我正试图找出用jest测试MaterialUI的SelectField组件的正确方法。我需要用某些参数模拟变化。我现在所拥有的：

it('when SelectField with id city_id changed, onFilterChanged prop should be called', () => {
  const SelectField = form.findWhere(n => n.props().id === 'city_id' && n.name() === 'SelectField').find('[type="button"]')
  const spy = jest.spyOn(defaultProps, 'onFilterChanged')

  SelectField.simulate('change')

  expect(spy).toBeCalled()
})

它应该在SelectField中找到一个按钮并单击它。我的问题是如何用某些参数模拟SelectField上的更改
