I am a Cask ( junkie which provides really
nice command line invocation of tests, supports multiple versions of
Emacs, and runs in a headless environment. I normally run it inside
M-x compile.

Testing, I use ert.el. The framework is nice, but the reporting can be
poor, and keeping tests independent is hard work (that's Emacs' fault
rather than ert, I feel). So if I may be excused the plug, I've written
assess ( which adds better reporting,
macros for keeping Emacs tests free of side-effects, and adds some nice
predicates (for roundtripping indentation, testing font-lock and so on).
Probably, assess will go into core for Emacs-26 as ert-assess.

ecukes and buttercup, I cannot really vouch for one way or the
other. The whole BDD doesn't entirely make sense to me.
