我有一个超级简单的测试，只是拒绝查看我传递的值：

测试：
const shallow = (props = {}) => shallow(<ParagraphComponent {...props} />);测试失败，并显示：
预期的模拟函数已被调用： {“单位”：“ px”，“值”：123} 作为参数2，但它被称为 {“ unit”：“”，“ value”：“”}。
到底该如何调用该函数，但是即使我传递的是实际值，也使用空值？！
我尝试传递it('Should fire onChange', () => {
const props = {
context: context.paragraphStyle.style,
onChange: jest.fn()
};
const instance = shallow(props);
const paragraphInput = instance.find('paragraphInput.fontsize');
paragraphInput.prop('onChange')(undefined, { unit: "px" value: '123' });
paragraphInput.prop('onBlur')(); // required to fire the onChange
expect(props.onChange).toBeCalledWith('font.size', { unit: 'px', value: 123 });
});
，尝试使用{ target: { value: 123 }}，我尝试将值传递到act()，但是没有用。
