测试时初始化的依赖关系不存在 [英] Initialized dependency not present when testing

问题描述

我正在使用ember-cli 0.0.35，并通过一个初始化器将一个依赖项注入到我的组件上。它在开发中运行良好，但是当我运行测试时，该属性不存在。看来测试调用loadInitializers，但依赖关系并没有显示在这个.subject（{}）;

我不想手动注入它来进行测试。有更好的方法来处理吗？

初始化程序：

  var FooServiceInitializer = {
 name：'foo'，
 initialize：function（container，application）{
 application.inject（'component：foo'，'foo '，'service：foo'）; 
} 
}; 
导出默认FooServiceInitializer; 
  

失败测试：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b b component = this.subject（{}）;
}，
teardown：function（）{
Ember.run（App，App.destroy）;
}
}）;

test（'Properties：foo'，function（）{
//确保我们注入了服务
ok（component.foo，'foo is inject'）;
}）;

解决方案

正如我之前所说，它真的适合于您在此时测试容器（而不是由ic-ajax创建的迷你容器）进行集成测试。

您的实际测试符合

  test（root lists 3 colors，function（）{
 var c = App .__ container __。lookup ：foo-bar'）; 
 ok（c.foo.blah）; 
}）; 
  

如果您在测试期间使用容器感到内疚（您不应该），您可以创建一个帮助者，以避免在/将来api发生变化时，将其全部修复。

  Ember.Test.registerHelper （'containerLookup'，
 function（app，look）{
 return app .__ container __。lookup（look）; 
} 
）; 
  

确保您在

  App.injectTestHelpers（）; 
  

然后你的测试看起来像

  test（root list 3 colors，function（）{
 var c = containerLookup（'component：foo-bar'）; 
 ok（c.foo .blah）; 
}）;

I'm using ember-cli 0.0.35, and injecting a dependency onto my component via an initializer. It works great in development, but the property isn't present when I run tests. It appears that testing calls loadInitializers, but the dependency is not showing up on this.subject({});

I don't want to manually inject it for the tests. Is there a better way to handle this?

Initializer:

var FooServiceInitializer = {
  name: 'foo',
  initialize: function (container, application) {
   application.inject('component:foo', 'foo', 'service:foo');
  }
};
export default FooServiceInitializer;

Failing Test:

moduleForComponent('bar', 'Component: Bar', {
  setup: function() {
    App = startApp();
    component = this.subject({});
  },
  teardown: function () {
    Ember.run(App, App.destroy);
  }
});

test('Properties: foo', function() {
  // Make sure we injected the service
  ok(component.foo, 'foo is injected');
});

解决方案

As I said before, it really lends itself to an integration test since you are testing the container at this point (and not the mini container created by ic-ajax).

Your real test is along the lines of this

test("root lists 3 colors", function(){
  var c = App.__container__.lookup('component:foo-bar');
  ok(c.foo.blah);
});

If you feel guilty about using the container during testing (which you shouldn't) you can create a helper to avoid having to fix it all over the place when/if an api changes in the future.

Ember.Test.registerHelper('containerLookup',
  function(app, look) {
    return app.__container__.lookup(look);
  }
);

Make sure you define this before

App.injectTestHelpers();

and then your test would look like

test("root lists 3 colors", function(){
  var c = containerLookup('component:foo-bar');
  ok(c.foo.blah);
});
