Mock Jutsu

Mock Jutsu is an algorithmic mock data generator that produces cryptographically valid, spec-compliant test data — not random strings that break your validation logic.

Why Mock Jutsu? Most mock data tools (Faker, Mockaroo) generate plausible-looking but technically invalid data. Mock Jutsu generates data that actually passes real-world validators: Luhn-checked card numbers, ISO 9362-compliant BIC codes, Damm-verified IBANs, IMEI with correct check digits, and 390+ more types across 17 data domains.

Key Features:

• 390+ data types across Financial, Identity, Healthcare, IoT, Telecom, Security and more
• 6 locale support (TR, US, UK, DE, FR, RU) with locale-aware outputs
• Zero dependencies — pure Python core, installs in seconds
• CLI for local serverless use (mockjutsu generate cardnum --network visa --mask)
• Python library (pip install mockjutsu)
• REST API for any language/platform
• JMeter Plugin for load testing pipelines
• PCI DSS / GDPR / KVKK compliant masking built-in
• 6,100+ automated tests, 97% coverage

Use Cases:

• API testing and QA automation
• Load testing with JMeter
• Database seeding
• Demo data for presentations
• Security and compliance testing
