  <p>Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of
applications that use the <a href="api/ng/service/$http">$http service</a>.</p>
<p><em>Note</em>: For fake http backend implementation suitable for unit testing please see
<a href="api/ngMock/service/$httpBackend">unit-testing $httpBackend mock</a>.</p>
<p>This implementation can be used to respond with static or dynamic responses via the <code>when</code> api
and its shortcuts (<code>whenGET</code>, <code>whenPOST</code>, etc) and optionally pass through requests to the
real $httpBackend for specific requests (e.g. to interact with certain remote apis or to fetch
templates from a webserver).</p>
<p>As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
is being developed with the real backend api replaced with a mock, it is often desirable for
certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
templates or static files from the webserver). To configure the backend with this behavior
use the <code>passThrough</code> request handler of <code>when</code> instead of <code>respond</code>.</p>
<p>Additionally, we don&#39;t want to manually have to flush mocked out requests like we do during unit
testing. For this reason the e2e $httpBackend flushes mocked out requests
automatically, closely simulating the behavior of the XMLHttpRequest object.</p>
<p>To setup the application to run with this http backend, you have to create a module that depends
on the <code>ngMockE2E</code> and your application modules and defines the fake backend:</p>
<pre><code class="lang-js">myAppDev = angular.module(&#39;myAppDev&#39;, [&#39;myApp&#39;, &#39;ngMockE2E&#39;]);
myAppDev.run(function($httpBackend) {
  phones = [{name: &#39;phone1&#39;}, {name: &#39;phone2&#39;}];

// returns the current list of phones
  $httpBackend.whenGET(&#39;/phones&#39;).respond(phones);

// adds a new phone to the phones array
  $httpBackend.whenPOST(&#39;/phones&#39;).respond(function(method, url, data) {
    var phone = angular.fromJson(data);
    phones.push(phone);
    return [200, phone, {}];
  });
  $httpBackend.whenGET(/^\/templates\//).passThrough();
  //...
});
</code></pre>
<p>Afterwards, bootstrap your app with this new module.</p>
