First, a caveat, aside from any problems with "at":

	BE CAREFUL WHEN YOU NAME A SCRIPT test.  test IS A BUILTIN
	COMMAND IN THE MODERN sh AND ksh.  EXECUTING test WITHOUT A
	QUALIFYING PATH NAME WILL USUALLY EXECUTE THE SHELL'S BUILTIN
	test COMMAND OR /bin/test ON OLDER SHELLS.  ON OLDER SHELLS
	THIS WILL DEPEND ON HOW YOUR $PATH IS SET UP.  NAMING YOUR OWN
	SCRIPT test CAN ALSO CAUSE OTHER SHELL SCRIPTS TO BREAK BECAUSE
	THEY PROBABLY EXPECT DIFFERENT BEHAVIOR FROM test THAN WHAT YOU
	PROBABLY CODED!

Now, back to "at":

Are you sure the script is executed? What version of Unix are you on?
On System V, Release 3, "at" will not take commands from the command line.

When I try your example, I get:

	at: bad date specification

The usual way to do this would be:

	$ at now + 1 minute
	test xyz
	<control-d>	#or whatever your EOF char is

From the User's Ref Man:
          at and batch read commands from standard input to be
          executed at a later time.       ^^^^^^^^^^^^^^
