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

Hi David,
I agree it would be preferable to note that not all tests are run when
dependencies are missing, although I don't think it is extremely
important. I think some version of the above would be worthwhile if it
could be done in a file-wide manner (as are the current dependency
checks) and wouldn't require duplicating the dependency check or
changing every test form individually. Perhaps a file-local-variable
could be used to expect failures for every form defined in the file?
Cheers -- Eric

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!" (org-babel-execute-src-block))))))
#+end_src
#+begin_quote
ELISP> (macroexpand '(org-test-with-dependencies (("ESS" (featurep 'ess))) (ert-deftest foo () t)))
(progn
(ert-deftest foo nil :expected-result :failed
(error "Missing dependency: %s" "ESS")
t))
ELISP>
#end_quote
If this is acceptable I'd push it and start to adjust the test
definitions.

Nice macro,
The only downside I see is the requirement to wrap every single deftest
form which (to me) is too much overhead for too little payoff. How
about the following which will register a failing test for each file of
tests not loaded due to missing dependencies.

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.
