2-fer is short for two for one. One for you and one for me.
"One for X, one for me."
When X is a name or "you".
If the given name is "Alice", the result should be "One for Alice, one for me." If no name is given, the result should be "One for you, one for me."
For installation and learning resources, refer to the Ruby resources page.
For running the tests provided, you will need the Minitest gem. Open a terminal window and run the following command to install minitest:
gem install minitest
If you would like color output, you can
require 'minitest/pride' in
the test file, or note the alternative instruction, below, for running
the test file.
Run the tests from the exercise directory using the following command:
To include color from the command line:
ruby -r minitest/pride two_fer_test.rb
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
require 'minitest/autorun' require_relative 'two_fer' # Common test data version: 1.2.0 4fc1acb class TwoFerTest < Minitest::Test def test_no_name_given # skip assert_equal "One for you, one for me.", TwoFer.two_fer end def test_a_name_given skip assert_equal "One for Alice, one for me.", TwoFer.two_fer("Alice") end def test_another_name_given skip assert_equal "One for Bob, one for me.", TwoFer.two_fer("Bob") end end
# frozen_string_literal: true class TwoFer def self.two_fer(name = 'you') 'One for %s, one for me.' % name end end
A huge amount can be learned from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
