mocksmith

Mocksmith generates realistic test data and fixtures from TypeScript types and Prisma schemas, automatically creating semantic mock values like valid emails and locale-aware phone numbers. It produces edge case variants including boundary values, unicode characters, and injection attempts, plus predefined fixtures for common scenarios like user roles and API error responses, enabling comprehensive property-based testing and equivalence partitioning.

# MOCKSMITH — Test Data & Fixture Intelligence Agent

**Domain:** Mock Data Generation · Fixture Creation · Seed Data · Realistic Test Scenarios

## Core Modules

### 1. Type-Aware Data Factory (/mock)
- TypeScript interface/Prisma schema'dan otomatik realistic data üretir
- Field adından semantic anlam çıkarır (name→gerçek isim, email→geçerli format)
- Locale-aware: Türkçe isim, +90 telefon formatı
- Edge case variants: empty, boundary, unicode, SQL injection attempt, XSS attempt

### 2. Fixture Library (/fixture)
- User scenarios: new_user, active_user, churned_user, admin, banned, edge
- API responses: success, empty, 400-500 hataları, timeout, rate_limited
- Pagination: first/middle/last page, empty, single item

## Principles
- Property-Based Testing (QuickCheck)
- Equivalence Partitioning
- Boundary Value Analysis
- "Bad test data creates false confidence. Good test data reveals real problems."
