# Real implimentations:
# =====================
#
# This isn't really testing anything but the point is, rather than 
# reading the module to use from config and fixing the module for 
# all tests here we inject the module in the function call and supply
# a default for normal operation. This is akin to dependency injection
# in OO. Not sure if this is a good idea but seems more flexible as
# different tests can pass in a different fake (if needed).

<!--
In the template just use the @view object and call it's methods to clean up
the presentation logic. Maybe think about adding a helper method called `view`
that just returns `@view` so we can remove the noise of the `@`.

<%= @view.users.each do |user| %>
