Cop idea: Replace be matchers with be_between matcher

[ydakuka]

Actual behavior

I have the following spec:

# frozen_string_literal: true

require 'rails_helper'

RSpec.describe ApplicationHelper do
  specify do
    expect(foo).to be >= 2
    expect(foo).to be <= 10
  end

  specify do
    expect(foo).to be <= 10
    expect(foo).to be >= 2
  end

  specify do
    expect(foo).to be > 1
    expect(foo).to be < 11
  end

  specify do
    expect(foo).to be < 11
    expect(foo).to be > 1
  end

  def foo
    2
  end
end

I run rubocop and don't get any offences:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop spec/helpers/application_helper_spec.rb 
Inspecting 1 file
.

1 file inspected, no offenses detected

Expected behavior

# frozen_string_literal: true

require 'rails_helper'

RSpec.describe ApplicationHelper do
  specify do
    expect(foo).to be_between(2, 10)
  end

  specify do
    expect(foo).to be_between(1, 11).exclusive
  end

  def foo
    2
  end
end
