'высота' не определена с библиотекой реагировать-тест-рендеринг

Question

В моем текущем компоненте есть компоненты Collapse и RadioGroup. in опора Collapse компонента, связанного с состоянием. Когда я хочу изменить значение RadioGroup с помощью onChange prop, я получаю сообщение об ошибке. Поскольку in prop компонента Collapse равен true, и должен появиться компонент Collapse.

Эта ошибка появляется в тестовом режиме с react-test-renderer

Некоторые строки моего компонента:

. . .
const [discountType, setDiscountType] = useState('total')
. . .
const handleChange = event => {
  setDiscountType(event.target.value)
}
. . .
  <RadioGroup value={discountType} onChange={handleChange}>
. . .
  <Collapse in={discountType === 'separate'}>
      . . .
  </Collapse>
. . .

Тестовый файл:

const component = create(<MyComponent />)
const instance = component.root

it('MyComponent snapshot', () => {
  const tree = component.toJSON()
  expect(tree).toMatchSnapshot()
})

it('MyComponent handleChange correctly', () => {
  const value = 'separate'
  act(() => {
    instance.findByType(RadioGroup).props.onChange({ target: { value } }) // This line produces Error
    component.update(<MyComponent />)
  }
})

Как видите, ошибка возникает после вызова handleChange функции со значением seperate.

TypeError: Cannot set property 'height' of undefined
