2. Setting up RSpec

As I mentioned in chapter 1, our contacts manager is currently
functioning . At least we think it’s functioning–our only proof of that
is we clicked through the links, made a few dummy accounts, and added
and edited data. Of course, this doesn’t scale as we add features. (I’ve
deployed apps with even less tests than that; I bet some of you have,
too.) Before we go any further toward adding new features to the
application, we need to stop what we’re doing and add an automated test
suite to it, using RSpec and a few helper gems to make it happen.
