This is the "paper-rock-scissors" game.

It's implemented in Python without third-party libraries. Only standard Python libraries were used:

• random: To get a random value for a computer's choice in the game.
• unittest: To test the application.

To run in Docker

The application is dockerised. To build a docker image run:

    docker build -t game .

To play a game run:

    docker run -ti game main.py

after building the docker image.

To run the tests, build a docker image and then execute:

    docker run game test/game_test.py

To run locally

The application can work without docker too, if it's more convenient for you. Just add the game directory to the PYTHONPATH env variable and run:

    python ./main.py

Then you can also run the tests in the same way:

    python test/game_test.py
