[英]How to do unit testing using Jest and enzyme for these type of code segmentations?
[英]How to do testing with Relay modern with jest and enzyme?
如何用 jest 和 enzyme 测试这种文件...
class App extends React.Component{ constructor(){ super() } render(){ const { viewer, children, isLoading } = this.props return( <div> <div id="container"> {children} </div> {isLoading && <Loading />} </div> ); } } export default createFragmentContainer( App, graphql` fragment App_viewer on User{ id email } ` )
你可以这样做
const React = require('React');
const App = require('App.react');
jest.mock('react-relay', () => ({
createFragmentContainer: App =>
App,
}));
const {shallow} = require('enzyme');
const {shallowToJson} = require('enzyme-to-json');
describe('App', () => {
it('renders the dashboard section correctly', () => {
const wrapper = shallow(
< App
title="Test Dashboard Section"
charts={[]}
/>,
);
expect(shallowToJson(wrapper)).toMatchSnapshot();
});
我们需要模拟 react-relay。 正如刚才提到的。
