Question

我正在使用Angular 1.5.8。这是我的代码：

describe('My Controller', function() {
    var MyController;
    var $controller;
    var $rootScope;
    var $state;

    beforeEach(angular.mock.module('ui.router'));
    beforeEach(module('app.my.ctrl'));
    beforeEach(inject(function(_$controller_, _$rootScope_, _$state_) {
        $controller = _$controller_;
        $rootScope = _$rootScope_;
        $state = _$state_;
        MyController = $controller('MyController', { scope: $rootScope.$new() });
    }));

    describe('#init', function() {
        it('should do something', function() {
            console.log('logStatement', MyController);

            MyController.init();

            expect(true).toBe(true);
        })

    })
});

测试运行器能够找到所有文件，所以这不是忘记加载某些东西的情况。当我运行此测试时，不仅logStatement不会出现，我也会收到此错误：

Argument 'MyController' is not a function, got undefined

这是我的控制者：

(function() {
'use strict';

angular
    .module('app.my.ctrl')
    .controller('MyController', MyController);

MyController.$inject = [
    '$scope'
];
/* ngInject */
function MyController($scope) {

    var vm = this;

    vm.hello = 'world';

    vm.init = function() {
        return true;
    }
}

})();

这是我的业力配置文件：

// Karma configuration

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser
    files: [
      'bower_components/angular/angular.js',
      'bower_components/angular-mocks/angular-mocks.js',
      'bower_components/angular-ui-router/release/angular-ui-router.js',
      'src/controllers/MyController.js',
      'tests/unit/**/*.spec.js',
    ],


    // list of files to exclude
    exclude: [
      '**/*.swp'
    ],


    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
    },


    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter
    reporters: ['spec'],

    //  Spec Reporter Config
    specReporter: {
    //     suppressErrorSummary: false,
    //     suppressFailed: false,
    //     suppressPassed: false,
        suppressSkipped: true
    //     showSpecTiming: false
    },


    // web server port
    port: 9876,


    // enable / disable colors in the output (reporters and logs)
    colors: true,


    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,


    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,


    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: true,

    // Concurrency level
    // how many browser should be started simultaneous
    concurrency: Infinity
  })
};

这是什么意思？我在文档中找不到任何可以解释这一点的内容。

我看过this answer但答案没有用。

尝试将控制器中注入的服务从scope更改为$scope

beforeEach(inject(function(_$controller_, _$rootScope_, _$state_) {
      $controller = _$controller_;
      $rootScope = _$rootScope_;
      $state = _$state_;
      MyController = $controller('MyController', { $scope: $rootScope.$new()});
}));

您是否尝试使您的pb尽可能简单？在应用程序内部，您可以成功拨打此电话吗？ $controller('MyController', { $scope: $rootScope.$new()});。如果这有效（它实际应该），问题肯定来自你的test / jasmin / karma / gulp / grunt配置，你不应该再深入挖掘角度方向了。您能否介绍一下如何在应用程序中定义app.my.ctrl模块？也许这个模块依赖于更多的模块，而不仅仅是你在测试中模拟的ui.router。如果是这种情况，则无法加载模块，也无法创建任何内部控制器。

describe('My Controller', function() {
  var MyController;
  var scope;

  beforeEach(angular.mock.module('ui.router'));
  beforeEach(module('app.my.ctrl'));
  beforeEach(inject(function($rootScope) {
      scope = $rootScope.$new();
  }));

  describe('#init', function() {
      it('should do something', function($componentController) {
          var MyController = $componentController('MyController', {
                $scope : scope
            });
          MyController.init();

          expect(true).toBe(true);
      })

  })
});

加载控制器时$ controller service抛出错误
