I've been a QA Manager for 12 years in fintech & banking. Every project, the same problem: generating realistic test data that actually passes validation — IBAN checksums, national IDs, card numbers, MRZ codes. Existing tools like Faker give you random strings. They look valid but fail real validation rules. That means broken tests, wasted debugging hours, and production surprises. So I built Mock Jutsu — an algorithmic mock data engine that generates mathematically correct data. Not random strings, real checksums. 390+ types, 6 locales, zero external dependencies. Works as CLI, REST API, Python package, and JMeter plugin. 5955 tests passed. MIT licensed. Free forever. Would love your feedback!
