Mock dependency in jest with typescript

Question

When testing a module that has a dependency in a different file. When assigning that module to be jest.Mock typescript gives an error that the method mock

Answer 1

I use the pattern from @types/jest/index.d.ts just above the type def for Mocked (line 515):

import { Api } from "../api";
jest.mock("../api");

const myApi: jest.Mocked = new Api() as any;
myApi.myApiMethod.mockImplementation(() => "test");
