我想斷言當一個禁用的按鈕被點擊時，它的onClick事件不會被觸發(fā)。我如何用酶來做到這一點？請參閱下面的示例代碼。謝謝！示例按鈕.jsx：import React from 'react';const SampleButton = () => (  <button    disabled={true}    onClick={() => console.log('You clicked me!')}    test-attr="button"    type="button"  >    Click Me  </button>);export default SampleButton;sampleButton.test.jsx：import React from 'react';import { shallow } from 'enzyme';import SampleButton from './sampleButton';test('cannot click button if disabled', () => {  const wrapper = shallow(<SampleButton />);  const button = wrapper.find('[test-attr="button"]');  button.simulate('click');  // assert that `onClick` has not been fired});
