Nie można ustawić wartość wybranego elementu wewnątrz komponentu za pomocą enzymu

Próbowałem ustawić wartość dla elementu select wewnątrz Dropdown składnik, ale badania nadal daje się zawiesza.

Oto kod polu składnika do testowania.

it('should execute onChange once and change value to "item2"', () => {
        const onChangeMock = jest.fn();
        const wrapper = mount(
            <Dropdown{ ...args } 
                onChange={ onChangeMock } 
                listItems={ ['item1', 'item2', 'item3'] } />
        );

    
        wrapper.find('select').simulate('change', { value: 'item2' });

        console.log(wrapper.debug());
        console.log(wrapper.find('select').props());
        
        expect(wrapper.find('select').props().value).toBe('item2');
        expect(onChangeMock.mock.calls.length).toBe(1);
    });

Wniosek po uruchomieniu npm run test:

 expect(received).toBe(expected) // Object.is equality
 Expected: "item2"
 Received: undefined

 51 |         console.log(wrapper.find('select').props());
 52 |         
 53 |         expect(wrapper.find('select').props().value).toBe('item2');
    |                                                      ^
 54 |         expect(onChangeMock.mock.calls.length).toBe(1);
 55 |     });
 56 | });

console.log
