# **CI/CD with GitHub Actions**  

This guide explains how to automate testing, linting, and deployment for the Py Launch Blueprint project using GitHub Actions. [Learn more](../tools/github_actions.md).  

## **Workflow Overview**  

The CI/CD workflow (`.github/workflows/ci.yaml`) runs on:  
- Pushes to `main`  
- Pull requests targeting `main`  

### **Jobs**  
- **Test**: Runs tests on Python 3.10 and 3.11  
  - Sets up environment using `uv` and `actions/setup-python`  
  - Installs dependencies: `uv sync --all-extras --dev`  
  - Runs MyPy (`uvx mypy`), Ruff (`uvx ruff check`), and pytest (`uvx pytest`)  

## **Workflow Configuration**  

```yaml
name: CI/CD

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.10", "3.11"]

    steps:
      - uses: actions/checkout@v4
      - uses: astral-sh/setup-uv@v5
      - uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}
      - run: uv sync --all-extras --dev
      - run: uvx mypy py_launch_blueprint/
      - run: uvx ruff check py_launch_blueprint/
      - run: uvx pytest
```

## **Customization**  

- **Add more Python versions**:  
  ```yaml
  strategy:
    matrix:
      python-version: ["3.10", "3.11", "3.12"]
  ```  
- **Add security scanning**:  
  ```yaml
  - name: Run security scan
    run: uvx bandit -r py_launch_blueprint/
  ```  
- **Cache dependencies**:  
  ```yaml
  - uses: actions/cache@v3
    with:
      path: .venv
      key: venv-${{ runner.os }}-${{ hashFiles('**/pyproject.toml') }}
  ```
