[Pkg-emacsen-addons] Bug#829170: dh_elpa_test: option to run tests inside dtach for tests that need a tty

[Sean Whitton]

Source: dh-elpa
Version: 0.0.21
Severity: wishlist

Some ERT (and possibly Buttercup) test suites need a tty to run.  That
is, they fail under `emacs -batch' while succeeding under `emacs -nw'.

src:evil-el works around this by launching the test suite inside dtach.
This method comes from src:notmuch.  src:evil-el checks the test exit
status but swallows the stdout; src:notmuch manages to display the
stdout (though note that src:notmuch doesn't use ERT or Buttercup).

It would be nice if the user could specify something like

    export DH_ELPA_TEST_TTY=yes

in their rules file and dh_elpa_test would take care of it for them.
