See line 1732 of your patch for #7981 ;-) - `kwds.setdefault('filename',
sage.misc.misc.tmp_filename() + '.png') `
> Also, what exactly should the test do? How do I verify that images from
`show` and `save` are the same? It seems like a waste of time on tests if
it is only checked that these commands don't raise an exception - they
were working before as well, just not as they should.
Sadly, we can't do that yet. (Matplotlib apparently does do this with
Nose, but we don't have the capability yet.) Partly this could be useful
for the future day when we CAN check things like this...
But for now the point is that at least someone can visually verify that
there is a different min than $y=-5$ if they care to look. We want to
document that we have done something about the particular one.
Alternately, you could try to ask a release manager to close this as a
duplicate of #7981. Personally, I think it would be worth adding an
example to the save documentation that one can choose to either put the
commands in `.save(foo=bar)` or to pass it one from `plot(f,foo=bar)`;
that could be useful for a complete newbie to the code to see, so that
they don't have to follow code around.
