I think this discussion could probably do with fewer unsupported assertions about what is "usual" -- it's clear that experiences in different parts of the community vary widely. Speaking personally and anecdotally, I maintain 15 or so projects on PyPI, and every single one of them has at least three or four test-only dependencies; not just a test runner, but also testing utilities of one kind or another (e.g. the mock backport for Python 2). So my personal percentage of "packages with more than one test-only dependency" is not 0.1%, it's 100%. I don't have any idea what the real percentage is on PyPI, and wouldn't hazard a guess. I'm fairly sure you don't know either. Carl
