Why not run a test (rspec)?

Hello, please tell me why not run the test.
There are model cinema.rb
In the folder spec/models have created a file cinema_spec.rb there's this code
require "spec_helper"
RSpec.describe Cinema :type => :model do
 it "should do something" do
 (1+1).should == 2
end
end

Run the following command rspec spec and you get the error - undefined method `Cinema' for main:Object (NoMethodError).
Test is test but I can not understand why not start. Do the lesson
