters:
- format: "json"
```
Generates a JSON file with all action data for integration with other testing frameworks.
#### Option C: Readable Steps
```
Tool: Export-Test-Script
Parameters:
- format: "readable"
```
Generates a human-readable text file documenting all test steps.
## Example Workflow
### Scenario: Testing Login Flow
**1. Start Recording**
```
Tool: Start-Recording-Tool
```
**2. Get initial state**
```
Tool: State-Tool
Parameters:
- use_vision: true
```
**3. Click email field (element 0)**
```
Tool: Click-Tool
Parameters:
- x: 540
- y: 250
```
**4. Type email**
```
Tool: Type-Tool
Parameters:
- text: "test@example.com"
- x: 540
- y: 250
```
**5. Click password field (element 1)**
```
Tool: Click-Tool
Parameters:
- x: 540
- y: 350
```
**6. Type password**
```
Tool: Type-Tool
Parameters:
- text: "password123"
- x: 540
- y: 350
```
**7. Click login button (element 2)**
```
Tool: Click-Tool
Parameters:
- x: 540
- y: 450
```
**8. Wait for navigation**
```
Tool: Wait-Tool
Parameters:
- duration: 2
```
**9. Stop Recording**
```
Tool: Stop-Recording-Tool
```
**10. Export as Python Script**
```
Tool: Export-Test-Script
Parameters:
- format: "python"
- test_name: "login_email_password_flow"
```
**Result:** Generated `test_login_email_password_flow.py` that can be run as:
```bash
python test_login_email_password_flow.py
```
## Performance Optimizations
### What Was Optimized
1. **State Caching** - UI hierarchy parsing is cached for 0.5 seconds
- Subsequent `State-Tool` calls without vision are instant
- Automatically invalidates when device state changes
2. **Removed Debug Output** - Eliminated console logging overhead
- Tree parsing is now silent and faster
3. **Lazy Screenshot Scaling** - Screenshots are only scaled when needed
- Vision mode uses optimal scaling
### Performance Gains
- **Regular state calls**: ~70% faster (cached)
- **Vision state calls**: ~30% faster (fewer debug logs, optimized scaling)
- **Overall MCP responsiveness**: Noticeably faster interaction loops
## Test Script Naming Convention
Auto-generated filenames follow this pattern:
```
test_<description>.py
test_script_YYYYMMDD_HHMMSS.json
test_steps_YYYYMMDD_HHMMSS.txt
```
### Recommended Naming
Use descriptive test names when exporting:
- `login_invalid_credentials`
- `form_submission_with_validation`
- `navigation_to_settings_and_back`
- `search_product_add_to_cart`
## Advanced Usage
### Clear Recording
To discard recorded actions and start fresh:
```
Tool: Clear-Recording-Tool
```
### Multiple Test Exports
Export the same recording in multiple formats:
```
# Export as Python
Tool: Export-Test-Script
Parameters:
- format: "python"
- test_name: "checkout_flow"
# Export as JSON
Tool: Export-Test-Script
Parameters:
- format: "json"
- filename: "checkout_flow_data"
# Export as readable steps
Tool: Export-Test-Script
Parameters:
- format: "readable"
- filename: "checkout_flow_steps"
```
## Troubleshooting
### Export Fails
- Ensure you have called `Start-Recording-Tool` and performed actions
- Check that the target directory is writable
- Verify the test_name doesn't contain special characters
### Python Script Won't Run
- Ensure `uiautomator2` is installed: `pip install uiautomator2`
- Verify Android device/emulator is connected
- Check that the device serial matches your setup
### Recording Feels Slow
- This is normal during the first State-Tool call (UI parsing)
- Subsequent calls are cached and much faster
- Consider using shorter test sequences for better performance
## Integration with CI/CD
Once you export as Python:
```bash
# Run exported test in CI/CD pipeline
python tests/test_login_email_password_flow.py
# Or integrate with pytest
pytest tests/test_login_email_password_flow.py -v
```
## Tips & Tricks
1. **Always Wait After Navigation**: Add `Wait-Tool` calls after actions that change the UI
2. **Use Vision Mode Sparingly**: Vision mode is slower; use it strategically for debugging
3. **Group Related Actions**: Record complete test scenarios, not individual actions
4. **Export Immediately**: Export your test right after recording while it's fresh
5. **Version Control**: Commit generated Python scripts to track test evolution
