SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the creation of unit tests to maximize coverage, reduce manual effort, and ensure critical paths are exercised across React components, utilities, hooks, and API routes.

Core Features & Use Cases

Code Analysis: Inspect source files to identify testable functions, components, hooks, and classes.
Test Case Coverage: Generate happy path, edge cases, error handling, and full branch coverage.
Framework Compatibility: Produce tests compatible with Jest or Vitest, including mocks and accessibility checks.
Quality uplift: Provide guidance on improving test coverage and structure.

Quick Start

Generate tests for a given file, e.g. 'src/components/Button/Button.tsx' using Jest.

FAQPage Schema

How do I generate unit tests with 100% code coverage?▼

Unit test generation analyzes your source code to create comprehensive tests covering happy paths, edge cases, error handling, and all conditional branches. It produces Jest or Vitest tests that achieve full coverage by identifying all exports and logic paths, then writing organized test suites with mocks and accessibility checks.

Can I generate tests for React components and custom hooks?▼

Yes. Test generation handles React components (.tsx/.jsx), custom hooks (use*.ts, use*.tsx), utility functions, API routes, and other modules. Tests use React Testing Library for components and follow standard patterns compatible with Jest or Vitest.

What does the test generation process cover?▼

Test generation covers happy-path scenarios, edge cases, error handling, and all conditional branches. It analyzes source files to identify testable exports, maps logic paths, mocks external dependencies, and writes descriptive test cases organized in describe blocks following Pandora coding standards.

Do I need existing tests to use test generation?▼

No. Test generation creates tests from scratch by inspecting your source code. It requires the source file you want tested but no pre-existing test suite. The Skill analyzes exports and logic to build comprehensive coverage independently.

Does test generation work with both Jest and Vitest?▼

Yes. Test generation produces tests compatible with both Jest and Vitest. You specify your preferred test runner, and generated tests follow the appropriate syntax and patterns for that framework.

What happens with external dependencies and third-party libraries?▼

Test generation automatically mocks external dependencies during test creation. This ensures tests run in isolation and verify your code's behavior without relying on external services or libraries, enabling reliable and fast unit test execution.
