If you try to simulate a Event while shallowing an Element you could mock the document.addEventListener method:

let events = [];
document.addEventListener = jest.fn((event, cb) => {

});

shallow();

// trigger the keypress event
events.keyup({key: 's'});

// your test expectations
expect(someMethod).toBeCalledTimes(1);
