SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually writing thorough test suites for UI components is time-consuming and requires deep knowledge of testing patterns, often leading to incomplete coverage or delayed releases. This Skill automates the generation of comprehensive test files, ensuring robust quality assurance.

Core Features & Use Cases

  • Full Test Suite Generation: Creates test files with all required categories: rendering, variants, colors, sizes, ref forwarding, className merging, HTML attributes, accessibility, and ColorContext integration.
  • Accessibility Testing: Integrates vitest-axe checks to ensure components meet accessibility standards from the start, reducing compliance risks.
  • Pattern-Driven Testing: Follows established base-joy testing patterns, including it.each for variants/colors/sizes and specific checks for ColorContext behavior.
  • Use Case: When a new Sheet component is developed, use this Skill to instantly generate its test suite, covering all critical aspects from rendering to accessibility and context integration.

Quick Start

Generate a test suite for the Sheet component, including accessibility checks and ColorContext integration tests.

Frequently Asked Questions about test-generator

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

FAQPage Schema
How do I generate comprehensive test suites for UI components?▼

Generate comprehensive test suites by automating creation of test files that validate rendering, variants, colors, sizes, accessibility, and state changes. The Skill produces ready-to-run tests following Testing Library principles and bans CSS class assertions, covering critical component behavior end-to-end.

What does accessibility testing in component test suites involve?▼

Accessibility testing integrates vitest-axe checks to validate that UI components meet accessibility standards automatically. This approach reduces compliance risks by embedding accessibility validation into the test generation process from the start.

Can I generate tests that avoid CSS class and styling implementation details?▼

Yes. The test generation follows Testing Library principles explicitly, banning CSS class assertions and focusing on user-facing interactions and behavior. Tests validate component functionality without coupling to styling implementation.

Does this work with component libraries that use ColorContext?▼

Yes. The Skill generates tests that include ColorContext integration checks alongside rendering, variants, and attribute validation. It follows base-joy testing patterns and produces tests ready to run immediately.

How do I test multiple component variants, colors, and sizes efficiently?▼

The Skill uses pattern-driven testing with it.each to generate parameterized tests across all variants, colors, and sizes automatically. This eliminates manual test duplication while ensuring consistent coverage across component configurations.
