## Prerequisites

* **Go:** Version 1.22 higher
* **PostgreSQL:** Local 
* **OS:** Windows / Linux / macOS

## Environment Variables

The application relies on the following environment variables for database configuration and testing:

| Variable | Description | Default / Example |
| :--- | :--- | :--- |
| `DB_HOST` | Database host address | `localhost` |
| `DB_PORT` | Database port | `5432` |
| `DB_USER` | Database username | `postgres` |
| `DB_PASSWORD` | Database password | *Your local database password from postgresql* |
| `DB_NAME` | Database name (**must end with `_test`** during testing) | `w04_5803025020` |

---

## Database Setup

Before running integration tests, create a PostgreSQL test database with a name ending in `_test` as a safety guard[cite: 3, 4]:

```sql
CREATE DATABASE w04_5803025020;
