Continuous integration pipelines help enable automation of tasks like testing and code checks. Hence, when you implement CI pipelines in Laravel projects, your code gets automatically tested for each update or change. Today we will discuss what CI pipelines are in Laravel, why you should care and how to integrate the two together. 

Continuous Integration (CI) in Laravel

Continuous Integration is the process of setting up automatic testing and validation for ensuring app safety against voluntary or involuntary changes. This is how you achieve it: 

  • Running PHP code style checks
  • Executing unit and feature tests
  • Running Laravel Dusk for browser testing (optional)
  • Building and deploying if tests pass

Why CI Matters for Laravel Projects

  • Catch bugs and breaking changes early
  • Ensure consistent code formatting with linters
  • Speed up team collaboration and PR approvals
  • Automate deployment to staging/production environments
  • Reduce human error during releases

How to Set Up a CI Pipeline for Laravel (Step-by-Step)

Let’s walk through a real-world example using GitHub Actions, Laravel 10+, and PHPUnit tests.

Step 1: Create .github/workflows/ci.yml File

Inside your Laravel project, create the GitHub Actions workflow file:

Bash:

mkdir -p .github/workflows
touch .github/workflows/ci.yml

Step 2: Configure the CI Pipeline

Here’s a complete example CI configuration for a Laravel project using GitHub Actions:

yaml

name: Laravel CI
on: push: branches: [main] pull_request: branches: [main]
jobs: laravel-tests: runs-on: ubuntu-latest services: mysql: image: mysql:8.0 env: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: laravel ports: - 3306:3306 options: --health-cmd="mysqladmin ping --silent" --health-interval=10s --health-timeout=5s --health-retries=3 steps: - name: Checkout code uses: actions/checkout@v3 - name: Set up PHP uses: shivammathur/setup-php@v2 with: php-version: '8.2' extensions: mbstring, bcmath, pdo_mysql tools: composer, php-cs-fixer - name: Copy .env run: cp .env.example .env - name: Install dependencies run: composer install --prefer-dist --no-progress --no-suggest - name: Generate key run: php artisan key:generate - name: Wait for MySQL to be ready run: | sleep 10 php artisan migrate --force - name: Run PHPStan (Static Analysis) run: vendor/bin/phpstan analyse - name: Run PHPUnit tests run: vendor/bin/phpunit

What This Pipeline Does:

StepPurpose
actions/checkoutClones your repo
setup-phpInstalls PHP 8.2 with required extensions
composer installInstalls Laravel dependencies
php artisan key:generateSets up Laravel app key
php artisan migrateApplies database migrations
phpstanRuns static analysis
phpunitRuns all tests in tests/Feature and tests/Unit

Optional: Add Code Style Checkers

To enforce PSR-12 or Laravel Pint standards, add:

Bash:

- name: Run Pint (Laravel code style fixer) run: vendor/bin/pint --test

Step 3: Add Deployment (Optional)

You can add deployment to services like Forge, Envoyer, or a VPS:

Bash:

- name: Deploy to Production if: github.ref == 'refs/heads/main' && github.event_name == 'push' run: curl -X POST ${{ secrets.DEPLOY_WEBHOOK_URL }}

Or use tools like Laravel Forge’s Deploy API.

Step 4: Set Secrets for CI

In your GitHub repository, go to: Settings → Secrets → Actions
Add keys like:

  • DEPLOY_WEBHOOK_URL
  • DB_PASSWORD
  • APP_ENV
  • APP_KEY

Use them securely in your pipeline:

env: DB_PASSWORD: ${{ secrets.DB_PASSWORD }}

Step 5: Speed Up Builds with Caching

Add this to cache Composer dependencies:

yaml:

- name: Cache Composer dependencies uses: actions/cache@v3 with: path: vendor key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.lock') }} restore-keys: ${{ runner.os }}-composer-

Best Practices for Laravel CI Pipelines

TipBenefit
Use .env.testing for test configsKeeps test settings separate
Run static analysis toolsDetect issues before runtime
Cache Composer + Node modulesFaster builds
Separate jobs for testing, buildingImprove readability and modularity
Fail fast on test errorsStop deployment early when something breaks

CI Tools Compatible with Laravel

ToolDescription
GitHub ActionsFree for public repos, tightly integrated with GitHub
GitLab CI/CDPowerful for private projects with Docker support
Bitbucket PipelinesGreat for Atlassian teams
CircleCIHighly customizable, Docker-native
JenkinsSelf-hosted, enterprise-grade CI

Final Thoughts

A CI pipeline is no longer optional,  it’s a must-have for modern Laravel projects. From enforcing code quality to automating deployment, setting up a CI/CD workflow with help of skilled Laravel developers can improve the reliability, speed, and confidence of your entire development lifecycle.

By using tools like GitHub Actions, PHPUnit, PHPStan, and Laravel Pint, you can automate every push, pull request, and deployment with minimal effort.
