Question

我想写JS测试。生产代码使用RequireJS编写。我找到了一个名为Squire.js的测试库：https://github.com/iammerrick/Squire.js/

来自Squire.js网站

运行生成一个函数，该函数将接收完成回调并在测试功能完成后执行它。对于使用回调处理异步的框架特别有用。这是Mocha.js的一个例子。 Jasmine可以使用Jasmin.Async提供这种回调方法。“

我不知道如何在Jasmine async中使用它。一个小例子非常有用。

这是一个很好的设置，可以将带有模拟依赖项的模块插入到测试中。这是一个让某人开始的端到端示例，如果您只想查看规范，请跳到最后。

文件夹结构：

Jasmine
|-lib
||-jasmine          -- Contains all the Jasmine files
|||-boot.js
|||-jasmine-html.js
|||-jasmine.js
|||-jasmine.css
|||-jasmine_favicon.png
|||-...
|-spec              -- Spec files go here
||-hello-spec.js
|SpecRunner.html
|SpecRunner.js
|squire.js
Scripts
|knockout.js
|require.js
|jquery.js
App
|-hello.js
|-foo.js

在您提问时，Jasmine 1.3是最新版本。从那时起2.0发布并包含一些异步改进。这两个版本都包括在内，1.3已被注释掉。

这个问题Does Jasmine 2.0 really not work with require.js?有助于实现这一目标。

(function () {
    'use strict';

    // Configure RequireJS to shim Jasmine

        baseUrl: "../App",

            'knockout': '../Scripts/knockout-2.3.0',

        },
        shim: {

        }
    });

    // Define all of your specs here. These are RequireJS modules.
    var specs = [
      'spec/hello-spec'
    ];

    // Load Jasmine - This will still create all of the normal Jasmine browser globals unless `boot.js` is re-written to use the
    // AMD or UMD specs. `boot.js` will do a bunch of configuration and attach it's initializers to `window.onload()`. Because
    // we are using RequireJS `window.onload()` has already been triggered so we have to manually call it again. This will
    // initialize the HTML Reporter and execute the environment.
    require(['boot'], function () {

        // Load the specs
        require(specs, function () {

            // Initialize the HTML Reporter and execute the environment (setup by `boot.js`)
            window.onload();
        });
    });

    /******
     * Use this require if you're on Jasmine 1.3

    //require(['jquery', 'jasmine-html'], function ($, jasmine) {
    //  var jasmineEnv = jasmine.getEnv();
    //  jasmineEnv.updateInterval = 1000;

    //  var htmlReporter = new jasmine.HtmlReporter();

    //  jasmineEnv.addReporter(htmlReporter);

    //  jasmineEnv.specFilter = function(spec) {
    //      return htmlReporter.specFilter(spec);
    //  };

    //  $(function() {

    //          jasmineEnv.execute();

    //  });

行

var injector = new Squire();
var builder = injector
    .mock('foo', {
        message: "Hello, World!"
    });

模拟hello对foo的依赖然后

builder.require(['hello'], function (hi) {
    hello = hi;
    done(); // ...until you invoke it.
});

使用模拟的foo加载hello模块。比较使用require本身在第二个测试中加载hello：

 require(['hello'], function (hi) {
     hello = hi;
     done(); // ...until you invoke it.
 });

Jasmine docs http://jasmine.github.io/可以填写“done（）”功能（2.0）或“runs / waititsFor”（1.3）。
