This Skill automates end-to-end and security testing for Vercel Preview Deployments, ensuring rapid validation of new changes before merge.

Core Features & Use Cases

  • Smoke Tests: Validate critical flows (login, upload, analysis)
  • Visual Regression: Baseline screenshots across devices with tolerance checks
  • Security Tests: OWASP-based checks for potential vulnerabilities
  • GDPR Region Check: Verifies data residency in fra1 region
  • CI/CD Integration: Pre-deploy gates and PR-based checks

Quick Start

Run the full suite with the standard command to execute all tests, or target specific subsets as needed:

  • /preview-test
  • /preview-test --security

FAQPage Schema
How do I automate end-to-end testing for Vercel preview deployments?▼

This skill automates end-to-end testing for Vercel preview deployments by executing Playwright tests via PR validations or manual commands. It runs smoke, visual, security, and GDPR checks to validate changes before merge.

Can I run only security and OWASP checks on a Vercel preview?▼

Yes, you can run targeted security checks on a Vercel preview by invoking the specific test subset command. This executes OWASP-based vulnerability validations without running the full test suite.

Do I need Playwright and npm installed to run preview tests?▼

Yes, Playwright and npm tooling are required dependencies to run the automated tests. The solution leverages these tools to execute end-to-end validations and visual regressions across your preview environments.

What's the best way to integrate PR-based pre-deploy gates with Vercel previews?▼

The best way to integrate pre-deploy gates is using CI/CD workflows that trigger automated validations on Vercel previews. This ensures critical flows, visual baselines, and security checks pass before allowing a merge.

How does GDPR region checking work for Vercel preview deployments?▼

GDPR region checking verifies data residency for the fra1 region during your preview deployment tests. This automated check ensures your application complies with data residency requirements before changes are merged.
