If you’re using rspec 3, you might run into the following error when you try to run a views spec with the
rake spec command:
1 2 3
If so, try two things: first, make sure that your spec has
require 'rails_helper', not
require 'spec_helper'. Additionally, make sure you specify
type: :view in the RSpec definition, e.g.
RSpec.describe 'view.html.erb', type: :view do.
