.toHaveBeenCalledWith(arg1, arg2, …)

Also under the alias: .toBeCalledWith()

Use .toHaveBeenCalledWith to ensure that a mock function was called with specific arguments.

For example, let's say that you can register a beverage with a register function, and applyToAll(f) should apply the function f to all registered beverages. To make sure this works, you could write:

test('registration applies correctly to orange La Croix', () => {
  const beverage = new LaCroix('orange');
  register(beverage);
  const f = jest.fn();
  applyToAll(f);
  expect(f).toHaveBeenCalledWith(beverage);
});
