## 10.1 Best Practices Generali

### 10.1.1 Workflow Raccomandato

**Prima Esecuzione (New User)**:
```
1. Leggere questo documento (almeno Capitoli 1-5)
2. Verificare prerequisites (Python, packages)
3. Eseguire simulation mode (safe, no hardware)
   → python GRIFO_M_PBIT.py --simulate --runs 3
4. Analizzare report generati (PDF, CSV, JSON)
5. Se OK, provare hardware mode (se disponibile)
   → python GRIFO_M_PBIT.py --target --runs 1
```

**Esecuzione Regolare**:
```
1. Verificare hardware connections (se --target)
2. Eseguire test con numero runs appropriato
3. Monitorare GUI real-time per anomalie
4. Analizzare report post-test
5. Archiviare report per trend analysis
```

**Sviluppo/Debug**:
```
1. Usare --simulate per rapid iteration
2. Usare --fast-mode per skip delays
3. Usare --no-gui per headless (CI/CD)
4. Analizzare log file per detailed diagnostics
5. Test incrementali su hardware reale
```

### 10.1.2 Configurazione Ambiente

✅ **Python Environment**:
```bash
# Usa virtual environment (raccomandato)
python -m venv venv
venv\Scripts\activate  # Windows
source venv/bin/activate  # Linux/Mac

# Installa dependencies
pip install reportlab pyserial pillow
```

✅ **File Organization**:
```
TestEnvironment/
├── LOG/              # CSV files (git ignore)
├── pdf_reports/      # PDF files (git ignore)
├── json/             # Template (commit to git)
├── env/              # Source code (commit)
└── scripts/          # Test scripts (commit)
```

✅ **Git Configuration** (`.gitignore`):
```gitignore
# Test outputs (large files, regenerable)
TestEnvironment/LOG/*.csv
TestEnvironment/pdf_reports/*.pdf
*.json  # Except templates

# Python
__pycache__/
*.pyc
*.pyo
*.pyd
venv/

# IDE
.vscode/
.idea/
*.swp

# Logs
logs/
*.log
```

### 10.1.3 Logging Best Practices

**Configure Logging** (all'inizio script):
```python
import logging
import sys
from datetime import datetime

def setup_logging(log_folder: str = 'logs', level: str = 'INFO'):
    """
    Configure logging to file and console.
    
    Args:
        log_folder: Directory for log files
        level: Logging level ('DEBUG', 'INFO', 'WARNING', 'ERROR')
    """
    # Create log folder
    os.makedirs(log_folder, exist_ok=True)
    
    # Log filename with timestamp
    timestamp = datetime.now().strftime('%Y-%m-%d_%H-%M-%S')
    log_file = os.path.join(log_folder, f'GRIFO_M_PBIT_{timestamp}.log')
    
    # Configure root logger
    logging.basicConfig(
        level=getattr(logging, level.upper()),
        format='[%(asctime)s] %(levelname)-8s %(name)s: %(message)s',
        datefmt='%Y-%m-%d %H:%M:%S',
        handlers=[
            logging.FileHandler(log_file, encoding='utf-8'),
            logging.StreamHandler(sys.stdout)
        ]
    )
    
    logging.info(f"Logging initialized: {log_file}")
    return log_file

# Usage
log_file = setup_logging(log_folder='TestEnvironment/LOG', level='INFO')
```

**Logging Levels** (quando usarli):
```python
# DEBUG: Detailed diagnostic (verbose)
logging.debug(f"B6 field read: {field_name}={value}")

# INFO: Normal operation progress
logging.info(f"Starting run {run_id}/{total_runs}")

# WARNING: Unexpected but non-critical
logging.warning(f"B6 field {field_name}: Known failure (expected)")

# ERROR: Failure that affects test result
logging.error(f"B6 Check Failed: {field_name} [expected={exp}, actual={act}]")

# CRITICAL: Test cannot continue
logging.critical(f"Hardware connection lost - aborting test")
```

## 10.2 Troubleshooting Common Issues

### 10.2.1 Import Errors

**Problema**: `ModuleNotFoundError: No module named 'interpreter'`

**Causa**: Python non trova SWIG module in `PlatformSimulator/bin/`

**Soluzione**:
```python
# Verifica sys.path
import sys
print(sys.path)

# Aggiungi manualmente se necessario
sys.path.insert(0, r'C:\src\GRIFO\PlatformSimulator\bin')

# Oppure usa path bootstrap (TestEnvironment/scripts/__init__.py)
# Questo è già implementato nel wrapper
```

**Verifica**:
```python
try:
    from PlatformSimulator.bin import interpreter
    print("✓ Interpreter module loaded")
except ImportError as e:
    print(f"✗ Import failed: {e}")
```

---

**Problema**: `ImportError: DLL load failed`

**Causa**: `_interpreter.pyd` (C++ DLL) ha dipendenze mancanti

**Soluzione**:
1. Verifica Visual C++ Redistributable installato
2. Usa Dependency Walker per identificare missing DLLs
3. Copia DLLs mancanti in `PlatformSimulator/bin/`

---

### 10.2.2 Hardware Connection Issues

**Problema**: `RuntimeError: 1553 read failed`

**Diagnosi**:
```python
# Test 1: Driver loaded?
try:
    from PlatformSimulator.bin import interpreter
    print("✓ Driver module loaded")
except:
    print("✗ Driver NOT loaded")

# Test 2: Hardware responsive?
try:
    bus = interpreter.Bus1553Interface("default")
    status = bus.check_status(0x1A)
    print(f"✓ RT responsive: 0x{status:04X}")
except:
    print("✗ RT NOT responsive")
```

**Soluzioni**:
1. **Verify power**: GRIFO acceso?
2. **Check cables**: 1553 bus connesso correttamente?
3. **RT address**: Verifica `rt_address = 0x1A` è corretto
4. **Driver reset**: Riavvia PC / reinstalla driver

---

**Problema**: `Serial connection failed: [Errno 5] Access denied`

**Causa**: COM port già in uso o permission denied

**Soluzione Windows**:
```powershell
# Verifica porta in Device Manager
Get-PnpDevice | Where-Object {$_.Class -eq "Ports"}

# Chiudi programmi che usano porta
taskkill /F /IM putty.exe
taskkill /F /IM TeraTerm.exe
```

**Soluzione Linux**:
```bash
# Aggiungi user a dialout group
sudo usermod -a -G dialout $USER
# Logout/login required

# Verifica permission
ls -l /dev/ttyUSB0
```

---

**Problema**: `BrainBox connection failed: [Errno 10061] Connection refused`

**Causa**: BrainBox non raggiungibile o IP errato

**Diagnosi**:
```python
import socket

def test_brainbox_connection(ip='192.168.1.100', port=5000):
    """Test TCP connection to BrainBox"""
    try:
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sock.settimeout(2.0)
        sock.connect((ip, port))
        sock.close()
        print(f"✓ BrainBox reachable at {ip}:{port}")
        return True
    except socket.timeout:
        print(f"✗ BrainBox timeout (check network cable)")
        return False
    except socket.error as e:
        print(f"✗ BrainBox connection failed: {e}")
        return False
```

**Soluzioni**:
1. **Ping test**: `ping 192.168.1.100`
2. **Network config**: Verifica PC e BrainBox su stessa subnet
3. **Firewall**: Disabilita temporaneamente per test
4. **Power cycle**: Riavvia BrainBox

---

### 10.2.3 Test Execution Issues

**Problema**: Test bloccato su "Waiting for PBIT completion..."

**Causa**: PBIT non completa entro timeout

**Diagnosi**:
```python
# Check PBIT status manually
pbit_complete = theGrifo1553.get('pbit_complete')
print(f"PBIT Complete flag: {pbit_complete}")

# Check serial for errors
stats = theTerminal.get_statistics()
print(f"Serial fatal count: {stats['fatal_count']}")
```

**Soluzioni**:
1. **Increase timeout**: `PBIT_TIMEOUT = 300.0` (5 min)
2. **Check serial**: Fatal errors prevent PBIT completion
3. **Power cycle**: Reset GRIFO hardware
4. **Hardware issue**: PBIT genuinely failing (check diagnostics)

---

**Problema**: Tutti i run falliscono con B6 failures

**Causa**: B6 fields hanno valori inattesi

**Diagnosi**:
```python
# Read all B6 fields
b6_fields = [
    'processor_status', 'transmitter_status', 'receiver_status',
    'antenna_servo_status', 'pbit_complete', 'cooling_status'
]

print("B6 Field Values:")
for field in b6_fields:
    value = theGrifo1553.get(field)
    print(f"  {field}: {value}")
```

**Soluzioni**:
1. **Known failures**: Aggiungi a `KNOWN_FAILURES` list se atteso
2. **ICD mismatch**: Verifica expected values vs ICD documentation
3. **Hardware fault**: Genuine component failure (require maintenance)

---

**Problema**: GUI non si apre / freezes

**Causa**: Thread deadlock o Tkinter issue

**Soluzione**:
```python
# Run without GUI
python GRIFO_M_PBIT.py --simulate --no-gui

# Check for exceptions in GUI thread
# Look for errors in log file mentioning "GUI" or "Tkinter"
```

**Alternative**:
- Update Tkinter: Reinstall Python con latest version
- Run headless: `--no-gui` flag per CI/CD
- Check display: (Linux) set `DISPLAY` environment variable

---

### 10.2.4 Report Generation Issues

**Problema**: `ImportError: No module named 'reportlab'`

**Soluzione**:
```bash
pip install reportlab pillow
```

---

**Problema**: PDF vuoto o corrotto

**Diagnosi**:
```python
import os

pdf_path = 'TestEnvironment/pdf_reports/GRIFO_M_PBIT_2026-02-05_15-24-38.pdf'

# Check file exists
if not os.path.exists(pdf_path):
    print("✗ PDF file not found")
else:
    size = os.path.getsize(pdf_path)
    print(f"PDF size: {size} bytes")
    
    if size < 1024:
        print("✗ PDF suspiciously small (likely corrupt)")
    else:
        print("✓ PDF size looks OK")
```

**Soluzioni**:
1. **Check JSON data**: Verifica `json_data` dict non è vuoto
2. **ReportLab version**: Update `pip install --upgrade reportlab`
3. **Write permissions**: Verifica write access a `pdf_reports/`
4. **Disk space**: Verifica spazio disponibile su disco

---

## 10.3 Performance Optimization

### 10.3.1 Fast Mode (Simulation)

**Usa `--fast-mode` per**:
- Development rapid iteration
- CI/CD automated testing
- Smoke tests

**Effect**:
```python
if args.fast_mode:
    TELLBACK_VERIFICATION_DELAY = 0.0
    STANDBY_VERIFICATION_DELAY = 0.0
    POWER_ON_DELAY = 0.1
    
    # Skip unnecessary waits
    # Test completes in ~50% less time
```

**Benchmark**:
```
Normal Mode:  10 runs in ~8.5 minutes (51s/run)
Fast Mode:    10 runs in ~4.2 minutes (25s/run)
Speedup:      ~2x faster
```

---

### 10.3.2 Parallel Execution (Advanced)

Per testing massivo, considera parallel runs:

```python
import multiprocessing

def run_test_instance(instance_id: int, num_runs: int):
    """Run test instance (separate process)"""
    import sys
    sys.argv = ['GRIFO_M_PBIT.py', '--simulate', '--no-gui', 
                f'--runs={num_runs}']
    
    # Import and run
    from TestEnvironment.scripts import GRIFO_M_PBIT
    # ... execute test ...

if __name__ == '__main__':
    # Run 4 instances in parallel (4 cores)
    num_instances = 4
    runs_per_instance = 25
    
    with multiprocessing.Pool(num_instances) as pool:
        pool.starmap(run_test_instance, 
                    [(i, runs_per_instance) for i in range(num_instances)])
    
    # Total: 4 * 25 = 100 runs
    # Time: ~same as 25 runs (parallelized)
```

**Note**: Solo per simulation mode (hardware mode richiede serialization)

---

### 10.3.3 Batch Processing

Per long-duration testing:

```bash
# Windows batch file: run_overnight.bat
@echo off
for /L %%i in (1,1,10) do (
    echo Running batch %%i of 10...
    python GRIFO_M_PBIT.py --simulate --runs 50 --no-gui
    timeout /t 60 /nobreak
)
echo All batches complete.
```

```bash
# Linux shell script: run_overnight.sh
#!/bin/bash
for i in {1..10}; do
    echo "Running batch $i of 10..."
    python GRIFO_M_PBIT.py --simulate --runs 50 --no-gui
    sleep 60
done
echo "All batches complete."
```

---

## 10.4 Debugging Techniques

### 10.4.1 Enable Debug Logging

```python
# Change logging level to DEBUG
setup_logging(level='DEBUG')

# OR via environment variable
import os
os.environ['GRIFO_LOG_LEVEL'] = 'DEBUG'
```

**Output**:
```
[2026-02-05 15:24:38] DEBUG    leo_grifo_1553: B6 field read: processor_status=1
[2026-02-05 15:24:38] DEBUG    leo_grifo_1553: B6 field read: transmitter_status=1
[2026-02-05 15:24:38] INFO     GRIFO_M_PBIT: B6 checks: 11 PASS, 0 FAIL, 1 KNOWN
```

---

### 10.4.2 Interactive Debugging

**Python Debugger (pdb)**:
```python
import pdb

# Set breakpoint
pdb.set_trace()

# Commands:
# n - next line
# s - step into
# c - continue
# p <var> - print variable
# l - list code
# q - quit
```

**VS Code Debugging**:
```json
// .vscode/launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "GRIFO Simulate",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder}/TestEnvironment/scripts/GRIFO_M_PBIT.py",
            "args": ["--simulate", "--runs", "3"],
            "console": "integratedTerminal",
            "cwd": "${workspaceFolder}"
        }
    ]
}
```

---

### 10.4.3 Mock Object Inspection

**Durante simulation, ispeziona mock state**:
```python
# Access mock object
mock_1553 = theGrifo1553  # Already MockGrifo1553Interface

# Inspect overrides
print(f"B6 overrides: {mock_1553.b6_overrides}")
print(f"Target config: {mock_1553.target_config}")

# Manually set field for testing
mock_1553.b6_values['processor_status'] = 0  # Force failure
```

---

### 10.4.4 Post-Mortem Analysis

**Analizza test falliti**:
```python
import json

# Load JSON output
with open('TestEnvironment/LOG/GRIFO_M_PBIT_2026-02-05_15-24-38.json') as f:
    data = json.load(f)

# Find failed runs
failed_runs = [r for r in data['runs'] if r['result'] == 'FAIL']

print(f"Failed runs: {len(failed_runs)}")
for r in failed_runs:
    print(f"\nRun {r['run_id']}:")
    for failure in r.get('failures', []):
        print(f"  - {failure}")
```

---

## 10.5 Manutenzione e Estensione

### 10.5.1 Aggiornare ICD (Interface Control Document)

**Quando**: Nuovo firmware GRIFO cambia B6/B8 fields

**Step**:
1. **Update field definitions** in `leo_grifo_1553.py`:
```python
self.b6_fields = {
    'processor_status': 0x00,
    # ... existing fields ...
    'new_field_name': 0x0C,  # New field at offset 12
}
```

2. **Update expected values** in test script:
```python
def check_b6_status():
    # ... existing checks ...
    
    # New field check
    result = check_field('new_field_name', expected=1)
    if not result:
        failures.append('new_field_name')
```

3. **Update mock** in `GRIFO_M_PBIT_mock.py`:
```python
MOCK_B6_DEFAULTS = {
    # ... existing ...
    'new_field_name': 1  # Default value
}
```

4. **Test**: Run simulation to verify new field tracked correctly

---

### 10.5.2 Aggiungere Nuovi Test Phases

**Scenario**: Aggiungere test di calibrazione dopo PBIT

**Implementation**:
```python
def test_calibration_phase():
    """New test phase: calibration verification"""
    logging.info("Starting calibration phase...")
    
    # 1. Set calibration mode
    theGrifo1553.set('CALIBRATION_MODE', 1)
    time.sleep(2.0)
    
    # 2. Check calibration status
    cal_status = theGrifo1553.get('calibration_status')
    if cal_status != 1:
        logging.error("Calibration failed")
        return False
    
    # 3. Read calibration data
    cal_data = theGrifo1553.read_calibration_data()
    
    logging.info("Calibration phase complete")
    return True

# Add to main test loop
def main_test():
    for run in range(1, num_runs+1):
        power_cycle_grifo()
        
        pbit_ok = test_pbit_phase()
        if not pbit_ok:
            continue
        
        b6_ok = test_b6_phase()
        b8_ok = test_b8_phase()
        
        # NEW: Calibration phase
        cal_ok = test_calibration_phase()
        
        serial_ok = test_serial_phase()
        target_ok = test_target_phase()
        
        # Evaluate result (include cal_ok)
        # ...
```

---

### 10.5.3 Custom Report Templates

**Personalizzare PDF Layout**:
```python
# File: TestEnvironment/env/leo_grifo_test_report.py

def generate_pdf_report_custom(output_folder: str, json_data: Dict) -> str:
    """Custom PDF report with company branding"""
    
    # ... standard setup ...
    
    # Add company logo
    from reportlab.lib.utils import ImageReader
    logo = ImageReader('company_logo.png')
    story.append(Image(logo, width=2*inch, height=1*inch))
    
    # Add custom header
    custom_header = Paragraph(
        "GRIFO M-PBIT Test Report - Confidential",
        custom_style
    )
    story.append(custom_header)
    
    # ... rest of report ...
```

                to: 'test-team@company.com'
            )
        }
    }
}
```

## 10.7 FAQ

### Q1: Posso eseguire test su più GRIFO contemporaneamente?

**A**: Sì, ma richiede modifiche:
1. Ogni GRIFO deve avere **RT address unico** (0x1A, 0x1B, ecc.)
2. Ogni istanza test deve usare **porta seriale separata**
3. BrainBox deve controllare **relay separati** per ciascun GRIFO
4. Usa **process isolation** (multiprocessing) per evitare conflitti

---

### Q2: Come integro con sistema di tracking bug?

**A**: Aggiungi logging structured:
```python

### Q3: Come archivio report per compliance?

**A**: Usa versioning e database:
```python
import shutil
import sqlite3
from datetime import datetime

def archive_report(pdf_path: str, csv_path: str, json_path: str):
    """Archive reports to compliance database"""
    
    # Create archive folder with date
    archive_root = r'\\network\share\GRIFO_Reports'
    date_folder = datetime.now().strftime('%Y-%m')
    archive_path = os.path.join(archive_root, date_folder)
    os.makedirs(archive_path, exist_ok=True)
    
    # Copy files
    for src in [pdf_path, csv_path, json_path]:
        dst = os.path.join(archive_path, os.path.basename(src))
        shutil.copy2(src, dst)
    
    # Log to database
    conn = sqlite3.connect('test_archive.db')
    cursor = conn.cursor()
    cursor.execute("""
        INSERT INTO test_runs (timestamp, pdf_path, csv_path, json_path)
        VALUES (?, ?, ?, ?)
    """, (datetime.now(), pdf_path, csv_path, json_path))
    conn.commit()
    conn.close()
```

### Q4: È possibile testare solo B6 o solo B8?

**A**: Sì, commenta le fasi non necessarie:
```python
def main_test():
    for run in range(1, num_runs+1):
        power_cycle_grifo()
        
        pbit_ok = test_pbit_phase()
        
        b6_ok = test_b6_phase()  # Keep this
        # b8_ok = test_b8_phase()  # Comment out
        # serial_ok = test_serial_phase()  # Comment out
        # target_ok = test_target_phase()  # Comment out
        
        result = 'PASS' if b6_ok else 'FAIL'
```

---

### Q5: Come cambiare lingua report (Italiano → Inglese)?

**A**: Modifica stringhe in `leo_grifo_test_report.py`:
```python
# OLD (Italian)
title = Paragraph("GRIFO M-PBIT TEST REPORT", title_style)

# NEW (English)
title = Paragraph("GRIFO M-PBIT TEST REPORT", title_style)

# Use constant dict for localization
STRINGS = {
    'IT': {
        'title': 'RAPPORTO TEST GRIFO M-PBIT',
        'run': 'Esecuzione',
        'passed': 'Superati',
        'failed': 'Falliti'
    },
    'EN': {
        'title': 'GRIFO M-PBIT TEST REPORT',
        'run': 'Run',
        'passed': 'Passed',
        'failed': 'Failed'
    }
}

# Select language
LANG = 'EN'
title = Paragraph(STRINGS[LANG]['title'], title_style)
```
