I think that it is not too bad if DISPLAY is not set.

  (1) In such a case you cannot run an X application properly so you
  cant run the tests anyway.  well, technically you could by passing
  -display but seldom do folks do it.

    $ unset DISPLAY 
    $ display # an X11 app
    display: Unable to connect to X server () [Function not implemented].  

  (2) Even if you ssh to a remote host and enable X11 forwarding the
  DISPLAY variable is automatically set.

  (3) I dont know why one would want to unset DISPLAY. :)
