Maybe you (or Eduardo...) what you wrote in the cover:
There's one current caveat: it requires Python 3, as it's based on the
venv module.
To explain:
$ make check-acceptance
/usr/bin/python2: No module named venv

Hmm maybe we should print something like:
"You can now activate this virtual environment using:
source $(TESTS_VENV_DIR)/tests/venv/bin/activate"
