一、用到的工具
1.React.addons.TestUtils
2.Jasmine
3.Browserify(处理jsx文件的require依赖关系)
4.Reactify(能和browserify很好的配合,把jsx转换为js)
5.编译命令为 browserify -t reactify test.jsx > app.js (参数t为transform)
二、测试代码:
1.test.jsx
1 var React = require("react/addons"); 2 var TestUtils = React.addons.TestUtils; 3 var CheckboxWithLabel = require("./CheckboxWithLabel.jsx"); 4 5 describe("test CheckboxWithLabel component", function () { 6 it("check label text", function () { 7 var checkbox = TestUtils.renderIntoDocument(<CheckboxWithLabel text="你是否爱吃橘子" on="爱吃" off="不爱吃"></CheckboxWithLabel>); 8 var text = React.findDOMNode(checkbox).textContent; 9 expect(text).toContain("你是否爱吃橘子1"); 10 }) 11 })
2.CheckboxWithLabel.jsx
1 var React = require('react/addons'); 2 var CheckboxWithLabel = React.createClass({ 3 getInitialState: function () { 4 return { 5 checked: false 6 } 7 }, 8 onChange: function() { 9 this.setState({ 10 checked: !!this.state.checked 11 }); 12 }, 13 render: function() { 14 return ( 15 <label> 16 {this.props.text} 17 <input type = "checkbox" checked={this.state.checked} onChange={this.onChange}/> 18 {this.checked ? this.props.on : this.props.off} 19 </label>); 20 } 21 }); 22 23 module.exports = CheckboxWithLabel;
3.index.html
1 <!DOCTYPE html> 2 <html lang="zh-cn"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>测试</title> 6 </head> 7 <body> 8 <link rel="stylesheet" href="./node_modules/jasmine.css"> 9 <script src="./node_modules/jasmine.js"></script> 10 <script src="./node_modules/jasmine-html.js"></script> 11 <script src="./node_modules/boot.js"></script> 12 <script src="./app.js"></script> 13 </body> 14 </html>
三、运行结果
1.
2.若修改测试代码为expect(text).toContain("你是否爱吃橘子1"),则如下:
