anchor.diff:  == Summary
   
   I hope you've enjoyed this quick-and-easy tutorial on testing Angular 2 applications. You can see the test coverage of your project by running
  -`npm run serve.coverage`. You'll notice that our new components and service could use some additional coverage. I'll leave that as a task
  -for the reader. Please send a pull request to https://github.com/mraible/angular2-tutorial[this project] if you're ambitious.

  If you run `npm test`, you'll get a failed build from a number of unused imports. Let's fix those by adding the first test of `getAll()`. You can see
  how the `MockBackend` is used to mock results and set the response.
  
  When you are testing code that returns either a Promise or an RxJS Observable, you can use the `fakeAsync` helper to test that code as if it were synchronous.
  Promises are be fulfilled and Observables are notified immediately after you call `tick()`.

  Running `npm test` should result in "10 tests completed". Add a couple more tests for filtering by search term and fetching by id.
