We can verify this with a Spock test:

given:

def engine = new GameEngineClient()

expect:

!engine.session

when:

def savedSession = engine.game_start()

then:

engine.session

engine.page == 'players'

engine.session.players.size() == 2

engine.session.players[0].playerClass == 'NextFreeSpacePlayer'

engine.session.players[1].playerClass == 'RandomPlayer'

when:

engine = new GameEngineClient()

savedSession = engine.select_players(

[

playerX: 'NextFreeSpacePlayer',

playerO: 'NextFreeSpacePlayer'

],

savedSession)

then:

engine.page == 'roundX'

when:

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'X'], savedSession)

then:

engine.page == 'roundO'

when:

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'O'], savedSession)

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'X'], savedSession)

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'O'], savedSession)

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'X'], savedSession)

engine = new GameEngineClient()

savedSession = engine.play_round([player: 'O'], savedSession)

then:

engine.page == 'roundX'
