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.

Any dependencies the base factory declares are forwarded to it, so a variant of a factory with dependencies is made in the same way as any other variant.

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 }
