I'm currently starting to build a package the TDD way, and for that I'm using ert, following ert-runner opinions.

I would like to write a set of pending tests, to identify what I have I to test, before to implement the test.

Is it possible to write pending test in ert?

If so how? :)

Placing a call to ert-skip at the beginning of your test would be the solution I believe. If you'd like, you can pass the string "pending" to the function to better show why it was skipped.

(ert-deftest my-pending-test ()
  (ert-skip "pending")
  (should (dostuff)))
  • Hey @Jordon, this is working indeed, however when I run it with ert-runner the test is identified as Passing. (which is finally the same compared with no body, as I way doing until now). Do you know if there is a way the test is identified as neither failed neither passing? :) Commented May 15, 2015 at 9:32
  • maybe it's a bug in ert-runner?

It's not specifically for "pending", but marking the test as expected to fail seems like it would be what you want: http://www.gnu.org/software/emacs/manual/html_node/ert/Expected-Failures.html

add `:expected-result :failed' to the test definition:

 (ert-deftest future-bug ()
   "Test `time-forward' with negative arguments.
 Since this functionality isn't implemented, the test is known to fail."
   :expected-result :failed
   (time-forward -1))

ERT will still display a small `f' in the progress bar as a reminder that there is a known bug, and will count the test as failed, but it will be quiet about it otherwise.
