title: AngularJS: Mock request for multiple requests
body: <p>In an application I'm writing, we possibly fire more than 1 request (based on some preconditions) upon doing certain actions in the UI. I'm trying to write this in a test, but I'm finding a hard time trying to mock the request: if the request gets fired more than once, I each time get: </p>
  
  <pre><code>Error: Unexpected request: PUT my/test/url
      No more request expected 
  </code></pre>
  
  <p>Is there any way to have the mocked httpbackend respond to a request multiple times? (kind of like you could state in a Mockito verify how many times the action should be done on the mock)</p>
