Using jest.mock('package-name') makes all exported functions mocks, which I don't want. I tried spreading the named exports back into the mock object... import * as utils from './utilities.js'; jest.mock(utils, () => ({ ...utils speak: jest.fn(), })); but got this error: The module factory of jest.mock() is not allowed to reference any out-of-scope variables. 回答1: The
