3 - Tests et CI/CD

• Comprendre la différence entre tests unitaires et tests d'intégration
• Écrire des tests simples et efficaces avec les bonnes pratiques
• Gérer les profils Spring (dev/test/prod)
• Mettre en place une pipeline CI complète avec GitHub Actions
• Mesurer la couverture de code

La création de profiles permet de gérer des configurations différentes, et des fichiers de configuration spécifiques à chaque profile.

Ajouter la section profiles suivante au fichier pom.xml

        <profile>

## Description
API REST pour un système e-commerce avec Spring Boot 3.

## Badges de statut
- **Build** : Statut de la compilation
- **Tests** : Résultat des tests automatisés
- **Coverage** : Pourcentage de code couvert par les tests

## Commandes

```bash
# Tests unitaires uniquement
mvn test

# Tests d'intégration uniquement
mvn verify -DskipUnitTests

# Tous les tests
mvn verify

# Rapport de couverture
mvn test jacoco:report
```

# ========== Développement local ==========

# Lancer l'app en mode dev
mvn spring-boot:run -Dspring-boot.run.profiles=dev

# Lancer l'app en mode test
mvn spring-boot:run -Dspring-boot.run.profiles=test

mvn spring-boot:run -P test


# ========== Tests ==========

# Tests unitaires uniquement (rapides, < 10s)
mvn clean test

# Tests d'intégration uniquement
mvn clean verify -DskipUnitTests

# Tous les tests
mvn clean verify

# Tests avec rapport de couverture
mvn clean test jacoco:report


# ========== Couverture de code ==========

# Générer le rapport JaCoCo
mvn jacoco:report

# Ouvrir le rapport
open target/site/jacoco/index.html

# Vérifier le seuil de couverture
mvn jacoco:check


# ========== Build ==========

# Compiler sans tests
mvn clean package -DskipTests

# Build complet
mvn clean install
