Performance Count Cop does not work #69
Description
Expected behavior
I am expecting offenses for
[1, 2, 3].select { |e| e > 2 }.size
[1, 2, 3].reject { |e| e > 2 }.size
[1, 2, 3].select { |e| e > 2 }.length
[1, 2, 3].reject { |e| e > 2 }.length
as seen in https://github.com/rubocop-hq/rubocop-performance/blob/master/lib/rubocop/cop/performance/count.rb
Actual behavior
I don't receive offenses
Steps to reproduce the problem
file foobar.rb with
# frozen_string_literal: true
def foobar
[1, 2, 3].select { |e| e > 2 }.size
[1, 2, 3].reject { |e| e > 2 }.size
[1, 2, 3].select { |e| e > 2 }.length
[1, 2, 3].reject { |e| e > 2 }.length
end
executing rubocop performance via rubocop --require rubocop-performance foobar.rb
