Reactjs 测试是否调用常量模态组件
我有一个页脚组件,上面有几个按钮。所有这些按钮都使用Reactjs 测试是否调用常量模态组件,reactjs,jestjs,enzyme,antd,Reactjs,Jestjs,Enzyme,Antd,我有一个页脚组件,上面有几个按钮。所有这些按钮都使用消息常量,这是一种antd模式: Message.jsx import { Modal } from 'antd'; const { confirm } = Modal; export const Message = (text, okayHandler, cancelHandler) => { confirm({ title: text, okText: 'Yes', cancelText: 'No',
消息
常量,这是一种antd模式:
Message.jsx
import { Modal } from 'antd';
const { confirm } = Modal;
export const Message = (text, okayHandler, cancelHandler) => {
confirm({
title: text,
okText: 'Yes',
cancelText: 'No',
onOk: okayHandler,
onCancel: cancelHandler,
});
};
export default Message;
class Footer extends Component {
state = {
from: null,
redirectToReferrer: false,
};
cancelClicked = () => {
Message('Return to the previous screen?', () => {
this.setState({ redirectToReferrer: true, from: '/home' });
});
};
render() {
const { redirectToReferrer, from } = this.state;
if (redirectToReferrer) {
return <Redirect to={{ pathname: from }} />;
}
return (
<Card style={footerSyles}>
<Button
bounds={`${(3 * width) / 7 + (7 * width) / 84},5,${width / 7},30`}
text="CANCEL"
type="primary"
icon="close"
actionPerformed={this.cancelClicked}
/>
</Card>
//actionPerformed is actually onClick, it's taken as a prop from my <Button /> component. Card is an antd component while button is not.
Footer.jsx
import { Modal } from 'antd';
const { confirm } = Modal;
export const Message = (text, okayHandler, cancelHandler) => {
confirm({
title: text,
okText: 'Yes',
cancelText: 'No',
onOk: okayHandler,
onCancel: cancelHandler,
});
};
export default Message;
class Footer extends Component {
state = {
from: null,
redirectToReferrer: false,
};
cancelClicked = () => {
Message('Return to the previous screen?', () => {
this.setState({ redirectToReferrer: true, from: '/home' });

};
render() {
const { redirectToReferrer, from } = this.state;
if (redirectToReferrer) {
return <Redirect to={{ pathname: from }} />;

类页脚扩展组件{
状态={
from:null,
转发者:错,
};
取消单击=()=>{
消息('返回上一屏幕?',()=>{
this.setState({redirectoreFerrer:true,from:'/home'});
});
};
render(){
const{redirectToReferrer,from}=this.state;
if(重定向转发器){
返回;
}
返回(
//actionPerformed实际上是onClick,它是我的组件中的一个道具。卡是一个antd组件,而按钮不是。
我只想测试单击按钮时调用取消单击。如果可能,我想测试在模式上单击“确定”按钮时状态是否正确更改。我的测试如下,但测试失败,因为未调用函数:
页脚测试
const defaultFooter = shallow(<Footer position="relative" bounds="10,0,775,100" />);
test('Footer should open a popup when cancel button is clicked, and redirect to home page', () => {
const instance = defaultFooter.instance();
const spy = jest.spyOn(instance, 'cancelClicked');
instance.forceUpdate();
const p = defaultFooter.find('Button[text="CANCEL"]');
p.simulate('click');
expect(spy).toHaveBeenCalled();
});
constdefaultfooter=shallow();
测试('单击“取消”按钮时,页脚应打开一个弹出窗口,并重定向到主页',()=>{
const instance=defaultFooter.instance();
const spy=jest.spyOn(实例'cancelClicked');
forceUpdate();
const p=defaultFooter.find('Button[text=“CANCEL”]”);
p、 模拟(“点击”);
期望(间谍)。已被调用();
});
我也尝试使用mount而不是shallow,但是spy仍然没有被调用。说“即使名称暗示这模拟了一个实际事件,.simulate()实际上会根据您给它的事件以组件的道具为目标。例如,.simulate('click')实际上会获得onClick道具并调用它。”
这种行为可以在Enzyme
源代码和代码中看到
因此,行p.simulate('click');
最后尝试调用按钮的onClick
属性,该属性不存在,因此它实际上什么也不做
来自Airbnb的开发人员建议直接调用道具并避免simulate
在这种情况下,您可以直接调用actionPerformed
属性,如下所示:
p.props().actionPerformed();
按钮的组件从哪里来?它不是本地的
可能需要用onClick
替换actionPerformed
。
