I can't run a basic rspec test with haml and rails6

Question

I started a simple project with rails 6 and haml-rails and rspec and my basic tests are failing on a basic get :home pointing to a simple haml template - I don't really know if it's a haml-rails, haml or rspec problem.

the errors I got

# rspec spec/controllers/static_pages_controller_spec.rb

Failed examples:

rspec ./spec/controllers/static_pages_controller_spec.rb:7 # StaticPagesController GET #home returns http success

my test - get :home is line 8

# frozen_string_literal: true

require 'rails_helper'

RSpec.describe StaticPagesController, type: :controller do
  describe 'GET #home' do
    it 'returns http success' do
      get :home
      expect(response).to have_http_status(:success)
    end
  end
end

and my controller

class StaticPagesController < ApplicationController
  def home; end
end

routes.rb

Rails.application.routes.draw do
  root to: 'static_pages#home'
end

I tried to use haml-rails and haml from master branch which seems to have some rails6 fixes but the errors I got are the same errors:

gem 'haml', github: 'haml/haml', branch: 'master'
gem 'haml-rails', github: 'indirect/haml-rails', branch: 'master'

Any suggestions that I may try or maybe is there any easy way to rollback from rails-haml to erb ?

Answer 1

I updated rspec and now it passes - it seems that rspec is not ready for rails 6
