angularjs - Angular mock 找不到我的控制器，无法在 grunt 下使用 Karma 和 Requirejs 运行 js 单元测试

Question

这是我在 Git Hub 中的示例代码：

https://github.com/Mellon/KarmaWithRequirejs.git

运行“grunt test”时，出现此错误。

Error: [ng:areq] Argument 'MyController' is not a function, got undefined

define(['expect'], function () {
    'use strict';
    describe('MyController', function () {
        var controllerContructor, scope, controller;
        before(function () {//change before to beforeEach, it works.
            module('app');
            inject(function ($controller, $rootScope) {
                controllerContructor = $controller;
                scope = $rootScope.$new();
                controller = controllerContructor('MyController', {$scope: scope});
            });
        });

        it('shoule be loaded.', function () {
            expect(controller).to.be.an('object');
        });
    });
});
