问题描述
有关AngularJS单元测试希望简单的问题。我用一个简单的服务（改编自角种子工程）控制器
A hopefully simple question about AngularJS unit testing. I have a controller using a simple service (adapted from angular-seed project)
services.js：
angular.module('myApp.services', []).value('version', '0.1');
controllers.js：
function MyCtrl1($s, version) {
$s.version = version;
}
MyCtrl1.$inject = ["$scope","version"];
这伟大工程的IM我的应用程序。不过，我有麻烦创建单元测试框架的工作控制器。我想不出我们如何注入'版本'服务（或创建实例），并把它传递给$控制器（）工厂 - 我认为这就是我想做的事情？下面是裸露的骨头规格：
This works great im my app. However, I have trouble creating the controller in unit test frame work. I can't figure our how to inject 'version' service (or create instance) and pass it to $controller() factory - I assume that's what I want to do?! Here's the bare bones spec:
controllerSpec.js
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new();
// how about version service?
ctrl = $controller(MyCtrl1, {$scope: scope, /* version: <where from?> */});
}));
it('Version should be 0.1 ...', function() {
expect(scope.version).toBe('0.1');
});
运行测试工具收益率：

错误：未知提供商：versionProvider＆LT; - 版本的
我曾尝试与喷油$ / $提供商和模块（），但无济于事各种事情。我敢肯定的答案很简单，但我无法看到它。
I have tried various things with $injector/$provider and module() but to no avail. I'm sure the answer is simple, but I can't see it.
推荐答案
只是添加 beforeEach（模块（'myApp.services'））来形容你的块。这将与版服务加载服务模块插入测试喷油器，并且将其提供给您的测试。
just add beforeEach(module('myApp.services')) to your describe block. This will load the services module with the "version" service into the test injector and that will make it available to your test.
