help with unit testing

[mpsn]

Hi, I have a class XMLtool where one of the functions is to output a parameter-passed dom document and then output to the browser screen, so basically:

 

function outputXML($domDocument) {

  if has attributes

    print cur nodes attributes

  for each child,

      if child is element node

          outputXML(cur node)

      else if child is text

          print text

  end for each

}

 

Please I am not sure what type of unit tests I can perform. I'd appreciate all the help!
