使用Jasmine测试时在全球范围内注入AngularJS工厂模型 [英] Globally injecting am AngularJS factory mockup when testing with Jasmine

问题描述

我正在为AngularJS应用程序的控制器创建单元测试。
在myapp.run中，我以某种方式注入并使用了一个名为UsersFactory的工厂：

I'm creating unit tests for my AngularJS application's controllers. In myapp.run I'm injecting and using a factory, called UsersFactory, somehow like this:

myApp.run(['$rootScope','UsersFactory', function ($rootScope,UsersFactory) {
    UsersFactory.getMe().then(function(data)
    {
        //..
    });
}]);

我为UsersFactory创建了一个名为UsersFactoryMock的Mock。它具有与UsersFactory相同的方法，但是实现方式是不同的（伪造的）。

I created a Mock for UsersFactory called UsersFactoryMock. It has the same methods as UsersFactory, but the implementation is different (fake) of course.

我想注入UsersFactoryMock，以便使myApp.run能够

I would like to inject UsersFactoryMock, in order to be able myApp.run to use it instead of UsersFactory.

我试图使用beforeEach来做到这一点：

I was trying to do so using beforeEach:

beforeEach(module(function ($provide, $injector)
{
    $provide.service("UsersFactory", $injector.get("UsersFactoryMock") );
}));

但是运行测试会告诉我，

But running the test, it tells me,

错误：[$ injector：modulerr]无法实例化模块功能（$ provide）
，原因是：
ReferenceError：未定义UsersFactoryMock

Error: [$injector:modulerr] Failed to instantiate module function ($provide) due to: ReferenceError: UsersFactoryMock is not defined"

我如何实现我的目标？

预先感谢。

推荐答案

UsersFactoryMock 是否需要向注入器注册？为什么不仅仅提供一个普通对象作为？
您的模拟游戏？

Does UsersFactoryMock need to be registered with the injector? Why not just provide a plain object as your mock?

var UsersFactoryMock = {
    getMe: function () {
        // mocked method
    }
};

beforeEach(module(function ($provide) {
    $provide.service("UsersFactory", UsersFactoryMock);
}));

此外，在运行块中测试代码通常比较混乱，您应该移动这样的逻辑进入服务，然后可以像其他任何服务一样对其进行测试。请参阅：https://stackoverflow.com/a/18089426/2943490 。

Moreover, testing code in a run block is generally messy. You should move such logic into a service which can then be tested like any other. See: https://stackoverflow.com/a/18089426/2943490.
