Question

I get an error when i'm trying to launch rspec :

An error occurred while loading ./spec/factories_spec.rb.
Failure/Error:
  FactoryGirl.factories.map(&:name).each do |factory_name|
    describe "The #{factory_name} factory" do
      it 'is valid' do
        build(factory_name).should be_valid
      end
    end
  end

NameError:
  uninitialized constant FactoryGirl

and

Please comment if you need more informations

Answer 1

About the former error. You probably are using some modern version of FactoryGirl, and now it calls FactoryBot and uses FactoryBot constant. So use FactoryBot instead of FactoryGirl

About the latter one. Maybe you have your Cipher class defined multiple times in multiple places and that's why you're getting this error. Or maybe you're trying to call it different than OpenSSL::Cipher. Any details about Cipher class could clarify the situation
