Org-mode Testing

• To run the tests interactively
• To run the tests in batch mode

The following instructions describe how to get started using the Org-mode test framework.

To run the tests interactively

1. Install the jump.el testing dependency which is included as a git submodule in the org-mode repository. To do so run the following git submodule commands from inside the base of the Org-mode directory (or just execute the following code block).

     cd ..
     git submodule init
     git submodule update

2. Load the org-test.el file

     (load-file "org-test.el")

3. The org-test-jump command is now bound to M-C-j in all emacs-lisp files. Call this command from any file in the lisp/ directory of the org-mode repository to jump to the related test file in the testing/ directory. Call this functions with a prefix argument, and the corresponding test file will be stubbed out if it doesn't already exist.

4. Ingest the library-of-babel.org file since some tests require this.

     (org-babel-lob-ingest "../contrib/babel/library-of-babel.org")

5. Review the ERT documentation
6. A number of org-mode-specific functions and macros are provided in org-test.el see the ;;; Functions for Writing Tests subsection of that file. Some of these functions make use of example org-mode files located in the examples/ directory.

7. Functions for loading and running the Org-mode tests are provided in the ;;; Load and Run Tests subsection, the most important of which are

   • org-test-load which loads the entire Org-mode test suite
   • org-test-current-defun which runs all tests for the current function around point (should be called from inside of an Org-mode elisp file)
   • org-test-run-all-tests which runs the entire Org-mode test suite
   • also note that the ert command can also be used to run tests

8. Load and run all tests

     (load-file "org-test.el")
     (org-babel-lob-ingest "../contrib/babel/library-of-babel.org")
     (org-test-load)
     (org-test-run-all-tests)

To run the tests in batch mode

First tangle this file out to your desktop.

  ;; add to the load path
  (add-to-list 'load-path (concat org-dir "/lisp/"))
  (add-to-list 'load-path (concat org-dir "/lisp/testing/"))
  (add-to-list 'load-path (concat org-dir "/lisp/testing/ert/"))
  
  ;; load Org-mode
  (require 'org)
  
  ;; setup the ID locations used in tests
  (require 'org-id)
  (org-id-update-id-locations
   (list (concat org-dir "/testing/examples/babel.org")
         (concat org-dir "/testing/examples/ob-C-test.org")
         (concat org-dir "/testing/examples/normal.org")
         (concat org-dir "/testing/examples/ob-awk-test.org")
         (concat org-dir "/testing/examples/ob-fortran-test.org")
         (concat org-dir "/testing/examples/ob-maxima-test.org")
         (concat org-dir "/testing/examples/link-in-heading.org")
         (concat org-dir "/testing/examples/links.org")))
  
  ;; ensure that the latest Org-mode is loaded
  (org-reload)
  
  ;; load the test suite
  (load-file (concat org-dir "/testing/org-test.el"))
  
  ;; configure Babel
  (org-babel-lob-ingest (concat org-dir "/contrib/babel/library-of-babel.org"))
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((emacs-lisp . t)
     (sh . t)))
  (setq org-confirm-babel-evaluate nil)
  
  ;; run the test suite
  (org-test-run-all-tests)
  
  ;; print the results
  (with-current-buffer "*ert*"
    (print (buffer-string)))

Then run the test suite with the following command which could use any version of Emacs.

  emacs --batch -Q -l ~/Desktop/run-org-tests.el
