I import noop from lodash:

I set a function passed to onClick as that noop in defaultProps:

//Component.jsx
import { noop } from 'lodash';

const Component = ({onClickHandler}) => {
   return <Button onClick={onClickHandler}>Click me</Button>
}

Component.defaultProps = { onClickHandler: noop }

How to test in RTL that render() gives us on onClickHandler which is noop? I already tried:

const noopSpy = jest.spyOn(require('lodash'), 'noop');
...
expect(noopSpy).toHaveBeenCalled()
expect(props.onClickHandler).toBe(noop)
