Running tests

Tests can be executed by make test or invoking emacs directly with the command-line below:

emacs -Q --batch -q \
      -L . \
      -l ob-hy.el \
      -l test-ob-hy.el \
      --eval "(progn \
                (setq org-confirm-babel-evaluate nil) \
                (org-babel-do-load-languages \
                  'org-babel-load-languages '((emacs-lisp . t) \
                                              (sh . t) \
                                              (org . t) \
                                              (hy . t))))" \
