  @param {Object} cfg Configuration object
  
  <pre>
  * action - test to be measured and executed. Default action is a refresh of the root templates
  * repeat - number of test repetitions - Default 5
  * silent - By default the test will display an info window. If silent TRUE, don't show it
  * incremental - By default the test will remove one selector at a time. Setting this value to true the test will remove all selectors and measure the impact of only one selector
  </pre>
  
  @param {Callback} callback Function called when all tests are done
  @example
  Action function has the following signature:
  
  action = function(testName, iteration, callback)
  
  Where
  <pre>
  * testName is the name of the current test
  * iteration is the iteration number indicating how many times the action was executed
  * callback is the function to be called when the action is done. This allows for asynchronous tests
  </pre>
