Testing · Middle · Question 23 of 75

What does `renderHook` return?

const { result } = renderHook(() => useCounter());
act(() => result.current.increment());
expect(result.current.count).toBe(1);

✓Correct answer: An object whose result.current holds the hook's latest return value
2The hook's initial value only
3A mock of the hook

Explanation

Updates from outside React events must be wrapped in act. For hooks used by one component, testing that component is often better.
