def isDraw(self, board):

this method is not a valid assertion for a draw. it returns True when the board is completely filled, regardless if a player wins.

the correct check should be something like this:

    def isDraw(self):
        if "-" not in self.board and not self.isWin():
            return True
        else:
            return False
