AngularJs，Karma，Jasmine，为什么测试用例在这个场景下服务不可用？
AngularJs, Karma, Jasmine, Why are services not available under this scenario for test case?
我正在使用 grunt 和 运行 一个业力任务。我的单元测试用例配置为 karma/jasmine。似乎一切都应该到位，但我的一个服务不会加载。
下面的constanstsservice导致错误
(function() {
'use strict';
/**

beforeEach(module('registration'));
var scope = null;
var constantService = null;

beforeEach(inject(function($rootScope) {

console.log('Before test[1]!! : ');

不是在每个块之前注入 $injector，而是注入服务本身，如下所示：
beforeEach(inject(function(ConstantsService) {
var serv1 = ConstantsService;
console.log('Before test[2]!! : ');
}));
问题也可能是您过多地包含了脚本并且您的模块定义被覆盖了，特别是在本节中
'app/scripts/*.js',
'app/scripts/**/*.js',
'app/modules/**/*.js',
'app/app.js',
'../test/**/*.js',
'app/scripts/services/applicationConstants.js',
如果您检查 angularjs 生成的 the error url，您可以看到以下模式可以消除注册：
angular.module('myModule', [])
.service('myCoolService', function () { /* ... */ });
angular.module('myModule', [])
// myModule has already been created! This is not what you want!
.directive('myDirective', ['myCoolService', function (myCoolService) {
// This directive definition throws unknown provider, because myCoolService
// has been destroyed.
}]);
这可能与您包含文件的方式有关
