Hi all,
Currently tests with missing dependency are silently skipped -- it
might be worth changing this behavior to not skip them, but mark them
as expected to fail. You can do this in ERT by placing the
keyword :expected-result followed by either :passed or :failed before
the test's body.
Benefit of this is that the tests w/ missing dependencies will show up
in the ERT result page (with a small letter f) but (obviously) don't
count as failures.
The following macro is a first shot at a convenient way to define
tests with dependencies:
#+begin_src emacs-lisp
(defmacro org-test-deftest-with-dependency (dependency &rest body)
(let* ((docstring (if (stringp (third body)) (list (third body))))
(deftest (nthcdr (if docstring 3 2) body))
(dependency-p (eval dependency)))
`(ert-deftest ,@(append (list (first body) (second body)) docstring)
,@(if dependency-p
'(:expected-result :passed)
'(:expected-result :failed (error "Missing dependency")))
,@deftest)))
#+end_src
Here DEPENDENCY is a simple form that evaluates to non-nil if the
dependency is met. If marking the tests this way is the agreed way to
go we can extend the syntax of a dependency to an alist with a
human-readable description of the dependency as key and a list of
forms that all must eval to non-nil as value. E.g.
#+begin_src emacs-lisp
(defvar test-ob-R-dependencies
'(("R executable" (org-test-for-executable "R"))
("Package ESS" (featurep 'ess))))
#+end_src
And change the expander code to map through this alist and as soon one
dependency evals to nil sets a variable `dependency-missing' to the
respective dependency.
Any comments on this?
Best,
-- David

Perl's TAP* (http://testanything.org/) uses SKIP results for tests that should not be run because some prerequisite is not available, and TODO tests for those that are expected to fail (due to not being implemented, known breakage, etc). They can be reported separately if the harness wishes. It sounds like this is what is being proposed. Perhaps some prior art could be used. * I reference TAP because it is what I am familiar with, not because it is better or worse than alternatives.

I tried the approach with a file-local variable but it didn't work out: A macro can be expanded at any time, i.e. looks like there is no way to obtain a reference to the buffer where the macro is defined at expansion time. But finally came up with this one: #+begin_src emacs-lisp (defmacro org-test-with-dependencies (dependencies &rest body) "Mark `ert-deftest' forms in BODY with a expected result depending on DEPENDENCIES. DEPENDENCIES is an alist with a human-readable name of the dependency as key. The second element of each member should be a form that evaluates to a non-nil value if the dependency is met. All `ert-deftest' forms in BODY are marked as expected to pass if all dependencies are met. Otherwise the expected result is set to `:failed' and the test's bodies modified to signal an error with an error message indicating the first failing dependency." (macrolet ((define-dependencies () `(cond ,@(mapcar (lambda (dependency) `((not ,(second dependency)) ,(first dependency))) dependencies)))) (let ((missing-dependency (define-dependencies))) `(progn ,@(mapcar (lambda (sexp) (if (and (consp sexp) (eq (first sexp) 'ert-deftest)) (let* ((docstring (if (stringp (fourth sexp)) (list (fourth sexp)))) (deftest-body (nthcdr (if docstring 4 3) sexp))) `(,@(append (list (first sexp) (second sexp) (third sexp)) docstring) :expected-result ,@(if missing-dependency `(:failed (error "Missing dependency: %s" ,missing-dependency)) '(:passed)) ,@deftest-body)) sexp)) body))))) #+end_src You wrap it around ert-deftest forms, e.g. #+begin_src emacs-lisp (org-test-with-dependencies (("ESS" (featurep 'ess))) (ert-deftest test-ob-R/simple-session () (org-test-with-temp-text "#+begin_src R :session R\n paste(\"Yep!\")\n#+end_src\n" (should (string= "Yep!"

The macro operates not just on a single `ert-deftest' form, but all deftests in BODY. It kind-of works like a file local variable. The current solution does its job, too -- so there's no need to use this macro. Getting feedback about tests not run because of missing dependencies is all I every wanted.
