Feature Description

This MR implements comprehensive automated release management and E2E testing infrastructure for the GitLab Swag Shop demo project. It transforms the project into a production-ready showcase of GitLab's CI/CD, security scanning, and release automation capabilities.

What does this feature do?

This feature adds zero-touch release automation triggered by git tags:

  • Package Registry Integration: Automatically publishes static site archives (.tar.gz,.zip) with SHA256 checksums to GitLab Generic Package Registry
  • Release Automation: Creates comprehensive GitLab Releases with auto-generated changelogs, asset links, and milestone integration
  • Container Registry: Builds and publishes versioned container images on tags
  • E2E Testing: Implements 3-tier Playwright testing strategy (smoke, full, cross-browser) with 15 browser-based tests
  • Security Scanning: Full integration of SAST, Secret Detection, Dependency Scanning, and Container Scanning
  • Quality Gates: Ensures all 94 tests pass before release creation

Why is this feature needed?

For Demo Givers:

  • Demonstrates GitLab's complete DevSecOps platform in a single git push action
  • Showcases Package Registry, Release automation, and security scanning in real-world workflow
  • Provides tangible examples of CI/CD best practices for customer presentations

For Demo Project Quality:

  • Establishes enterprise-grade CI/CD patterns suitable for customer demonstrations
  • Enables fork-and-run demo setup (colleagues can demo in <20 minutes)
  • Creates repeatable, reliable release process for demo versioning

Business Value:

  • Reduces demo preparation time from hours to minutes
  • Provides concrete examples of GitLab ROI (automation, security, compliance)
  • Demonstrates integration capabilities (Container Registry + Package Registry + Security + Testing)

Implementation Details

Architecture Changes

CI/CD Pipeline Restructure:

  • Added emoji-based stage naming: 🛠️ build, ❄️ Security, 🚂 test, ⚙️ Run, 🐍 deploy, 🛑 Stop, 📚 cleanup
  • Implemented tag-triggered workflows with proper dependency chains
  • Added pipeline inputs for optional E2E testing on merge requests
  • Configured Buildah for rootless container builds (no Docker-in-Docker)

Testing Architecture:

  • Migrated from basic unittest to comprehensive pytest suite (85 unit/integration tests)
  • Added 3-tier E2E testing strategy:
    • Smoke tests: 5 critical path tests (~30 seconds)
    • Full tests: Comprehensive application validation (~5-8 minutes)
    • Cross-browser: Matrix testing across Chromium, Firefox, WebKit
  • Configured docker-compose orchestration for E2E test isolation

Release Workflow: Git Tag → Build Container → Run Tests → Security Scan → Publish Package → Create Release ↓ Quality Gates (all tests must pass)

API Changes

No application API changes - all enhancements are CI/CD infrastructure.

GitLab API Integration Added:

  • Package Registry API for artifact publishing
  • Release API for comprehensive release creation with 7 asset types
  • Milestone API for automatic release-milestone linking

Database Changes

  • No database changes

All changes are CI/CD and testing infrastructure only.

Dependencies

New Dependencies (E2E Testing):

  • playwright==1.49.1 - Browser automation for E2E tests
  • pytest-playwright - Playwright pytest integration
  • pytest-base-url - Base URL management for tests

New CI/CD Tools:

  • release-cli (official GitLab release tool)
  • buildah (rootless container builds)
  • glab CLI integration recommendations

Existing Dependencies: No changes to core Flask application dependencies.

User Experience

User Stories

As a GitLab demo giver, I want to fork the project and create a working demo in under 20 minutes so that I can focus on customer presentation rather than setup.

As a demo audience member, I want to see a complete DevSecOps workflow triggered by a single action so that I understand GitLab's end-to-end automation capabilities.

As a solutions architect, I want reference CI/CD patterns for release automation so that I can provide customers with production-ready examples.

As a fork maintainer, I want automated versioning and package publishing so that I can track demo iterations and share artifacts with colleagues.

UI/UX Changes

  • No UI changes (application functionality unchanged)
  • New user flows (demo setup and release creation workflows)

New Demo Flows:

  1. Fork Setup: Fork → Enable registries → Wait for first pipeline → Create tag → Verify release
  2. Security Demo: Navigate to Secure → Vulnerability Report → Show 4 intentional CWEs with line-level detection
  3. Release Demo: Code → Tags → New tag → Monitor pipeline → Show Package Registry, Container Registry, and Release page

Documentation Additions:

  • RunBooks/DemoSetUp.md - 15-20 minute fork setup guide
  • README.md "GitLab Demo Features" section - customer-facing navigation paths

Testing Strategy

Test Coverage

  • Unit tests for new functionality (35 new demo vulnerability tests)
  • Integration tests for feature workflows (27 Flask integration tests)
  • End-to-end tests for user scenarios (15 Playwright tests)
  • Performance tests (if applicable) (timing validation in unit tests)
  • Security tests (if applicable) (4 intentional vulnerability tests)

Current Test Status:

  • Unit/Integration: 85/85 passing (100% pass rate)
  • E2E: 15/15 passing (smoke, full, cross-browser)
  • Total: 94 tests in CI test reports
  • Coverage: 28% overall (includes demo vulnerability routes)

Test Scenarios

Unit & Integration Tests:

  1. Product catalog validation (23 tests)

  • Tag pipeline: ~10-12 minutes (includes E2E tests + release creation)

Security Considerations

  • No security implications (demo project with intentional vulnerabilities)
  • New security measures implemented (comprehensive scanning)

Security Enhancements:

  • ✅ SAST Integration: Detects 4 intentional demo vulnerabilities (CWE-798, CWE-89, CWE-78, CWE-22)
  • ✅ Secret Detection: Identifies hardcoded credentials
  • ✅ Dependency Scanning: Monitors Python package vulnerabilities
  • ✅ Container Scanning: Scans built images for vulnerabilities
  • ✅ Quality Gates: Release creation blocked if tests fail

Intentional Vulnerabilities (Demo Purpose):

  • All vulnerabilities isolated in /demo/ routes
  • Zero changes to production shopping cart routes
  • Clear documentation and warning banners in demo templates
  • Excluded from static site generation via Flask-Frozen config

Rollout Plan

  • Full deployment (CI/CD changes apply to all forks immediately)
  • Feature flag controlled
  • Gradual rollout planned
  • Requires coordination with other teams

Deployment Strategy:

  • Changes are purely CI/CD infrastructure - no application code changes
  • Forks inherit full pipeline automatically
  • Tag-based features only activate when users create git tags
  • Backward compatible - existing branch pipelines unaffected

Rollout Timeline:

  1. ✅ Merged to this fork (October 12, 2025)
  2. ✅ Validated with multiple tag pipelines (v0.1.0-rc1, v0.1.0-rc2)
  3. 🔄 Propose to upstream (this MR)
  4. 📋 Upstream review and merge
  5. 🎉 Available to all forks via upstream sync
