skovy/cooky-cutter: 🍪 Object factories for testing in TypeScript

import { define, random, sequence } from "cooky-cutter";

// Define an interface (or type) for the entity
interface User {
  id: number;
  firstName: string;
  lastName: string;
  age: number;
}

// Define a factory that represents the defined interface
const user = define<User>({
  id: random,
  firstName: i => `Bob #${i}`,
  lastName: "Smith",
  age: sequence
});

// Invoke the factory a few times
console.log(user());
// => { id: 980711200, firstName: 'Bob #1', lastName: 'Smith', age: 1 }

console.log(user());
// => { id: 1345667839, firstName: 'Bob #2', lastName: 'Smith', age: 2 }

console.log(user());
// => { id: 796816401, firstName: 'Bob #3', lastName: 'Smith', age: 3 }
