Bob is a lackadaisical teenager. In conversation, his responses are very limited.
Bob answers 'Sure.' if you ask him a question.
He answers 'Whoa, chill out!' if you yell at him.
He says 'Fine. Be that way!' if you address him without actually saying anything.
He answers 'Whatever.' to anything else.
Run the test file, and fix each of the errors in turn. When you get the first test to pass, go to the first pending or skipped test, and make that pass as well. When all of the tests are passing, feel free to submit.
Remember that passing code is just the first step. The goal is to work towards a solution that is as readable and expressive as you can make it.
Please make your solution as general as possible. Good code doesn't just pass the test suite, it works with any input that fits the specification.
Have fun!
The tests use the Minitest testing framework. To install it run the command:
gem install minitest
Run the tests with the ruby command:
ruby bob_test.rb
If you have never used Minitest, check out Intro to TDD tutorial from Jumpstart Lab.
