ert tests and dependencies.

ert tests and dependencies.

[Fabian Ezequiel Gallina]

I'm planning to add tests for the python.el shell integration, but for
these to run successfully a python executable must exist in the
system.

So the question is, what's the preferred way to define these kind of
tests that depend on other executables than Emacs?

I'm thinking on something like this:

(ert-deftest python-shell-test ()
  (if (not (executable-find "python"))
      (message "skipping python-shell-test...")
    (should ...))

But perhaps this has been discussed or there's a standard way already.

For vc-bzr, I used:

(ert-deftest vc-bzr-test-bug9726 ()
  "Test for http://debbugs.gnu.org/9726 ."
  :expected-result (if (executable-find vc-bzr-program) :passed :failed)
  (should (executable-find vc-bzr-program))
  ...)

A proper way to skip tests would be nicer.

That's good enough for me, thanks!

Although I agree it would be nice to have a way to skip tests.
