我目前正在尝试评估与 React 一起使用的不同测试框架,结果发现 Jest 在我的列表中。但是,我正在尝试使用此处概述的静态属性:https ://github.com/jeffmo/es-class-fields-and-static-properties 。
因此,我采用了 Jest 主页上提供的教程,并添加了一个静态 propTypes 属性,我的代码如下所示:
import React from 'react';
class CheckboxWithLabel extends React.Component {
static defaultProps = {}
constructor(props) {
super(props);
this.state = {isChecked: false};
// since auto-binding is disabled for React's class model
// we can prebind methods here
// http://facebook.github.io/react/blog/2015/01/27/react-v0.13.0-beta-1.html#autobinding
this.onChange = this.onChange.bind(this);
}
onChange() {
this.setState({isChecked: !this.state.isChecked});
}
render() {
return (
<label>
<input
type="checkbox"
checked={this.state.isChecked}
onChange={this.onChange}
/>
{this.state.isChecked ? this.props.labelOn : this.props.labelOff}
</label>
);
}
}
module.exports = CheckboxWithLabel;
当我运行测试(npm test 或 jest)时,它会引发以下错误:
➜ jest
Using Jest CLI v0.8.2, jasmine1
FAIL __tests__/CheckboxWithLabel-test.js
● Runtime Error
SyntaxError: Desktop/jest/examples/react/CheckboxWithLabel.js: Unexpected token (5:22)
我的 package.json 文件如下所示:
{
"dependencies": {
"react": "~0.14.0",
"react-dom": "~0.14.0"
},
"devDependencies": {
"babel-jest": "*",
"babel-preset-es2015": "*",

],

}
}
关于我在这里缺少什么的任何想法?
谢谢。
