javascript - 如何使用 resharper testr jasmin 测试 spa js 模块？

Question

在阅读了 VS 中的 javascript 单元测试/bdd 之后，我发现您可以使用以下组合:

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

我在测试脚本中使用了 Jasmine，并能够成功运行一些简单的测试，并在同一文件中声明了函数。

但是，我无法找到/构建一个工作端到端示例来测试具有依赖项的 js 模块。我正在尝试以 John Papa 的 SPA Jumpstart 示例中使用的示例为基础。

因此，给定一个在 datacontext.js 中具有依赖项的 people.js View 模型模块:

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:

1. 添加 require.js 作为引用路径
2. 添加 require.config 脚本作为引用路径
3. 加载需要的模块。

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;
})
