11.1 Testing Strategy

11.1.1 Testing Pyramid
         ┌─────┐
        /  E2E  \      5%  - End-to-end tests
       /─────────\
      / Integration\   15% - Integration tests  
     /───────────────\
    /   Unit Tests    \80% - Unit tests
   /───────────────────\
11.1.2 Test Categories

  2. Installation Steps - Download instructions - Installation process - Initial configuration

  3. First Run - Account creation - License activation - Basic usage

16.3.2 Troubleshooting Guide
## Common Issues

### VM Fails to Start
**Symptoms**: Error message "Failed to start OpenWrt VM"

**Causes**:
1. Virtualization disabled in BIOS
2. Insufficient permissions
3. Port conflicts

**Solutions**:
1. Enable VT-x/AMD-V in BIOS settings
2. Run as Administrator
3. Check for conflicting applications

### Network Configuration Failed
**Symptoms**: "Failed to configure network adapter"

**Solutions**:
1. Reset network settings
2. Disable other VPN software
3. Restart Windows network service

16.4 Development Documentation

16.4.1 Architecture Decision Records (ADR)
# ADR-001: Use VirtualBox for Virtualization

## Status
Accepted

## Context
We need a virtualization solution that:
- Works on Windows without Hyper-V
- Has programmatic API
- Supports network bridging
- Is widely available

## Decision
Use Oracle VirtualBox with dynamic linking to VBoxC.dll

## Consequences
- **Positive**: Wide compatibility, good API
- **Negative**: Requires separate installation
- **Mitigation**: Bundle silent installer
