Angular的新手，并从
我在角度测试中遇到TypeError而不确定问题是什么。这是我的测试：
（function（）{
'use strict';
describe（'测试DeliveriesController'，function（）{
beforeEach（module（'app.deliveries'））;
describe（'测试交付控制器'，函数（）{
var vm，controller;
beforeEach（inject（function（$ controller，$ rootScope）{
vm = $ rootScope。$ new（）;
controller = $ controller （'DeliveriesController'，{$ scope：vm}）;
}））;
afterEach（function（）{
vm = undefined;
controller = undefined ;
}）;
describe（'priority length'，function（）{
it（'它应该测试优先级长度'，函数（）{
expect （vm.priorities.length）.toBe（0）;
}）;
}）;
}）;
}）;
}）（）;
我得到的错误如下：
PhantomJS 1.9.8（Mac OS X 0.0.0）测试DeliveriesController测试交付控制器优先级长度它应该测试优先级长度FAILED
错误：[$ injector：unpr]未知提供者：DeliveriesServiceProvider< - DeliveriesService< - DeliveriesController

解决方案
礼貌：来自@StubbbOrn的评论：
你能展示控制器的代码吗？这将有助于更好地理解问题。看起来DeliveriesController不仅取决于$ scope，还取决于DeliveriesService。当你实例化控制器时，你应该提供它所有的依赖项（真实的或模拟的）。
这个解决方案适用于我并且是解决方案。谢谢@StubbOrn
New to Angular and following up from my earlier post from angularjs jasmine tests: Variable vm not foundI am having a TypeError in my angular tests and not sure what the problem is. Here is my test:
(function(){
'use strict';
describe('Testing DeliveriesController', function() {
beforeEach(module('app.deliveries'));
describe('Testing deliveries controller', function(){
var vm, controller;
beforeEach(inject(function($controller, $rootScope){
vm = $rootScope.$new();
controller = $controller('DeliveriesController', {$scope:vm});
}));
afterEach(function() {
vm = undefined;
controller = undefined;
});
describe('priorities length', function(){
it('it should test priority length', function () {
expect(vm.priorities.length).toBe(0);
});
});
});
});
})();
The error I get is as follows:
PhantomJS 1.9.8 (Mac OS X 0.0.0) Testing DeliveriesController Testing deliveries controller priorities length it should test priority length FAILED

Courtesy: comment from @StubbbOrn:
Could you show controller's code? It would help to understand problem better. Looks like DeliveriesController depends not only on $scope but also on DeliveriesService. When you instantiate controller you should provide it all dependencies (either real or mocked ones).
This solution worked for me and was the solution. Thanks @StubbOrn
