 # FAST-API-APP
+
+A modern, scalable, and production-ready FastAPI application designed for managing users, posts, and votes. This project demonstrates best practices in API development, testing, and deployment, making it an excellent showcase for recruiters and collaborators.
+
+---
+
+## 🚀 Features
+
+- **User Management**: Create, retrieve, and manage users with secure authentication.
+- **Post Management**: Full CRUD operations for posts with ownership validation.
+- **Voting System**: Users can upvote or remove votes on posts.
+- **Authentication**: Secure user authentication using OAuth2 and JWT tokens.
+- **Database Integration**: SQLModel and Alembic for database modeling and migrations.
+- **Testing**: Comprehensive unit and integration tests using `pytest`.
+- **Containerization**: Docker support for seamless development and production environments.
+- **CI/CD**: Automated testing and deployment pipelines using GitHub Actions and Render.
+- **API Documentation**: Interactive API documentation with Swagger UI and ReDoc.
+
+---
+
+## 🛠️ Technologies Used
+
+### Backend Framework
+
+- **FastAPI**: High-performance, modern web framework for building APIs with Python 3.12+.
+
+### Database
+
+- **PostgreSQL**: Relational database for storing application data.
+- **SQLModel**: Combines SQLAlchemy and Pydantic for database modeling.
+- **Alembic**: Database migrations.
+
+### Authentication
+
+- **OAuth2**: Secure authentication with JWT tokens.
+
+### Testing
+
+- **Pytest**: Unit and integration testing framework.
+- **HTTPX**: Asynchronous HTTP client for testing API endpoints.
+
+### Containerization
+
+- **Docker**: Containerization for development and production environments.
+- **Docker Compose**: Simplified multi-container orchestration.
+
+### CI/CD
+
+- **GitHub Actions**: Automated testing and deployment pipelines.
+- **Render**: Cloud platform for deploying the application.
+
+### API Documentation
+
+- **Swagger UI**: Interactive API documentation [[Swagger UI](https://fast-api-app-f69e.onrender.com/docs)].
+- **ReDoc**: Alternative API documentation interface [[ReDoc](https://fast-api-app-f69e.onrender.com/redoc)].

+
+## 🧪 Testing
+
+## This project includes a robust test suite to ensure the reliability of the application. Both **unit tests** and **integration tests** are implemented to validate individual components and their interactions.
+
+### Running Tests
+
+1. Install the required dependencies:
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+2. Run the test suite:
+   ```bash
+   pytest -v -s
+   ```
+
+### Test Coverage
+
+#### Unit Tests
+
+- **Users**:
+  - User creation and validation.
+  - Token generation and authentication.
+- **Posts**:
+  - CRUD operations for posts.
+  - Ownership validation.
+- **Votes**:
+  - Adding and removing votes.
+  - Duplicate vote handling.
+
+#### Integration Tests
+
+Integration tests validate the interaction between multiple components, such as database operations, authentication, and API endpoints.
+
+Example: Integration test for creating a post and voting on it:
+
+```python
+# filepath: tests/test_integration.py
+import pytest
+
+def test_create_post_and_vote(client, test_user, token_headers):
+    # Create a post
+    response = client.post(
+        "/posts/",
+        json={"title": "Integration Test Post", "content": "This is a test."},
+        headers=token_headers,
+    )
+    assert response.status_code == 201
+    post_id = response.json()["id"]
+
+    # Vote on the post
+    vote_response = client.post(
+        "/vote/",
+        json={"post_id": post_id, "dir": 1},
+        headers=token_headers,
+    )
+    assert vote_response.status_code == 201
+    assert vote_response.json()["message"] == "Vote added successfully"
+```
