Also under the alias: .toReturnWith(value)

Use .toHaveReturnedWith to ensure that a mock function returned a specific value.

For example, let’s say you have a mock drink that returns the name of the beverage that was consumed. You can write:

test('drink returns La Croix', () => {
  const beverage = {name: 'La Croix'};
  const drink = jest.fn(beverage => beverage.name);

  drink(beverage);

  expect(drink).toHaveReturnedWith('La Croix');
});
