Javascript 如何从intern.js测试中加载node.js http模块?
我正在尝试使用Intern测试框架来自动测试一个使用node.js和StrongLoop实现的简单REST API。StrongLoop提供了一个浏览器网页,我用它来验证RESTAPI是否已实现,我可以从Postman手动测试API 我尝试使用intern.js进行的第一个API测试检索集合中媒体对象的计数。HTTP方法是GET,URL是Javascript 如何从intern.js测试中加载node.js http模块?,javascript,node.js,unit-testing,rest,intern,Javascript,Node.js,Unit Testing,Rest,Intern,我正在尝试使用Intern测试框架来自动测试一个使用node.js和StrongLoop实现的简单REST API。StrongLoop提供了一个浏览器网页,我用它来验证RESTAPI是否已实现,我可以从Postman手动测试API 我尝试使用intern.js进行的第一个API测试检索集合中媒体对象的计数。HTTP方法是GET,URL是http://localhost:3000/api/media/count并且响应为{“count”:2} 当我运行intern.js测试时,我收到一个错误“错

并且响应为{“count”:2}
当我运行intern.js测试时,我收到一个错误“错误:尝试要求卸载模块http”
我在node.js应用程序中有一个\tests子目录。我的测试用例是media.js:
define([
'intern!object',
'intern/chai!assert'
], function (registerSuite, assert, media) {
registerSuite({
name: 'media',
count: function() {
var http = require("http");
var request = http.request;
request({
url: "http://localhost:3000/api/media/count",
method: "GET"
}, function (error, response, body) {
console.log("Status", response.statusCode);
console.log("Headers", JSON.stringify(response.headers));
console.log("Response received", body);
});
assert.strictEqual(body, '{"count": 2}',
url + ' should return 2 items');
}
});
});

我的理解是http模块是一个核心模块,它是随node.js自动安装的,但是我想知道intern.js是否尽管基于节点,但不允许在没有额外配置的情况下访问核心模块。这是合理的,但是我已经看过intern.js教程和intern.js配置指南,但是没有找到一种方法来添加引用或依赖项,以便测试用例能够成功加载node.js http模块。我是intern.js的新手,所以我没有正确配置它或测试
我欢迎任何关于我做错了什么的意见/见解
致以最良好的祝愿
MWIntern在AMD环境中运行其测试,因此
require
是AMD加载程序的require
,而不是节点的,因此您会出错
要加载节点模块,请使用intern/dojo/Node代码>AMD插件
define([
...,
'intern/dojo/node!http'
], function (..., http) {
// Now http contains the exports of Node's http module
});
