Use Test Driven Development (TDD) to create a collection of Ruby classes that would provide the foundation for creating a scrabble game. Don't actually build an interactive game (yet)!

From the project root, you should be able to execute all of your specs by running rake. Each Ruby class should be in its own file in lib/, and the entire project should be in a module called Scrabble. You will need to research using require, require_relative, include and/or extend to tell Ruby how to work with classes in multiple files.

We will use minitest for this project. This is the same test framework that we've used for the Weekend Warrior exercises. However, unlike Weekend Warrior, we will write our own tests using minitest specs format. Your spec descriptions should be meaningful and organized into describe blocks that reflect your intent on how to use the code.

Do not move onto a new tier of requirements until the minimum requirements of the previous tier are complete and your specs are green across the board. Use TDD to drive your development and document your edge cases.

Utilize good pair programming practices. Refer back to the articles from the Agile Alliance and the Agile Institute for best practices. Switch driver and navigator roles often. When there is uncertainity or confusion, step away from the keyboard and discuss, plan, and document on paper or whiteboard before continuing.

1. You'll be working with an assigned pair. High-five your pair.

2. Choose one person to fork the project repo.

3. Add the other person in the pair to the forked repo as a collaborator.

4. Add the second individual as a collaborator to the forked repo.

5. Both individuals will clone the forked repo: $ git clone [YOUR FORKED REPO URL]

6. Both individuals cd into the dir create:d $ cd scrabble

7. Both individuals install needed tools via Terminal:

   $ gem install simplecov`
   $ gem install minitest-reporters

First, come up with a "plan of action" for how you want to work as a pair. Discuss your learning style, how you prefer to recive feedback, and one team communication skill you want to improve with this experience. Second, review the requirements for Wave 1 and come up with a "plan of action" for your implementation.

• Create a Scrabble module at the project root.
• Create a Scrabble::Scoring class which contains some sort of data structure to store the individual letter scores listed below.
• Create a Spec file which corresponds to your Scrabble::Scoring class. This spec should contain one red test as a starting point (this test can be modified as your get further through the requirements).
• Be able to execute your one test using rake from the project root.

Create a Scrabble::Scoring class with a minimum of 8 specs. The class should have the following class methods:

• self.score(word): returns the total score value for the given word. The word is input as a string (case insensitive). The chart in the baseline requirements shows the point value for a given letter.
  • A seven letter word means that a player used all the tiles. Seven letter words receive a 50 point bonus.
• self.highest_score_from(array_of_words): returns the word in the array with the highest score. In the case of tie, use these tiebreaking rules:
  • It’s better to use fewer tiles, in the case of a tie, prefer the work with the fewest letters.
  • There is a bonus for words that are seven letters. If the top score is tied between multiple words and one used all seven letters, choose the one with seven letters over the one with fewer tiles.
  • If the there are multiple words that are the same score and same length, pick the first one in the supplied list.

Create a Scrabble::Player class with a minimum of 11 specs. The only required paramter for instances of the class is the player's name. Instances of the class should repond to the following messages:

• #name: returns the value of the @name instance variable
• #plays: returns an Array of the words played by the player
• #play(word): Adds the input word to the plays Array
  • Returns false if player has already won
  • Returns the score of the word
• #total_score: Returns the sum of scores of played words
• #won?: If the player has over 100 points, returns true, otherwise returns false
• #highest_scoring_word: Returns the highest scoring played word
• #highest_word_score: Returns the highest_scoring_word score

Create a Scrabble::TileBag class with a minimum of 5 specs. It should have the following class and instance methods:

• #initialize Called when you use TileBag.new, sets up an instance with a collection of default tiles
• #draw_tiles(num) returns num number of random tiles, removes the tiles from the default set.
• #tiles_remaining returns the number of tiles remaining in the bag

Create specs for (minimum 2) and add to the Player class the following instance methods:

• #tiles a collection of letters that the player can play (max 7)
• #draw_tiles(tile_bag) fills tiles array until it has 7 letters from the given tile bag

• Create a Scrabble::Dictionary class that includes a method (class or instance) for searching a list of words to determine if a given word is valid (minimum of 5 specs).
• Create a Scrabble::Board class (minimum of 15 specs) that has a matrix (array of arrays) of tile places. Check if a word can be played on a given tile place in a certain direction (up/down or left/right).
