name: kith-test-factory description: Specialized in generating complex, realistic mock family datasets and unit tests for Kith. Use when updating mocks/familyData.ts, testing new tree traversal logic, or creating edge-case scenarios (blended families, orphans, many generations).

Kith Test Factory

This skill automates the creation of high-fidelity test data and unit tests for the Kith genealogy engine.

Core Workflows

1. Mock Data Generation

When asked to create test data:

•Relational Integrity: Ensure that if Person A is Person B's parent, Person B must have Person A in their parents array.
•Diversity: Generate varied names, dates, and locations.
•Scenario Matching: Use test-scenarios.md to select a predefined family structure (e.g., "Blended Family").

2. Component/Service Testing

When writing tests in __tests__/ or services/:

•Vitest: Use Vitest patterns (describe/it/expect).
•Mock Services: Mock FamilyService or ActivityService when testing UI components to ensure fast, isolated tests.
•Snapshot Testing: Use for tree visualizations to detect layout regressions.

Guidelines

•Scalability: Don't just generate one member; generate the whole connected tree.
•Realism: Use logical dates (parents must be older than children).
•Standardization: Always adhere to the FamilyMember type in types/family.ts.
