Lib/test/test_startfile.py

   1 # Ridiculously simple test of the os.startfile function for Windows.
   2 #
   3 # empty.vbs is an empty file (except for a comment), which does
   4 # nothing when run with cscript or wscript.
   5 #
   6 # A possible improvement would be to have empty.vbs do something that
   7 # we can detect here, to make sure that not only the os.startfile()
   8 # call succeeded, but also the the script actually has run.
