如何安装redux-antd-jest组件

Question

import React from 'react';
import { Breadcrumb as AntBreadcrumb, Breadcrumb } from 'antd';
import './breadcrumb.scss';
import { Link, withRouter, RouteComponentProps } from 'react-router-dom';
import { updateBreadcrumb } from './../../../redux/actions/baseLayout';
import { connect } from 'react-redux';
import { HomeOutlined, RightOutlined } from '@ant-design/icons';
interface NewProps {
breadcrumb: any;
}
type Props = NewProps & RouteComponentProps<{}>;
// @TODO
class Render extends React.Component<Props> {
state = {
routes: [{ path: '', breadcrumbName: '' }]
};
// eslint-disable-next-line react/no-deprecated
componentWillReceiveProps(nextProps: any) {
this.setState({
routes: this.props.breadcrumb
});
}
componentDidMount = () => {
this.setState({
routes: this.props.breadcrumb
});
};
itemRender = (route: any, params: any, routes: any, paths: any) => {
const last = routes.indexOf(route) === routes.length - 1;
return last ? (
<span>{route.breadcrumbName}</span>
) : (
<Link to={paths.join('/')}>{route.breadcrumbName}</Link>
);
};
shouldComponentUpdate = () => {
return true;
};
componentDidUpdate = (prevProps: RouteComponentProps) => {
if (prevProps !== this.props) {
this.setState({
routes: this.props.breadcrumb
});
}
};
render() {
return (
<div style={{ color: 'red' }}>
<Breadcrumb
style={{ fontWeight: 600, fontSize: '15px', color: 'black' }}
separator={
<RightOutlined
style={{ transform: 'scalex(0.7)', fontSize: '16px' }}
/>
}

{this.state.routes.map((route, index) => {
return (
<Breadcrumb.Item key={index} href={`${route.path}`}>
{`${route.breadcrumbName}`}
{/* <HomeOutlined /> */}
</Breadcrumb.Item>
);
})}
</Breadcrumb>
</div>
);
}
}
const mapDispatchToProps = {
updateBreadcrumb: updateBreadcrumb
};
const mapStateToProps = (state: any) => {
return {
breadcrumb: state.breadcrumb.breadcrumb || []
};
};
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Render));

上面的代码我想写测试用例，但我无法安装它。我试着安装它，但它没有创建快照，它正在提供测试用例失败。请指导我正确的方向或一些文档。我真的是新手，我的公司给了我写测试用例的任务，但我在任何地方都找不到任何相关文档。

import React from 'react';
import Enzyme, { shallow, mount } from 'enzyme';
import Componnent from '../breadcrumb';
import { BrowserRouter as Router } from 'react-router-dom';
import configureStore from 'redux-mock-store'; //ES6 modules
import { Provider } from 'react-redux';
import thunk from 'redux-thunk';
import renderer from 'react-test-renderer';
import Adapter from 'enzyme-adapter-react-16';
Enzyme.configure({
adapter: new Adapter()
});
const setUp = (initprops:any) => {
const wrapper = mount(<Router><Provider store={initprops}><Componnent /></Provider></Router>);
return wrapper;
};
describe('Login Component', () => {
const middlewares = [thunk];
const mockStore = configureStore(middlewares);
const initialState = {};
const props = mockStore(initialState);
let wrapper:any,instancewrapper:any;
beforeEach(() => {
wrapper = setUp(props); 
instancewrapper = wrapper.instance();
});
it('should render correctly', () => {
const tree = renderer.create(<Router><Provider store={props}><Componnent /></Provider></Router>).toJSON();
expect(tree).toMatchSnapshot();
});
});

您仍然可以shallow渲染组件，并使用.dive()函数来打开主组件。
