如何使用pygame和类似pygame.MOUSEBUTTONDOWN的成员编写脚本的单元测试？

Question

我正在用python创建一个Connect 4的简单游戏，并将pygame用于GUI，但是我似乎找不到一种为同一单元编写单元测试的方法

这是我的python脚本script

对于类似方法，

def play(self, board, players, is_valid_move, make_move, is_winning_move):
        """Method to play the game in GUI using pygame

        Note:
            When playing with AI a mouse click is required to trigger AI move

        Args:
            board (numpy.ndarray): Game board
            players (list): List of players
            is_valid_move (function): Move validator
            make_move (function): Makes move
            is_winning_move (function): Ckeck for winning move"""
        turn = random.randint(0, len(players) - 1)
        while True:
            self.draw(board)
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    return None

                if event.type == pygame.MOUSEMOTION:
                    self.draw_black_rec()
                    self.draw_player_coin(players[turn].p_id, event)
                pygame.display.update()

                if event.type == pygame.MOUSEBUTTONDOWN:
                    self.draw_black_rec()
                    if players[turn].name == "AI":
                        col = players[turn].get_move()
                    if is_valid_move(col):
                        row = make_move(col, players[turn].p_id)
                    turn = (turn + 1) % len(players)

我希望编写一个测试上述功能的单元测试，如果我不能仅对一部分方法进行整个方法的测试，它也将起作用。
