How to populate helm-source by regexp

Question

I am working on adding some functionality to phpunit.el such as selecting from a list of functions found in the current buffer (populated in Helm).

The issue is that I can't get Helm to be populated, even though I can find all the matches and when I dump out the list into the mini-buffer it shows ("test1" "test2" "functionA" "functionB") which is expected.

My code can be found here: https://github.com/eric-hansen/phpunit.el/blob/minor-mode/phpunit.el#L169-190

I've also checked out the multi-term question that was asked on here but didn't help me very much.

I ran into this problem myself when I was writing a similar function. The problem is that your generating function isn't getting called in the right buffer. (I can't remember which buffer it's actually getting called in--maybe the Helm buffer itself?)

Anyway, the fix is to wrap the generating function in with-helm-current-buffer, like this:

(defun phpunit-helm-get-all-test-candidates ()
  ""
  (with-helm-current-buffer
    (let ((test-functions '())) 
      (save-excursion
        (beginning-of-buffer)
        (while (search-forward-regexp php-beginning-of-defun-regexp nil t)
          (add-to-list 'test-functions
                       (format "%S" (match-string-no-properties 1)))))
      (message "test-functions found ZOMG: %s" test-functions)
      test-functions)))

Does it work if you remove the quote for the source?
