CI/CD Fundamentals

CI/CD Fundamentals cover the pipelines that automate code integration, testing, and deployment.

Why it is useful: Automation reduces human error, speeds up feedback loops, and enables frequent releases.

Example (GitHub Actions workflow):

name: CI

on:
  push:
    branches: [ main ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Set up Node
        uses: actions/setup-node@v3
        with:
          node-version: '18'
      - run: npm install
      - run: npm test

This workflow checks out code, installs Node, runs npm install, and executes tests on every push to main. If any step fails, the pipeline stops and reports the failure before anything reaches production.

Best Practices

• Run tests automatically on every pull request so broken code never merges unnoticed.
• Keep builds fast — slow pipelines get skipped by developers.
