generate-jest-mocks

Automatically generate Jest mocks for your Javascript/Typescript files based on module usage.

Features

Consider the following file named create_user.js:

const api = require("api");
const track = require("track");
const { flush } = require("cache");

function main(user) {
  const userID = api.users.create(user);
  track("create_user", userID);
  flush(userID);
}

Running Generate Jest Mocks from the test file create_user.test.js will result in the following manual Jest mocks being generated:

jest.mock('api', () => ({
  users: {
    create: jest.fn(),
  }
});
jest.mock('track', () => jest.fn());
jest.mock('cache', () => ({ flush: jest.fn() }));

Or alternatively, when running Generate Jest Auto Mocks, Jest automocks can be generated:

jest.mock("api");
jest.mock("track");
jest.mock("cache");

It also handles ES6 and Typescript files. For:

import cache, {set} from 'cache';

set('foo', 'bar');
cache.flush();
}

the following will be generated:

jest.mock("cache", () => ({
  default: {
    flush: jest.fn(),
  },
  set: jest.fn(),
}));
