Practicing with accompanist

I'm starting to do more solo work with piano.  The woman who has accompanied
me is very good has limited experience accompanying violin - basically, I'm
it.

>From those of you who have done this a lot, do you have any tips about how
to get the most out of practice sessions?

One question: how to "teach" the phrasing I use in a piece.  Solos are not
strict tempo.  Do you generally play a piece through once in its entirety so
the pianist can get a feel for the phrasing, or is this useful?

Any ideas are appreciated.

TIA,

Karl Perry
