How does it ensure the generated data is realistic?

It uses semantic mapping to analyze field names and types, automatically choosing appropriate Faker.js methods for fields like names, emails, IDs, and addresses.

Does it support reproducible tests for CI/CD?

Yes, the skill includes a deterministic mode that uses Faker seeding to ensure the same data is generated every time your tests run.

Can I use this for complex relational data?

Yes, the skill can generate related factories and provides methods to build entities alongside their dependencies, such as an Order with a pre-generated User.

What source formats does this skill support for factory generation?

The skill supports a wide range of sources including TypeScript interfaces, Prisma schemas, JSON schemas, database migrations, and OpenAPI specifications.

보안 및 테스팅

Automatically generates realistic, type-safe test data factories from database schemas and TypeScript interfaces using Faker.js.

The Test Data Factory Generator skill streamlines the creation of robust test infrastructure by automatically mapping your models, schemas, and TypeScript types to dynamic data factories. It eliminates the need for brittle, hard-coded fixtures by leveraging Faker.js to produce realistic synthetic data that supports complex relationships, custom traits, and deterministic seeding. Whether you are working with Prisma, OpenAPI, or raw TypeScript, this skill helps reduce test setup boilerplate by up to 60%, ensuring your test suite remains maintainable as your schema evolves.
