Trying RSepc for the first time with no luck

I finally want to add real testing to my Rails app and using various tutorials to learn. This github page - https://gist.github.com/kyletcarlson/6234923 - has some great boiler plate examples and I think I'm following it correctly but can't get it to work. I get the following error:

// ♥ rspec

Here is my User model:

class Employee < ApplicationRecord
    has_many :employee_projects
    has_many :projects, through: :employee_projects
end

and here is my rspec test:

require 'rails_helper'


RSpec.describe Employee, type: :model do
  describe 'ActiveRecord Association tests' do 
    it { expect(employee).to have_many(:employee_projects) }  
    it { expect(employee).to have_many(:projects).through(:employee_projects)}
  end 
end

and my Gem file looks like this:

Do I have rspec installed correctly? Not sure about what I'm doing wrong.
