Mocking bcrypt library with Jest and TypeScript

jest-mock-bcrypt-example.ts

// Using compare method as example

const bcryptCompare = jest.fn().mockRejectedValue(new Error('Random error'));
(bcrypt.compare as jest.Mock) = bcryptCompare;
//call method that uses bcrypt.compare with async

const bcryptCompare = jest.fn().mockResolvedValue(true);
(bcrypt.compare as jest.Mock) = bcryptCompare;
//call method that uses bcrypt.compare with async

Thank you!
