angularjs 路由单元测试 [英] angularjs route unit testing

问题描述

正如我们在 http://docs.angularjs.org/tutorial/step_07 中看到的,

As we see here in http://docs.angularjs.org/tutorial/step_07,

angular.module('phonecat', []).
  config(['$routeProvider', function($routeProvider) {
  $routeProvider.
      when('/phones', {templateUrl: 'partials/phone-list.html',   controller: PhoneListCtrl}).
      when('/phones/:phoneId', {templateUrl: 'partials/phone-detail.html', controller: PhoneDetailCtrl}).
      otherwise({redirectTo: '/phones'});
}]);

路由测试建议使用e2e测试，

routing test is suggested to be done with e2e test,

  it('should redirect index.html to index.html#/phones', function() {
    browser().navigateTo('../../app/index.html');
    expect(browser().location().url()).toBe('/phones');
  });

但是，我认为$routeProvider"配置是通过单个函数 function($routeProvider) 完成的，我们应该能够在不涉及浏览器的情况下进行单元测试，因为我认为路由函数不需要浏览器 DOM.

However, I think the '$routeProvider' config is done with a single function, function($routeProvider), and we should be able to unit test without involvement of browser since I think routing function does not require browser DOM.

例如，
当 url 为/foo 时，templateUrl 必须为/partials/foo.html 并且控制器为 FooCtrl
当 url 为/bar 时，templateUrl 必须为/partials/bar.html，控制器为 BarCtrl

For example,
when url is /foo, templateUrl must be /partials/foo.html and controller is FooCtrl
when url is /bar, templateUrl must be /partials/bar.html and controller is BarCtrl

这是一个简单的函数 IMO，它也应该在一个简单的测试中进行测试，一个单元测试.

It is a simple function IMO, and it should also be tested in a simple test, a unit test.

我用谷歌搜索并搜索了这个 $routeProvider 单元测试，但还没有运气.

I googled and searched for this $routeProvider unit test, but no luck yet.

我想我可以从这里借用一些代码，但还没有完成，https://github.com/angular/angular.js/blob/master/test/ng/routeSpec.js.

I think I may borrow some code from here but couldn't make it yet, https://github.com/angular/angular.js/blob/master/test/ng/routeSpec.js.

推荐答案

为什么不直接断言路由对象配置正确?

Why not just assert the route object is configured correctly?

it('should map routes to controllers', function() {
  module('phonecat');

  inject(function($route) {

    expect($route.routes['/phones'].controller).toBe('PhoneListCtrl');
    expect($route.routes['/phones'].templateUrl).
      toEqual('partials/phone-list.html');

    expect($route.routes['/phones/:phoneId'].templateUrl).
      toEqual('partials/phone-detail.html');
    expect($route.routes['/phones/:phoneId'].controller).
      toEqual('PhoneDetailCtrl');

    // otherwise redirect to
    expect($route.routes[null].redirectTo).toEqual('/phones')
  });
});
