Question

我正在使用Webpack来修改我的角度js代码。但是我无法编写基于mocha的单元测试用例bcz gulp-mocha未能“需要”css。以下是有关详细信息的代码段。

Benefits.js angular js指令：

var Utilities = require("./../../../../../utilities/Utilities");
var AppUtilities = require("./../../../../../utilities/AppUtilities");
require("./../../../../css/benefits.css");
module.exports = {
    getBenefits: function ($sce) {
        return {
            restrict: "E",
            template: require('html!./../../../../templates/page/Benefits.html'),
            replace: true,
            scope: {
                benefits: '=',
                productPageBenefits: '=',
                divider: '='
            },
            link: function (scope, element, attrs) {

                //get benefit details as per given list of key
                scope.getBenefitsList = function (benefitKeyList, benefits) {
                    return OpensiteUtilities.getBenefitsList(benefitKeyList, benefits);
                };

            }
        };
    }
};

Benefits_test.js是单元测试用例文件：

describe('The Benefits', function () {
    var Benefits = require('../../../../../../../../application/client-src/js/application/directives/productpage/Benefits.js');

    beforeEach(function () {

    });

    it('Should be an Object', function () {
        Benefits.should.be.a('Object');
        expect(Benefits).to.have.property('getBenefits');       
    });

});

我出现错误

/my/path/application/client-src/css/benefits.css:1
(function (exports, require, module, __filename, __dirname) { @media (min-widt
                                                              ^

  showStack: false,
  showProperties: true,
  plugin: 'gulp-mocha' }

我理解它失败的bcz gulp-mocha无法理解“css”文件。我怎么写测试用例？我是否在指令代码之外移动了“require(./../benefits.css)”？

我希望将所有依赖项保存在相同的指令代码中（使用webpack）。请帮忙

一种选择是通过mocha-loader触发Mocha并将CSS设置为通过null-loader加载。这应该可以解决您遇到的require问题。

如果你想在Webpack之外解决它，你需要以某种方式修补require。在这种情况下，我希望您能使用proxyquire，mockery或rewire之类的内容。

单元测试用例无法加载基于webpack的js文件，需要加载css
