SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

AI-assisted development often suffers from repeated blind spots when the same model writes and reviews code, leading to regressions; this Skill provides a structured approach to regression testing, sandbox-mode API testing without database dependencies, and automated bug-check workflows to catch AI-induced issues early.

Core Features & Use Cases

  • Sandbox-Mode API Testing setup using Vitest and Next.js App Router.
  • A test helper library to simulate requests and parse responses.
  • Regression test patterns and templates for common AI-induced bugs.
  • Integration into a bug-check workflow to enforce automated test-first behavior.
  • Guidance for writing tests that prevent AI blind spots in production.

Quick Start

Run a sandbox-mode regression test suite against your API routes to lock in fixes and prevent AI-review regressions.

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-induced regression bugs in Next.js API routes?▼

Prevent AI-induced regression bugs by running sandbox-mode API tests using Vitest against Next.js routes. This validates responses without database dependencies and enforces test-first workflows to catch issues early.

What is sandbox-mode API testing and how does it validate AI-generated code?▼

Sandbox-mode API testing isolates endpoint execution using Vitest to simulate requests and parse responses. It validates AI-generated code by checking cross-path behavior and sandbox versus production parity without touching the database.

How do I set up regression test templates for AI-assisted development environments?▼

Set up regression test templates by integrating structured Vitest scaffolding into your bug-check workflow. This automates test-first behavior and provides patterns to target common blind spots in AI code review loops.

Can I use Vitest to test Next.js App Router endpoints without a database?▼

Yes, you can use Vitest to test Next.js App Router endpoints without a database by utilizing sandbox-mode API testing. A provided test helper library simulates requests and parses responses for isolated validation.

Why does the same AI model writing and reviewing code cause repeated regressions?▼

The same AI model writing and reviewing code causes regressions due to inherent blind spots in its logic. Automated regression-test workflows with structured templates are required to independently verify the generated outputs.

What are the limitations of using sandbox mode for regression validation?▼

Sandbox mode limitations include the requirement to maintain sandbox versus production parity. While it removes database dependencies, discrepancies between the isolated environment and production can mask environment-specific bugs.
