application.rb

module Offmarket
  class Application < Rails::Application

    # don't generate RSpec tests for views and helpers
    config.generators do |g|
      g.test_framework :rspec, fixture: true
      g.fixture_replacement :factory_girl, dir: 'spec/factories'

      g.view_specs false
      g.helper_specs false
    end

Seems good, but I rather prefer not to generate tests/specs for everything. I prefer to do all the configuration myself. So I go like rails -T and start from there adding the test/spec framework and directory structure that I like.
