Question

在VS中阅读了关于javascript单元测试/ bdd之后我发现你可以使用以下组合：

- ReSharper - support for PhantomJS headless + Jasmine/QUnit
- Testr - mock Require dependencies

我在测试脚本中使用了Jasmine，并且能够成功运行一些简单的测试，并在同一个文件中声明了函数。

但是，我无法找到/构建一个工作端到端的示例来测试具有依赖关系的js模块。我试图建立在John Papa的SPA Jumpstart示例中使用的示例。

因此给出了一个在datacontext.js中具有依赖关系的people.js viewmodel模块：

define(['services/datacontext'],
 function (datacontext) {
var peopleViewModel = {        
                       title: 'People page'
                      };
return peopleViewModel;
})

文件夹结构：

/App/Viewmodels : people.js
/App/Services : datacontext.js
/App/Tests : peopletests.js

我需要在peopletests.js中添加什么才能运行此测试？

describe("My Tests Set", function () {
 it("People Title Test", function () {
   expect(peopleViewModel.title()).toEqual("People page");
 });
});

试试这个：

将require.js添加为参考路径
添加require.config脚本作为参考路径
load require modules。

peopletests.js：

/// <reference path="~/Scripts/require.js"/>
/// <reference path="~/App/requireConfig.js"/>

describe("My Tests Set", function () {
var people;

beforeEach(function () {
    if (!people) { //if people is undefined it will try to load it
       require(["people"], function (peopleViewModel) {
            people = peopleViewModel;
        });
        //waits for people to be defined (loaded)
        waitsFor(function () { 
            return people;
        }, "loading external module", 1000);
    }
});

 it("People Title Test", function () {
   expect(people.title).toEqual("People page");
 });
});

requireConfig.js：

//beware of the port, if your app is runing in port 8080 
//you need to specified that to require since resharper whould use a random port 
//when running tests 
require.config({
    baseUrl: 'http://localhost:8080/App/',
    paths: {
        people: 'ViewModels/people',
        dataContext: 'Services/datacontext'
    }
});

people.js

define(['dataContext'],
 function (datacontext) {
var peopleViewModel = {        
                       title: 'People page'
                      };
return peopleViewModel;
})

如何使用resharper testr jasmin测试spa js模块？
