SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

AI-assisted development often suffers from regression when the same model writes and reviews code, allowing bugs to re-emerge. This Skill provides automated regression testing workflows to detect and prevent those blind spots early.

Core Features & Use Cases

  • Sandbox-mode API testing with deterministic, mockable environments (Vitest + Next.js) to exercise edge cases without a real database.
  • Regression test generation after bug fixes to lock in protections against reoccurrence.
  • Bug-check workflows that combine unit tests, integration checks, and AI-assisted reviews to maintain code quality across paths (sandbox vs production).
  • Guidance for constructing and maintaining coverage patterns like sandbox/production parity, SELECT clause completeness, and safe rollback.

Quick Start

Run the bug-check workflow to automatically generate and execute regression tests in your sandbox environment before applying changes.

Frequently Asked Questions about ai-regression-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent AI coding blind spots from causing regressions in Next.js?▼

AI regression testing prevents coding blind spots by applying automated workflows that catch bugs missed during AI-assisted reviews. It uses deterministic tests to enforce sandbox and production parity, ensuring errors are detected before code changes are applied.

How do I generate regression tests after a bug fix in Vitest?▼

Regression test generation locks in protections against bug reoccurrence by automatically creating and executing tests in your sandbox environment. You can run the bug-check workflow to validate fixes before applying changes to the codebase.

Can I test API edge cases in Next.js without connecting to a real database?▼

Sandbox-mode API testing allows you to exercise edge cases without a real database by using deterministic, mockable environments with Vitest and Next.js. This isolates test execution and ensures reliable validation across sandbox and production paths.

What testing patterns should I use for sandbox and production parity?▼

Sandbox and production parity requires explicit regression-pattern coverage, including SELECT path validation and rollback scenarios. Constructing these patterns ensures your mockable sandbox environment accurately reflects production behavior during tests.

Do I need specific environment controls to run AI regression tests?▼

AI regression testing requires a Vitest and Next.js setup with explicit environment controls to enforce sandbox mode. These controls are necessary to maintain deterministic test execution and validate coverage patterns across different environments.
