我对此很疯狂，我无法进行相当简单的单元测试（这是我在AngularJS上的第一个）。
我保持一切尽可能简单。我一直在尝试几种方式来注入我的服务，但他们都没有工作。我尝试的最后一个来自here。
这是我的测试文件：
describe('product service',function(){
var ProductService;
beforeEach(module('inspinia'));
beforeEach(inject(function (_ProductService_) {
ProductService = _ProductService_;
}));
describe('Test',function(){
it("should be aware that true is true", function() {
expect(true).toBe(true);
});
});
});
这是我的服务：

这是我尝试运行测试时遇到的错误：

如果我删除了我尝试注入服务的行，测试通过了，所以我认为其他一切都很好。

答案 0 :(得分：1)
你这么说
after removing the lines where I try to inject my service, the test passes
因为您的测试用例没有使用任何angular mocking stuff。
他们纯粹使用Jasmine stuff。
这意味着你的 angular-mocks.js没有被加载。
我已使用相同的代码进行了检查，唯一的区别是加载angular-mocks.js库。
请检查angular-mocks.js中karma_config file的路径。
在Karma config中查看基本路径后，angular-mocks.js的路径应该与此angular/angular.min.js一样。
如果您的node_modules位于angular文件夹之外，请使用此路径'../node_modules/angular-mocks/angular-mocks.js'。
编辑：请更新此内容。
files: [
'js/angular/angular.min.js',
'node_modules/angular-mocks/angular-mocks.js',
'js/app-services/*.js',
'js/app.js',
'js/app-services-tests/*.js'
],
更新：
嗯，解决方法是，您应该定义one main module which is your ng-app。
然后为服务，控制器等各项创建模块，并将它们注入一个模块。
考虑到这些，为ProductService＆amp;定义一个模块。相关服务， serviceModule。
angular.module('serviceModule',[]) //service.js
将其注入主模块
var app = angular.module('inspinia',['serviceModule']) // app.js
