【问题描述】：

使用方法'setBaseTestProviders(..)'时，控制台会弹出错误。

我们正在使用 angular-2.0.0-rc.1。

测试（test/areas-list.component.spec.ts）如下：

import {setBaseTestProviders} from "@angular/core/testing";
import {ADDITIONAL_TEST_BROWSER_PROVIDERS, TEST_BROWSER_STATIC_PLATFORM_PROVIDERS} from '@angular/platform-browser/testing/browser_static';
import {BROWSER_APP_DYNAMIC_PROVIDERS} from '@angular/platform-browser-dynamic';

setBaseTestProviders([
    BROWSER_APP_DYNAMIC_PROVIDERS,
    ADDITIONAL_TEST_BROWSER_PROVIDERS,
], TEST_BROWSER_STATIC_PLATFORM_PROVIDERS);

describe('test test', () => {
   //Not really important
});

当我打开浏览器时，控制台显示以下错误：

zone.js:323 Error: Error: Cannot resolve all parameters for 'ViewUtils'(RootRenderer, undefined @Inject(Token AppId), SanitizationService). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'ViewUtils' is decorated with Injectable.

有人知道问题出在哪里吗？提前致谢！

【解决方案1】：

您是否尝试使用浏览器静态来实现任何特定情况？

这是基本配置：

import { setBaseTestProviders } from '@angular/core/testing';
import {
  TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS,
  TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
} from '@angular/platform-browser-dynamic/testing';

setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS, TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
