If you don't want to raise an exception, you could try something like (untested):

declare

    DBMS_OUTPUT.PUT_LINE('Test failed, I don''want the rest of the script'
      || ' to be executed.');

    goto end_proc;
  END IF;

  -- A bunch of great code here

  <>
  null;  -- this could be a commit or other lines of code
end;

Some people hate any GOTO statements as they can lead to spaghetti code if abused, but in simple situations like this (again, assuming you don't want to raise an exception) they work well imo.
