Ruby – Error when trying to run rspec Failure/Error: require ‘test’ LoadError: cannot load such file — test

I am trying to run RSpec for Ruby on Rails. I am running Rails 5.0 I have installed the gem, have established a spec folder with some tests.

I run following command on console

$ rspec --init
create   spec/spec_helper.rb
create   .rspec

I create file called 'test.rb'.

class Test
end

I create file called 'zombie_spec.rb'.

require 'spec_helper'
require 'test'

describe Test do
    it " Name Is Bapu." do
        # test = test.new
        # test.name.should == 'bapu'
    end
end 

Then after I run this command.

rspec spec/lib/zombie_spec.rb

It shows error ⬇

An error occurred while loading ./spec/lib/zombie_spec.rb.
Failure/Error: require 'test'

LoadError:
  cannot load such file -- test
# ./spec/lib/zombie_spec.rb:2:in `require'
# ./spec/lib/zombie_spec.rb:2:in `<top (required)>'
No examples found.


Finished in 0.00026 seconds (files took 0.40148 seconds to load)
0 examples, 0 failures, 1 error occurred outside of examples

How do I resolve this so that I can start running tests?
