""" Run tests from diplomacy.tests.network.test_real_game to test games in a real environment.
    Each test run a game and checks game messages and phases against an expected game data file.
    Current tested gama data files are JSON files located into folder diplomacy/tests/network:
        1.json
        2.json
        3.json
    Need a local diplomacy server running. You must specify this server port using parameter --port=<server_port>.
    To run all tests:
        python -m diplomacy.tests.network.run_real_game --port=<server_port>
    To run a specific test (e.g. 2.json, or 2.json and 1.json):
        python -m diplomacy.tests.network.run_real_game --cases=20 --port=<server_port>
        python -m diplomacy.tests.network.run_real_game --cases=15,20 --port=<server_port>
