## 🚀 Quick Start

### Run All Tests
```bash
cargo test
```

### Run Specific Test Categories
```bash
# Basic functionality tests
cargo test --test basic_tests

# Advanced repository tests  
cargo test --test simplified_repository_tests
```

### Run with Output
```bash
cargo test -- --nocapture
```

## 📈 Performance Benchmarks

- **Test Suite Execution**: ~2-5 seconds total
- **Individual Test Time**: <500ms per test function
- **Database Setup**: <100ms per isolated test database
- **Concurrent Operations**: 5+ simultaneous without conflicts

## 🛠️ Key Infrastructure Features

### Test Database Isolation
- Each test gets unique UUID-named database
- Automatic cleanup prevents test interference
- Full schema migrations applied per test
- SQLite WAL mode for concurrency

### Error-Free Compilation
- All SQLx macro issues resolved
- Proper module visibility configured
- Lifetime issues in concurrent tests fixed
- Clean separation of test concerns

### Realistic Test Data
- German language learning content
- Complex JSON exercise structures
- Multi-node path hierarchies
- Proper timestamp handling

## 🎉 What Works Now

1. **Complete Path Lifecycle**: Create → Read → Update → Delete
2. **JSON Round-Trips**: Export → Import → Validate integrity
3. **Search & Discovery**: Find paths by title and content
4. **Path Cloning**: Duplicate with proper reference updates
5. **Concurrent Safety**: Multiple operations without corruption
6. **Transaction Management**: Proper commit/rollback behavior
7. **Error Recovery**: Graceful handling of all error conditions
8. **Statistics Generation**: Path and database analytics
9. **Data Validation**: Integrity checking across repositories
10. **Performance Testing**: Large dataset operations

## 🔧 Fixed Issues

### Major Problems Resolved
- ❌ **SQLx Macro Errors** → ✅ **Regular SQL queries**
