+1 (and -1000 on any Makefile targets which run as sudo)

It doesn't hurt to have an extra target like test-depends, but it
should be enough to just have the test target depend on some other
target that's required for whatever technology the author is using.
For eg., if it was a python charm that needed some python packages:


.virtualenv:
    virtualenv .virtualenv
    .virtualenv/bin/pip install -r test_requirements.txt

test: .virtualenv
    ./virtualenv/bin/python ./unit-tests

Yep, you could make that DRYer, but it might be less readable.
