Because otherwise it's run as a fake root user and will fail on the
tests requiring real root permissions.

Yes, I need to run the tests in a supported and predictable environment.

It can but it's safer to run the tests in a clean environment otherwise
they can fail after switching branches or rebases and then one may waste
time on looking at the errors. This part doesn't consume much running
time in comparison with some other parts so why not to have it there.

I see. Why does tests-storage not depend on this target? E.g.
.PHONY: tests-storage
tests-storage: tox tests-storage-setup tests-storage-run
.PHONY: tests-storage-run
tests-storage-run:
tox -e "storage"
.PHONY: tests-storage-setup
tests-storage-setup:
python3 tests/storage/userstorage.py setup
But perhaps it is better the way it is because `make storage' requires
root access.

Not all tests there are marked as requiring root privileges (and they
pass without them).

It is needed to skip tests in common/systemctl_test.py that require
systemd. Perhaps we should use a different mechanism to disable them
there.
Other than that there is no difference between having this variable or
not when running without root privileges.

These are the tests where TRAVIS_CI=1 is needed.
But these are not storage tests. Do storage tests pass for you?
I always get the following error:
=====================================================================================

Any idea what could be wrong?
And in storage/qemuimg_test.py, the whole test suite always crashes on a
timeout in convert_to_qcow2, hiding the previous failures:
storage/qemuimg_test.py
