title: Cannot add @angular/testing npm package to Angular2 project
body: <p>I am trying to setup the Angular2 project with unit tests.
  I am using this manual: <a href="http://twofuckingdevelopers.com/2016/01/testing-angular-2-with-karma-and-jasmine/" rel="nofollow">http://twofuckingdevelopers.com/2016/01/testing-angular-2-with-karma-and-jasmine/</a>
  It is obviously outdated, because now default Angular2 npm package is @angular/*</p>
  
  <p>The stated example doesn't work, because angular2 package is different.
  So I am re-mapping everything to that @angular package.</p>
  
  <p>My package.json contains the following dependencies:</p>
  
  <pre><code>"dependencies": {
  "@angular/common": "^2.0.0-rc.5",
  "@angular/compiler": "^2.0.0-rc.5",
  "@angular/core": "^2.0.0-rc.5",
  "@angular/http": "^2.0.0-rc.5",
  "@angular/platform-browser": "^2.0.0-rc.5",
  "@angular/platform-browser-dynamic": "^2.0.0-rc.5",
  "@angular/router": "^3.0.0-rc.1",
  "@angular/router-deprecated": "^2.0.0-rc.2",
  "@angular/upgrade": "^2.0.0-rc.5",
  "es6-promise": "^3.2.1",
  "es6-shim": "^0.35.1",
  "reflect-metadata": "^0.1.2",
  "rxjs": "5.0.0-beta.6",
  "zone.js": "^0.6.17"
  },
  "devDependencies": {
  "@angular/testing": "^0.0.0-0",
  "concurrently": "^2.0.0",
  "eslint": "^3.3.1",
  "eslint-config-google": "^0.6.0",
  "eslint-config-standard": "^6.0.0",
  "eslint-plugin-promise": "^2.0.1",
  "eslint-plugin-standard": "^2.0.0",
  "jasmine-core": "2.4.1",
  "karma": "^1.2.0",

  "typings": "^1.0.4"
  }

  <p>I deleted all node_packages folder to start from clean slate.</p>
  
  <p>When running "npm install", I see the following output:</p>

  <p>What I should do to get it work?
  Or maybe you can suggest the tutorial that covers unit testing which works for most recent Angular2 version?</p>
