Don't meet her at all. If she asks why, tell her honestly, that you respect her right not to take a test, so she must respect your right not to dare risk meeting her as long as Covid 19 is around.
If she truly is a friend, she should then reconsider her actions, or agree only "to meet" on Face-time or Zoom.
Good advice. Fair to her as you are respecting her right and expressing your own right!
