# view to see whats happening

require 'rails_helper'

RSpec.describe UsersController do
  before(:each) do
    @ref = create(:user)
  end
  describe '#create' do
    it 'sets a referral code' do
      post :create, params: create_user_params(@ref.referral_code)
      expect(User.first.referral_code).to be_present
    end

    it 'adds a point to the referrer' do
      post :create, params: create_user_params(@ref.referral_code)
      @ref.reload
      expect(@ref.points).to eq 1
    end
  end
end

I noticed 2 things:

1. CreatesPoints#create_point doesn't save the user after incrementing points. Could that be the cause?
2. Both @ref = create(:user) and the newly-created referral User may have an empty referral_code. If that's the case, User.find_by(referral_code: …) could be returning a different user than the referrer.
