title: Mock response data with serverless framework
body: <p>The docs give the following as a mock example:</p>
  
  <pre><code>functions:
    hello:
      handler: handler.hello
      events:
        - http:
            path: hello
            cors: true
            method: get
            integration: mock
            request:
              template:
                application/json: '{"statusCode": 200}'
            response:
              template: $input.path('$')
              statusCodes:
                201:
                  pattern: ''
  </code></pre>
  
  <p>This does create a mock response...except it's empty.</p>
  
  <p>How can I actually return data here?  I've tried adding <code>application/json: {...}</code> to <code>template</code>, but that doesn't work, I've tried adding a body under <code>statusCodes</code> but no luck there either.</p>
  
  <p>There doesn't seem to be any documentation on this...how can I return an actual body?</p>
