Several ways.  The easiest is to run the tests from the M-x compile
command and use the find next error command.

If you run them from within a shell in emacs (rather than M-x
compile), then you can use the following two functions and keybinding
to search for errors in the immediately preceeding command output in
the shell.

Note that find-errors searches backwards for a shell prompt.  If you
have an unusual shell prompt, this may require tweeking.

----------------------------------------------------------------------
(defun find-errors ()
  "Find the Errors in the current shell buffer."
  (interactive)
  (save-excursion 
    (re-search-backward "^[a-zA-Z0-9]+\\$")
    (set-mark (point))
    (re-search-backward "^[a-zA-Z0-9]+\\$")
    (find-errors-in-region)
    (next-error '(4)))
 )

(defun find-errors-in-region ()
  "Use highlighted errors as compile errors."
  (interactive)
  (copy-region-as-kill (region-beginning) (region-end))
  (goto-char (point-max))
  (let ((oldbuf (get-buffer "*shell errors*")))
    (if oldbuf (kill-buffer oldbuf)))
  (let ((outbuf (get-buffer-create "*shell errors*")) )
    (switch-to-buffer outbuf)
    (insert-string "\n\n\n\n")
    (yank)
    (setq compilation-last-buffer outbuf)
    (compilation-mode) ))

(global-set-key "\C-ce" 'find-errors)
----------------------------------------------------------------------

Emacs uses regular expressions to find and parse the "compile" output.
If it cannot find the test case errors, jsut add the appropriate REs
to the error list.
