Question

我正在尝试使用mocha和chai

创建逻辑测试

var helperFunctions = require('../lib/helperfunctions.js');
var expect = require('chai').expect;

suite('Sample logic tests',function(){
    test('getDynamicContent() should return dynamic content',function(){
       console.log(typeof helperFunctions.getDynamicContent()); // string
       expect(false); //Doesnt seem to do anything
       expect(typeof helperFunctions.getDynamicContent() === 'number'); 
    });
});

我的helperFunctions.js：

exports.getDynamicContent = function(){

    var dynamicContentSource = [
        "Dynamic Content 1",
        "Dynamic Content 2",
        "Dynamic Content 3",
        "Dynamic Content 4",
        "Dynamic Content 5"
    ];
    var randomDynamicContent = dynamicContentSource[Math.floor(Math.random()*dynamicContentSource.length)];
    return randomDynamicContent;
};

出于某种原因，我的测试总是通过，即使typeof helperFunctions.getDynamicContent（）是一个字符串。

有人可以向我解释我还没有理解的内容吗？

你可以使用像上面评论所说的匹配器。例如expect().to.be.equal()

＆＃34;期望＆＃34;工作？
