Meaningless import

[lovesegfault]

test_stream.py imports pytest on line 2, however it seems like there is no pytest, so should this import really be here?

It's not meaningless. Pytest automatically finds files containing tests and runs them. This is a bit of implicit magic that I don't like, but such is life.

actually @bemeurer I think you're right.
