If your driver doesn't have post (Poltergeist doesn't, for example), you can do this:

session = ActionDispatch::Integration::Session.new(Rails.application)
response = session.post("/mypath", my_params: "go_here")

But note that this request happens in a new session, so you will have to go through the response object to assert on it.

As has been stated elsewhere, in a Capybara test you typically want to do POSTs by submitting a form just like the user would. I used the above to test what happens to the user if a POST happens in another session (via WebSockets), so a form wouldn't cut it.
