VariantFactory

Creates complete items from another factory with preset overrides.

Use this factory to describe a named variation of a base factory without duplicating all the base defaults. The preset overrides are applied first, then any overrides passed to make can further customize the final item.

Usage

interface User {
  name: string;
  role: "user" | "admin";
  active: boolean;
}

const userFactory = new StaticFactory<User>({
  name: "Test User",
  role: "user",
  active: true,
});

const adminFactory = new VariantFactory<User>(userFactory, {
  role: "admin",
});

const admin = adminFactory.make();
// { name: "Test User", role: "admin", active: true }

const inactiveAdmin = adminFactory.make({ active: false });
// { name: "Test User", role: "admin", active: false }
