-We did a lot of work in laying the foundation of our app in the last step, so now we'll do
-something simple, and add full text search. We will also write an end-to-end test, because a good
-end-to-end test is a good friend. It stays with your app, keeps an eye on it, and quickly detects
-regressions.
-
-__`app/index.html`:__
-
-...
- Fulltext Search:
-
-
-
- {{phone.name}}
-
{{phone.snippet}}
-
-
-...
-
-__`test/e2e/scenarios.js`:__
-
-/* jasmine-like end2end tests go here */
-describe('PhoneCat App', function() {
-
- describe('Phone list view', function() {
-
- beforeEach(function() {
- browser().navigateTo('../../app/index.html');
- });
-
-
- it('should filter the phone list as user types into the search box', function() {
- expect(repeater('.phones li').count()).toBe(3);
-
- input('query').enter('nexus');
- expect(repeater('.phones li').count()).toBe(1);
-
- input('query').enter('motorola');
- expect(repeater('.phones li').count()).toBe(2);
- });
- });
-});

-## Discussion:
-
-We continued using the same controller that we set up in Step 2, but we added the following
-features to our app:
-
-* __Search Box:__ A standard HTML `` tag combined with angular's {@link
-angular.Array.filter $filter} utility (added to the repeater) lets a user type in search criteria
-and immediately see the effects of their search on the phone list. This new code demonstrates the
-following:
-
- * Two way Data-binding. This is one of the core features in angular. When the page loads,
- angular binds the name of the input box to a variable of the same name in the data model and
- keeps the two in sync.
-
-In this example, the data that you type into the input box (named __`query`__) is immediately
-available as a filter input in the list repeater (`phone in phones.$filter(`__`query`__`)`).
-Whenever the data model changes and this change causes the input to the repeater to change, the
-repeater will efficiently update the DOM to reflect the current state of the model.
-
- * Use of `$filter` in a template. The `$filter` function is one of several built-in {@link
- angular.Array angular functions} that augment JavaScript arrays during their evaluation as
- angular expressions. In {@link guide.expression angular expressions}, these array utilities are
- available as array methods. (They are prefixed with a $ to avoid naming collisions.)
-
- * `ng:repeat` automatically shrinks and grows the number of phones in the View, via DOM
- manipulation that is completely transparent to the developer. If you've written any DOM
- manipulation code, this should make you happy.
-
-* __CSS:__ We added in some minimal CSS to the file we set up in Step 0: `./css/app.css`.
-
-* __Testing:__ To run the end to end test, open http://localhost:8000/test/e2e/runner.html in
-your browser. This end-to-end test shows the following:
-
- * Proof that the search box and the repeater are correctly wired together.
-
- * How easy it is to write end-to-end tests. This is just a simple test, but the point here is
- to show how easy it is to set up a functional, readable, end-to-end test.
