Which ORMs are supported for schema migration?

The skill currently supports Drizzle (PostgreSQL, MySQL, and SQLite dialects), Prisma models, and TypeORM entity definitions.

Can I use the generated classes for unit testing?

Yes, the generated classes include GetAll() and GetById() methods, making them perfect for seeding mock repositories and unit testing service logic.

Is the generated data reproducible?

Yes, the skill uses consistent GUID generation and fixed mapping patterns to ensure that re-running the generator produces stable results.

How does it handle complex database relationships?

It analyzes the entity dependency graph to generate data in a specific order (root entities first, then children), ensuring all foreign keys are valid and reference existing parent objects.

Does this skill generate Entity Framework Core configurations?

No, this skill is specifically focused on generating static MockData classes and C# entity models for testing and bootstrapping, not database provider configurations.

Automatically generates realistic C# mock data classes from Drizzle, Prisma, and TypeORM schemas.

소개

The ln-723-mockdata-migrator is a specialized L3 worker skill designed to bridge the gap between database schema definitions and .NET application development. It parses existing ORM schemas to generate production-ready C# static MockData classes, complete with intelligent type mapping, PascalCase naming transformations, and realistic sample data. By ensuring relationship integrity through parent-first generation and valid foreign key cross-referencing, this skill significantly accelerates the project bootstrapping process and provides a robust foundation for unit and integration testing.

주요 기능

Built-in Accessors: Generates helper methods like GetAll(), GetById(), and relationship-based filters.
Realistic Data Generation: Uses domain-appropriate sample values instead of generic random strings for better testing context.
Intelligent Type Mapping: Automatically converts database types to C# equivalents including nullability and GUID handling.
38 GitHub stars
Relationship Validation: Ensures all foreign key relationships point to existing parent IDs within the generated data set.
Multi-ORM Parsing: Supports Drizzle (pg/mysql/sqlite), Prisma, and TypeORM schema formats.

사용 사례

Synchronizing C# data models with Drizzle or Prisma schemas in full-stack TypeScript/C# environments.
Bootstrapping .NET backend prototypes with realistic initial datasets based on existing frontend schemas.
Generating type-safe mock repositories for unit and integration testing in C# projects.
