• the provided client should work with your server (running on port 8080)
• use akka-http and its routing DSL (https://doc.akka.io/docs/akka-http/current/scala/http/introduction.html#routing-dsl-for-http-servers)

Create Scala app from template.

• User can input “0”, “1”, “2” and play a game of Rock (0) Paper (1) Scissors (2).
• Create a Game object with a def play(): Unit method which asks for user input and prints the outcome of the game, including the two moves (user’s move and computer’s move)
• The computer’s move is generate at random

• convert the user input to a valid Move data type
• use ADT (Algebraic Data Type, i.e. sealed case objects in Scala) encoding for enum
• use an Option to signal the parsing can fail
• refactor the implementation to work with the Move data type

Minor refactor

• using a “guard” to ensure x and y are equal in the Draw case
• using “0”, “1”, “2” still sucks

• Controller: routing logic (mostly wiro annotations and data model conversions)
• Service: application logic (the computation of the computer move)
• Repository: persistence logic (where the play result is stored in memory)

Use test tool Scalatest to provide a game logic unit test

• use enumero (https://buildo.github.io/retro/docs/enumero/introduction) to encode Move
• use indexedEnum from enumero, using String as index
• use CaseEnumSerialization to print to string and CaseEnumIndex to parse from index

• wiro lib integrated
