Scrabble

Work on the sample exercise defined below for 30 minutes.

As you work, you may:

• Ask questions of your facilitator
• Reference external public resources (ie: Google, Ruby API, etc)
• Use the tooling most comfortable to you (Editor/IDE, testing framework, support tools like Guard, etc)

As you work, you should not:

• Copy code snippets other than those present in this description
• Seek live support from individuals other than your facilitator

Setup

$ git clone https://github.com/turingschool/scrabble
$ cd scrabble
$ bundle

Running Specs/Tests

Starter files for both MiniTest and RSpec are provided.

To run the RSpec specs:

bundle exec rake spec

To run the MiniTest tests:

bundle exec rake test

Sample Exercise: Word Scoring

Let’s use test-driven development to build pieces of a Scrabble-like game.

Create functionality to score words based on the following letter values:

Letter	Value
A, E, I, O, U, L, N, R, S, T	1
D, G	2
B, C, M, P	3
F, H, V, W, Y	4
K	5
J, X	8
Q, Z	10

{
  "A"=>1, "B"=>3, "C"=>3, "D"=>2,
    "E"=>1, "F"=>4, "G"=>2, "H"=>4,
    "I"=>1, "J"=>8, "K"=>5, "L"=>1,
    "M"=>3, "N"=>1, "O"=>1, "P"=>3,
    "Q"=>10, "R"=>1, "S"=>1, "T"=>1,
    "U"=>1, "V"=>4, "W"=>4, "X"=>8,
    "Y"=>4, "Z"=>10

}

Create your solution:

• using Test-Driven Development with MiniTest or RSpec
• insensitive to case
• such that an empty word or nil scores 0
• using this interaction model:

> game = Scrabble.new
=> ...
> game.score("hello")
=> 8
> game.score("")
=> 0
> game.score(nil)
=> 0
