Hi @kots14, thanks for opening your first PR into Matplotlib!

A bit of an odd one in that despite sounding like it is doing things with dates, with these inputs actually just amounts to plot (and is a discouraged method because of that)... But it works and I guess no harm in testing it like this.

(For reference, it only does anything beyond plot if xdate=True or ydate=True are passed, at which point it sets the units of the axis)

Should I include additional tests to accommodate this in the same test? Please suggest.

I'd say this is fine for this test file. If anything, I think I'd move towards actually deprecating this method, as it's been soft-deprecated (i.e. discouraged in the docstring, but not warning at runtime) since 3.5.

The date plotting parts of this method are already tested in test_axes.py (as full image comparison tests, so even more rigorous than we are wanting here initially).
