CI/CD & Deployment

This project uses a robust GitHub Actions workflow to build, test, and deploy the API and SQL Server to Google Kubernetes Engine (GKE) using Helm. See the workflow in .github/workflows/deploy.yml.

Key Features:

Automated Docker build and push to Google Artifact Registry
Secure secret management via GitHub Secrets and Helm
Helm-based deployment for both API and SQL Server
Waits for SQL Server readiness before deploying API
Health checks and HPA (Horizontal Pod Autoscaler) integration
Load testing and scaling verification

Challenges & Solutions:

YAML/Helm syntax: Fixed indentation, quoting, and linter issues for error-free deployment.
Secret management: Ensured all sensitive values are injected via secrets, not hardcoded.
Environment variable propagation: .NET does not expand ${VAR} in appsettings.json, so connection strings are built at runtime from env vars in Program.cs.
Pod readiness: Added /health endpoint and tuned liveness/readiness probes for reliable startup.
Password consistency: Unified secret names for DB credentials across API and SQL Server.
HPA testing: Automated load tests to verify autoscaling (see HPA Load Testing).

📋 Prerequisites

Docker Desktop
.NET 8.0 SDK (for development)
Visual Studio 2022 or VS Code (optional)

🚀 Quick Start

Clone the repository

git clone <repository-url>
cd RestaurantMenu

Start the application
```
docker-compose up --build
```
Access the API
- API: http://localhost:8080
- Swagger UI: http://localhost:8080/swagger

Environment Configuration

Before running the application, copy the example environment file and fill in your own secrets:

cp .env.example .env
# Then edit .env and set your database password, JWT secret, etc.

Never commit your .env file to version control.

The application and Docker Compose will automatically use variables from your .env file for sensitive configuration (database credentials, JWT secret, etc.).

Local Development

Install dependencies
```
dotnet restore
```
Update database connection (optional)
- Modify appsettings.json if you want to use a different SQL Server instance
Run the application
```
dotnet run
```

🧪 Testing

This project includes a comprehensive test suite that validates all core functionality of the Restaurant Menu API.

Test Isolation & Database Seeding

Each test runs in a clean, seeded database. The test infrastructure resets and reseeds the database before every test, ensuring no test state leaks between tests.
Seeding logic is shared with the main application and includes roles, admin user, and menu items.
TestBase uses xUnit's IAsyncLifetime to guarantee per-test isolation.

Running Tests

Using Docker (Recommended) ⭐

chmod +x run-tests.sh
./run-tests.sh

Tests are executed one by one in a single, persistent Docker container for speed and reliability.
The test container is kept alive for the duration of the test run, and the database is reset and reseeded before each test.
Clear pass/fail output for each test is shown in the terminal.

Manual Docker Commands

# Build the test image
docker build -f Dockerfile.tests -t restaurant-api-tests .
# Start the test database and test container (keep-alive mode)
docker compose -f docker-compose.test.yml up -d --build
# Run a specific test (example)
docker exec <test-container-id> dotnet test tests/RestaurantMenuAPI.Tests/RestaurantMenuAPI.Tests.csproj --filter "FullyQualifiedName=YourTestName"

Test Features

Comprehensive Coverage: Tests all major API components
Docker Integration: Runs in containerized environment
Per-Test Isolation: Database is reset and seeded before every test
Clear Output: Green checkmarks and detailed test results
Production Ready: Validates real-world functionality
