Include all Helpers for Testing

When your helpers use each other, or your view tests use many, it gets frustrating to include them by hand…
This will load all helpers from app/helpers dir and include them!
Happy, stress-free testing!

def include_helpers
  Dir.glob("#{RAILS_ROOT}/app/helpers/*_helper.rb").each do |file|
    helper = File.basename(file).sub('.rb','').camelcase.constantize
    include helper
  end
end

Your Controller/View/Helper test would look like this:

describe MoviesHelper do
  include_helpers
  ...
end

Getting all other helpers(e.g. from helpers/admin is more complicated, but surely possible…)
