stack level too deep on #get in request specs

[mbajur]

Subject of the issue

I just installed rspec in the rails engine gem i maintain. All i did was adding rspec-rails as a dependency and run rails g rspec:install. I created the simplest request spec possible:

require 'rails_helper'

RSpec.describe 'Root request', type: :request do
  describe 'GET /' do
    it 'returns a successfull response' do
      get '/'
      expect(response).to be_success
    end
  end
end

However, running it raises :

Failure/Error: get '/'

     SystemStackError:
       stack level too deep

I'm sorry if that was solved anywhere but the error produced and keywors are so generic it's very hard to find anything even remotely similar to my issue.

Your environment

• Ruby version: 3.2.0
• rspec-core version: 3.13.2

Steps to reproduce

Clone this app and run bundle exec rspec

If you run rspec with --backtrace, will there be anything pointing at an infinite loop? Can you share?

Ok, it turned out it was happening because i had no root_to route defined, rails was serving a default root template and it somehow messed up the get. Using a real route fixed that for me.
