Overview

This fakes all page elements when used with the null driver. It’s a dirty way to avoid modeling all of what a driver talks to.

#send_keys(string) ⇒ Object

@@string is a class variable because this framework creates new instances of each element every time it accesses them. This is good behavior by default because pages could change underneath us. For text fields in the null browser, though, we want to preserve the values across calls, letting us write and then read.
