Write a program that manages robot factory settings.
When robots come off the factory floor, they have no name.
The first time you boot them up, a random name is generated, such as RX837 or BC811.
Every once in a while we need to reset a robot to its factory settings, which means that their name gets wiped. The next time you ask, it gets a new name.
Random names means a risk of collisions. In some exercism language tracks there are tests to ensure that the same name is never used twice.
For installation and learning resources, refer to the exercism help 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 runnng
the test file.
In order to run the test, you can run the test file from the exercise
directory. For example, if the test suite is called
hello_world_test.rb, you can run the following command:
ruby hello_world_test.rb
To include color from the command line:
ruby -rminitest/pride hello_world_test.rb
The test files may have the execution bit set so you may also be able to run it like this:
./hello_world_test.rb
