Error when migrating for MiniTest to RSpec - ruby-on-rails

Question

I'm trying to migrate my rails application to RSpec. But I'm getting the error uninitialized constant ActiveRecord::Relation when running the specs. It says it's on line 10 of application.rb which is Bundler.require(:default, Rails.env) if defined?(Bundler)
error message
An error occurred while loading rails_helper.

Answer 1

My guess is that the RAILS_ENV environment variable is set to something other than test when you run your rspec command. I've run into this before on some machines that have the RAILS_ENV environment variable explicitly set to development or something else entirely (which like others have mentioned will cause the issue you're seeing since the environment file is missing for that value).
In your rails_helper.rb file, try changing this line:
ENV['RAILS_ENV'] ||= 'test'
to this:
ENV['RAILS_ENV'] = 'test'
and see if your tests can run. If that is the case, you'll want to either find where you have RAILS_ENV manually set (typically in a shell configuration file) and remove it, or copy your config/environments/test.rb file to new one to match whatever it is RAILS_ENV is set to.

Answer 2

I had this problem when using Windows.
In order to run my Ruby on Rails app with Postgress and use PG gem, I had to set RUBY_DLL_PATH=<your-path-to-postgresql>/bin. Meaning that the RAILS_ENV environment variable is set to something other than test when you running rspec command.
The solution of #codenamev worked for me.

Answer 3

The problem was related to the order of the gems in the Gemfile. I had to comment out all of the gems and add them all back one by one while changing the order to fix any errors.
