测试中间件功能

Question

我正在尝试为下面的类似中间件模块创建测试。我正在使用摩卡＆amp;柴，我被困在如何从测试文件中实际调用module.exports = function(){ var middleware = {}; middleware.doSomething= function(temp) { return temp; } return middleware; }; 函数。有关如何做的任何建议？

middleware.js

var foo = require('./middleware');
var assert = require('chai').assert;
describe('middleware test', function() {
    it('doSomething test', function(done) {
        //call the doSomething function
    });
});

test.js
