创建快照时,Jest/Enzyme ShallowWrapper为空 [英] Jest/Enzyme ShallowWrapper is empty when creating Snapshot
问题描述
所以我正在为我的Item组件编写一个测试,我尝试呈现ItemCard
组件,然后使用该包装器创建快照,但是它返回一个空的ShallowWrapper {}
So I'm writing a test for my Item component and I tried to render the ItemCard
component and then use that wrapper to create a snapshot but it returns an empty ShallowWrapper {}
请参阅代码以获取更多信息:
Please see the code for more info:
Item.test.js
Item.test.js
import { shallow } from 'enzyme';
import { ItemCard } from '../Item';
const fakeItem = {
id: 'aksnfj23',
title: 'Fake Coat',
price: '40000',
description: 'This is suuuper fake...',
image: 'fakecoat.jpg',
largeImage: 'largefakecoat.jpg',
};
describe('<ItemCard/>', () => {
it('renders and matches the snapshot', () => {
const wrapper = shallow(<ItemCard me item={fakeItem} showButtons />);
// console.log(wrapper.debug());
expect(wrapper).toMatchSnapshot();
});
});
它创建的快照:
// Jest Snapshot v1
exports[`<ItemCard/> renders and matches the snapshot 1`] = `ShallowWrapper {}`;
据我所知ShallowWrapper应该包含一些内容而不是空的.
As far as I know the ShallowWrapper should have some content in it instead of being empty..
有人可以告诉我我在做什么错吗?
Can someone tell me what am I doing wrong here?
谢谢
