SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a rigorous, constitutional framework for testing frontend code, ensuring that Kimen components are reliable, accessible, and maintainable without the pitfalls of traditional coverage-focused testing.

Core Features & Use Cases

  • Constitutional QA: Implements a strict testing discipline including TDD, mutation testing, and S-ID traceability for Kimen components.
  • Generative UI Validation: Provides specialized guardrails and schema-first testing strategies for LLM-generated UI output.
  • Use Case: When developing a new ki-button component, use this Skill to define behavior contracts, ensure accessibility compliance, and set up automated quality gates that prevent regressions.

Quick Start

Use the frontend-qa skill to audit the current test suite for the ki-button component and verify it meets the constitutional requirements for accessibility and regression coverage.

FAQPage Schema
How do I enforce TDD and accessibility standards for web components?

Mutation testing verifies web component test integrity by systematically mutating code to detect uncaught behavioral changes, ensuring your test suite effectively prevents regressions rather than just achieving high surface-level coverage metrics.

What's the best way to test generative UI output from LLMs?

Schema-based guardrails validate generative UI output by enforcing strict structural contracts on LLM-driven interfaces, preventing malformed renders and ensuring the generated components conform to expected accessibility and behavioral standards.

How do I set up automated CI gates for frontend component testing?

Automated CI gates for frontend component testing are established by defining strict behavior contracts and integrating traceability checks, ensuring components meet constitutional requirements before deployment and blocking regressions automatically.

Does behavior-driven development work for generative UI validation?

Behavior-driven development works for generative UI validation by defining explicit behavior contracts that LLM-driven interfaces must satisfy, ensuring reliable and maintainable outputs through strict adherence to expected component interactions.

Why does traditional test coverage fail for web components?

Traditional test coverage fails for web components because it focuses on metric accumulation rather than behavioral integrity, missing edge cases that mutation testing and strict behavior-driven development catch effectively.
