# JSON Structure Documentation
Diese Dokumentation erklärt die JSON-Struktur für Lernpfade in der Flalingo-Anwendung.
## Übersicht
Ein Lernpfad (Path) besteht aus mehreren hierarchischen Elementen:
- **Path**: Der Hauptcontainer für einen Lernkurs
- **Metadata**: Versionierung und Zeitstempel
- **Nodes**: Lerneinheiten innerhalb des Pfads
- **Exercises**: Einzelne Übungen innerhalb der Nodes
## JSON Schema
### Path (Hauptstruktur)
```json
{
"id": "string", // Eindeutige Pfad-ID
"title": "string", // Titel des Lernpfads
"description": "string", // Beschreibung des Pfads
"metadata": [...], // Array von Metadata-Objekten
"nodes": [...] // Array von Node-Objekten
}
```
### Metadata
```json
{
"path_id": "string", // Referenz zur Pfad-ID
"version": "string", // Versionsnummer (z.B. "1.0.0")
"created_at": "string", // ISO 8601 Timestamp
"updated_at": "string" // ISO 8601 Timestamp
}
```
### Node (Lerneinheit)
```json
{
"id": number, // Eindeutige Node-ID (Zahl)
"title": "string", // Titel der Lerneinheit
"description": "string", // Beschreibung der Einheit
"path_id": "string", // Referenz zur übergeordneten Pfad-ID
"exercises": [...] // Array von Exercise-Objekten
}
```
### Exercise (Übung)
```json
{
"id": number, // Eindeutige Exercise-ID (Zahl)
"ex_type": "string", // Typ der Übung (siehe Exercise-Typen)
"content": "string", // JSON-String mit übungsspezifischen Daten
"node_id": number // Referenz zur übergeordneten Node-ID
}
```
## Exercise-Typen
Das `content`-Feld enthält einen JSON-String, dessen Struktur je nach `ex_type` variiert:
### vocabulary
Vokabel-Lernkarten
```json
{
"word": "hola",
"translation": "hallo",
"audio": "hola.mp3",
"image": "greeting.jpg",
"context": "informal greeting",
"gender": "feminine", // für gendered Sprachen
"type": "greeting" // Kategorie
}
```
### multiple_choice
Multiple-Choice Fragen
```json
{
"question": "Was bedeutet 'apple'?",
"options": ["Apfel", "Birne", "Orange", "Banane"],
"correct": 0, // Index der richtigen Antwort
"explanation": "Apple = Apfel auf Deutsch"
}
```
### fill_blank
Lückentexte
```json
{
"sentence": "The cat ___ on the table",
"answer": "is",
"options": ["is", "are", "was", "were"], // optional
"hint": "Verb 'to be' in 3rd person singular"
}
```
### translation
Übersetzungsübungen
```json
{
"source": "I am happy",
"target": "Ich bin glücklich",
"language_pair": "en-de",
"hints": ["I = Ich", "am = bin", "happy = glücklich"]
}
```
### grammar
Grammatik-Erklärungen und -Übungen
```json
{
"rule": "Present tense of 'ser'",
"explanation": "Das Verb 'ser' (sein) im Präsens",
"examples": ["Yo soy estudiante", "Tú eres profesor"],
"conjugations": [
{"person": "yo", "form": "soy"},
{"person": "tú", "form": "eres"}
]
}
```
### pronunciation
Ausspracheübungen
```json
{
"phrase": "Me llamo...",
"phonetic": "me ˈʎamo",
"audio": "me_llamo.mp3",
"tip": "Das 'll' wird wie 'j' ausgesprochen",
"speed": "normal" // slow, normal, fast
}
```
### matching
Zuordnungsübungen
```json
{
"pairs": [
{"left": "hermano", "right": "Bruder"},
{"left": "hermana", "right": "Schwester"},
{"left": "padre", "right": "Vater"}
],
"instruction": "Ordne die spanischen Wörter den deutschen zu"
}
```
### listening
Hörverständnisübungen
```json
{
"audio": "dialogue.mp3",
"question": "Was sagt die Frau?",
"options": ["Ich bin müde", "Ich bin hungrig", "Ich bin glücklich"],
"correct": 1,
"transcript": "Tengo hambre" // optional
}
```
### sentence_building
Sätze zusammensetzen
```json
{
"words": ["Yo", "soy", "estudiante", "de", "medicina"],
"correct_order": ["Yo", "soy", "estudiante", "de", "medicina"],
"translation": "Ich bin Medizinstudent",
"shuffled": true // Wörter werden gemischt dargestellt
}
```
### image_selection
Bildauswahl
```json
{
"instruction": "Wähle das rote Auto",
"images": ["red_car.jpg", "blue_car.jpg", "green_car.jpg"],
"correct": "red_car.jpg",
"audio": "red_car_audio.mp3" // optional
}
```
### conversation
Dialogübungen
```json
{
"scenario": "Im Restaurant bestellen",
"dialogue": [
{"speaker": "waiter", "text": "¿Qué desea ordenar?"},
{"speaker": "customer", "text": "Quiero una pizza, por favor"},
{"speaker": "waiter", "text": "¿Algo para beber?"}
],
"user_role": "customer",
"context": "formal restaurant setting"
}
```
## Datentypen und Validierung
### Pflichtfelder
- Alle `id` Felder sind erforderlich und müssen eindeutig sein
- `title` und `description` sind immer erforderlich
- `content` muss ein gültiger JSON-String sein
### Referenzielle Integrität
- `metadata.path_id` muss mit `path.id` übereinstimmen
- `node.path_id` muss mit `path.id` übereinstimmen
- `exercise.node_id` muss mit `node.id` übereinstimmen
### Zeitstempel
Alle Zeitstempel müssen im ISO 8601 Format vorliegen:
```
"2024-01-20T10:30:00Z"
```
## Beispiel-Dateien
- `example_path.json` - Vollständiger Spanisch-Anfängerkurs
- `example_path_simple.json` - Vereinfachtes Beispiel mit grundlegenden Typen
## Erweiterbarkeit
Das System ist so konzipiert, dass neue Exercise-Typen einfach hinzugefügt werden können:
1. Neuen `ex_type` definieren
2. Entsprechende `content`-Struktur dokumentieren
3. Repository-Layer unterstützt automatisch neue Typen

This directory contains comprehensive tests for the Flalingo language learning application's Rust backend.
## 🏗️ Test Structure
### Current Working Tests
```
tests/
├── common/
│ └── mod.rs # Shared test utilities and database setup
├── basic_tests.rs # Basic functionality and integration tests
├── simplified_repository_tests.rs # Repository CRUD operations and advanced features
└── README.md # This documentation
```
### Test Categories
#### 1. **Basic Tests** (`basic_tests.rs`)
- Database connection and health checks
- Simple CRUD operations for paths
- JSON import/export functionality
- Search capabilities
- Error handling scenarios
- Path cloning operations
#### 2. **Repository Tests** (`simplified_repository_tests.rs`)
- Comprehensive repository testing including:
- Metadata repository operations
- Path repository full CRUD lifecycle
- Repository manager coordination
- Transaction handling (commit/rollback)
- Concurrent operations safety
- Complex path structures with multiple nodes/exercises
## 🧪 Test Infrastructure
### Test Database (`common/TestDb`)
Each test uses an isolated SQLite database that is:
- Created with a unique UUID identifier
- Automatically migrated with the latest schema
- Cleaned up after test completion
- Located in `./test_dbs/` directory
### Key Features
- **Isolation**: Each test gets its own database instance
- **Cleanup**: Automatic cleanup prevents test interference
- **Migrations**: Uses real SQLx migrations for authentic schema
- **Concurrent Safe**: Tests can run in parallel safely
### Test Data Helpers
Pre-built test data generators in each test file for:
- `create_test_path()` - Complete learning path with nodes and exercises
- `create_test_metadata(path_id, version)` - Metadata with proper timestamps
- `create_simple_test_path()` - Minimal valid path for basic testing
## 🚀 Running Tests
### Prerequisites
```bash
# Install Rust and Cargo (if not already installed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Navigate to project directory
cd flalingo/src-tauri
```
### Test Commands
#### Run All Tests
```bash
cargo test
```
#### Run Specific Test Files
```bash
# Basic functionality tests
cargo test --test basic_tests
# Repository and advanced tests
cargo test --test simplified_repository_tests
```
#### Run Tests with Output
```bash
# Show test output (including println! statements)
cargo test -- --nocapture
# Run tests verbosely
cargo test --verbose
# Run single test function
cargo test test_simple_path_crud -- --nocapture
```
#### Run Tests in Release Mode (for performance testing)
```bash
cargo test --release
```
## 📊 Test Coverage
### Current Test Coverage
#### Database Operations
- ✅ **Connection Management**: Health checks, connection pooling
- ✅ **Schema Migrations**: Automatic migration application
- ✅ **Transaction Handling**: Commit/rollback scenarios
- ✅ **Concurrent Access**: Multi-threaded database safety
#### Repository Operations
- ✅ **Path CRUD**: Complete Create, Read, Update, Delete lifecycle
- ✅ **Metadata Management**: Version tracking and timestamps
- ✅ **Search Functionality**: Title-based path searching
- ✅ **Path Cloning**: Complete duplication with reference updates
- ✅ **Bulk Operations**: Multiple path handling
#### JSON Operations
- ✅ **Import/Export**: Round-trip data integrity
- ✅ **Validation**: Structure and content validation
- ✅ **Error Handling**: Malformed JSON recovery
#### Advanced Features
- ✅ **Statistics**: Database and path-level analytics
- ✅ **Search**: Content-based path discovery
- ✅ **Validation**: Data integrity checking
- ✅ **Concurrent Operations**: Multi-threaded safety testing
### Test Scenarios
- **Basic Workflows**: Simple path creation → retrieval → deletion
- **Complex Structures**: Multi-node paths with various exercise types
- **Error Conditions**: Non-existent resources, invalid data
- **Performance**: Concurrent operations, large datasets
- **Data Integrity**: Reference consistency, transaction safety
## 🔧 Test Configuration
### Environment Variables
```bash
# Enable debug logging during tests
export RUST_LOG=debug
# Enable backtraces for better error debugging
export RUST_BACKTRACE=1
```
### Test Database Settings
Tests use temporary SQLite databases with:
- Unique UUID-based naming to prevent conflicts
- Automatic cleanup on test completion
- Full schema migrations applied
- WAL mode for better concurrency
### Parallel Execution
Tests run in parallel by default. To run sequentially:
```bash
cargo test -- --test-threads=1
```
## 🛠️ Troubleshooting
### Common Issues
#### Database Lock Errors
```
Error: database is locked
```
**Solution**: Reduce parallel test threads or ensure proper cleanup
```bash
cargo test -- --test-threads=1
```
#### Missing Dependencies
```
Error: could not find dependency
```
**Solution**: Install development dependencies
```bash
cargo build --tests
```
#### File Permission Errors
```
Error: Permission denied
```
**Solution**: Check permissions on test directories
```bash
mkdir -p test_dbs && chmod 755 test_dbs
```
### Debug Mode
Enable detailed logging for debugging:
```bash
RUST_LOG=debug cargo test test_name -- --nocapture
```
## 📈 Performance Benchmarks

### Test Statistics
- **Total Test Functions**: 12 comprehensive test cases
- **Test Execution Time**: ~2-5 seconds for full suite
- **Code Coverage**: High coverage of repository layer
- **Reliability**: Zero flaky tests, consistent results
## 📚 Adding New Tests
### Adding a New Test Function
1. Choose the appropriate test file (`basic_tests.rs` or `simplified_repository_tests.rs`)
2. Follow the existing pattern:
```rust
#[tokio::test]
async fn test_my_new_feature() -> Result<(), Box<dyn std::error::Error>> {
let test_db = TestDb::new().await?;
let repo_manager = RepositoryManager::new(&test_db.pool);
// Your test logic here
test_db.cleanup().await?;
Ok(())
}
```
### Test Guidelines
- Always use isolated test databases
- Include both success and failure scenarios
- Test error conditions and edge cases
- Verify data integrity after operations
- Clean up resources properly
### Performance Testing
For performance-critical tests:
```rust
let start_time = std::time::Instant::now();
// Operation to test
let duration = start_time.elapsed();
println!("Operation took: {:?}", duration);
```
## 🎉 Success Metrics
The current test suite ensures:
- **Reliability**: All repository operations work correctly
- **Performance**: Operations complete within acceptable timeframes
- **Safety**: Concurrent access doesn't cause data corruption
- **Integrity**: Data relationships are properly maintained
- **Robustness**: Graceful handling of error conditions
This test infrastructure provides a solid foundation for continued development and ensures the Flalingo backend remains stable and performant.
