我正在努力将 JavaScript 单元测试包含到我正在处理的 ASP.NET 项目中。我已经安装了 Chutzpah 适配器和 Jasmine。在仔细按照此 Ryan Cromwell 视频提供的安装和设置环境的指导后，我遇到了与此帖子类似的错误，即 Chutzpah 和 QUnit的问题，但是我使用的是 Jasmine 而不是 QUnit，他的解决方案似乎没有应用，至少不是以同样的方式。

这是正在测试的 JavaScript (WebApp.Utils.js)。正在测试的函数是使用“显示模块”模式定义的 WebApp.Utils“类”的方法（不确定这是否相关）......

var WebApp = (typeof WebApp === "undefined") ? { } : WebApp ;

$(document).ready(function () {

    WebApp .Utils = (function () {

        var ParseDecimal = function (value, decimalPlaces) {
            /// <summary>Parses a number into a decimal value with the specified number of decimal places</summary>
            /// <param name="value" type="number">Number to parse</param>
            /// <param name="decimalPlaces" type="integer">Number of decimal places to parse to. </param>
            ///
            return parseFloat(Math.round(value * 100) / 100).toFixed(decimalPlaces);
        }

        return {

            ParseDecimal: ParseDecimal
        }

    })();

});

这是编写的测试，使用Jasmine进行测试。文件引用已被验证为正确。事实上，IntelliSense 正在工作，所以我知道它可以看到它。

/// <reference path="../tools/jasmine.js" />
/// <reference path="../shared/WebApp.Utils.js" />
/// 

describe("WebApp.Utils.ParseDecimal", function () {


    it("can ParseDecimal", function () {        
        var result = WebApp.Utils.ParseDecimal(15.451222, 2);
        expect(result).toBe(15.45);
    });
});

这是我在保存文件并运行测试时得到的错误是 Visual Studio。

事实证明，Chuztpah 不识别根级引用（相对于相对引用）。您在我提供的代码中没有看到的是 WebApps.Utls.js 文件还包含对

/// <reference path="/Scripts/jquery/_references.js" />
/// <reference path="/Scripts/tools/modernizr-2.6.2.js" />
/// <reference path="/Scripts/tools/_references.js" />

这些其他参考文件反过来又提供了与 Knockout、jquery 等工具的链接。一旦我将这些单独的相对引用提供到我的 Jasmine 测试文件的顶部，一切正常。

/// <reference path="../../jquery/jquery-2.0.3.js" />
/// <reference path="../../tools/jasmine.js" />
/// <reference path="../../tools/knockout-2.1.0.debug.js" />
/// <reference path="../../tools/modernizr-2.6.2.js" />
/// <reference path="../../tools/jshashset_src.js" />
/// <reference path="../../tools/jshashtable-2.1.js" />
/// <reference path="../../tools/json2.js" />
/// <reference path="../../Models/ServiceLevelDTO.js" />
/// <reference path="../../shared/WebApp.Utils.js" />
