Mocking Time:

hello.rb

def print
    time = Time.now
    return time.strftime("%d%m%Y%H%M%S")
end

spec.rb

require 'minitest/autorun'
require 'minitest/mock'

it "should set the date to the current date" do
        old_time = Time.new(2019,11,11, 23, 30, 0)
        Time.stub(:now, old_time) do
            string_formatted_time = print
            string_formatted_time.must_equal "11112019233000"
        end
end
