How to get return value from renderHook

Question

I got a custom hook which return a function

export function useMyCustomHook = (dispatch) => () => {... some things with dispatching to store };

I'm trying to use the return value like this in a jest test:

  const result = renderHook(() => useMyCustomHook(useDispatch()));
  console.log(result.current);

but result.current is undefined. So how can I actually get the return value?

According to react-hooks-testing-library renderHook returns an object with result, so to access it:

const { result } = renderHook(() => useMyCustomHook(useDispatch()));
console.log(result.current);
