1.引入enzyme 的mount
2.引入jsdom
3.调用simulate 模拟操作
4.断言结果是否是预期
import {mount} from 'enzyme';
import { expect } from 'chai';
import React,{Component} from 'react';
import ReactDOM from 'react-dom';
import jsdom from 'jsdom'
const doc = jsdom.jsdom('<!doctype html><html><body></body></html>')
global.document = doc
global.window = doc.defaultView
class App extends Component {
constructor(props) {
super(props)
this.state = {
count: 1
}
}
render() {
return <h1 onClick={()=>{ this.setState({
count: this.state.count + 1
}) }}>{this.state.count}</h1>
}
}
function shallowRender(Component) {
const renderer = TestUtils.createRenderer();
renderer.render(<Component/>);
return renderer.getRenderOutput();
}
describe('Shallow Rendering',function () {
it('countTest',function () {
let app = mount(<App/>);
app.find('h1').simulate('click');
expect(app.find('h1').text()).to.equal('2');
});
});
