Solution

`Two-fer` or `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:

``````ruby two_fer_test.rb
``````

To include color from the command line:

``````ruby -r minitest/pride two_fer_test.rb
``````
