我正在创建可以由 pytest 执行的测试函数。我已经创建了一个并且通过了，但我需要测试我创建的每个函数，但不知道如何做到这一点。
我尝试过使用断言，但我所有的测试都失败了。我看过有关理解测试的视频，但我似乎无法掌握如何使用它。这是我到目前为止所拥有的：
import random
players = []
MAX_PLAYERS = 8
def main():
print("Are you ready to Left, Right, Center Game!")
print("----------------------------------------------------")
print("Let's play!!!")
print("----------------------------------------------------")
money = bet()
print("We are betting $"+str(money)+ " per person")
number_of_people = get_people()
number_of_people = int(number_of_people)
get_names(number_of_people)
print("All names have been entered, let's play")
run_game(players)
winners_money = money * number_of_people
print(f"You won, " + str(winners_money))
print("----------------------------------------------------")
def get_people():
while True:
try:
number_of_people = int(input("How many people are playing? (3-8) "))
if 3 <= number_of_people <= MAX_PLAYERS:
return number_of_people
except ValueError:
pass
def get_names(number_of_people):
for name in range(number_of_people):
name = input("Name: ").strip().title()
players.append({"name": name, "chips": 3})
def bet():
while True:
amount = input("How much would you like to bet? $")
if amount.isdigit():
amount = int(amount)
if amount > 0:
break
else:
print("Amount must be greater than 0.")
else:
print("Please enter a number. Number needs to be greater than 0")
return amount
def run_game(players):
chips = ["L", "R", "C", "🔴", "🔴", "🔴"]
while True:
for player in players:
print(f"\n{player['name']}'s turn\n")
if player["chips"] > 0:
number_of_rolls = min(player["chips"], 3)
rolls = []
for _ in range(number_of_rolls):
action = random.choice(chips)
if action == "L":
left_player = players[(players.index(player) - 1) % len(players)]
left_player["chips"] += 1
rolls.append("L")
elif action == "R":
right_player = players[(players.index(player) + 1) % len(players)]
right_player["chips"] += 1
rolls.append("R")
elif action == "C":
player["chips"] -= 0
rolls.append("C")
elif action == "🔴":
player["chips"] += 1
rolls.append("🔴")
player["chips"] -= 1
print(f"{player['name']} rolled: {', '.join(rolls)}")
else:
print(f"{player['name']} has no chips left. Skip turn.")
print("\nCurrent chip counts:")
for player in players:
print(f"{player['name']}: {player['chips']}")
print("----------------------------------------------------")
remaining_players = [player for player in players if player["chips"] > 0]
if len(remaining_players) == 1: # Only one player remaining
last_player = remaining_players[0]
if "🔴" in rolls: # Last player rolled dot, end the game
print()
print(f"{last_player['name']} rolled 🔴!!! The game is over.")
print(f"{last_player['name']} won!!! CONGRATS!!!!!!")
return
else:
print(f"{last_player['name']} has to roll 'dot' to end the game.")
continue
if __name__ == "__main__":
main()
from project import get_people, get_names, bet, run_game

您不应该将测试代码放入主代码中。让我们创建您的主文件如下。
import random
players = []
MAX_PLAYERS = 8
def main():
print("Are you ready to Left, Right, Center Game!")
print("----------------------------------------------------")
print("Let's play!!!")
print("----------------------------------------------------")
money = bet()
print("We are betting $"+str(money)+ " per person")
number_of_people = get_people()
number_of_people = int(number_of_people)
get_names(number_of_people)
print("All names have been entered, let's play")
run_game(players)
winners_money = money * number_of_people
print(f"You won, " + str(winners_money))
print("----------------------------------------------------")
def get_people():
while True:
try:
number_of_people = int(input("How many people are playing? (3-8) "))
if 3 <= number_of_people <= MAX_PLAYERS:
return number_of_people
except ValueError:
pass
def get_names(number_of_people):
for name in range(number_of_people):
name = input("Name: ").strip().title()
players.append({"name": name, "chips": 3})
def bet():
while True:
amount = input("How much would you like to bet? $")
if amount.isdigit():
amount = int(amount)
if amount > 0:
break
else:
print("Amount must be greater than 0.")
else:
print("Please enter a number. Number needs to be greater than 0")
return amount
def run_game(players):
chips = ["L", "R", "C", "🔴", "🔴", "🔴"]
while True:
for player in players:
print(f"\n{player['name']}'s turn\n")
if player["chips"] > 0:
number_of_rolls = min(player["chips"], 3)
rolls = []
for _ in range(number_of_rolls):
action = random.choice(chips)
if action == "L":
left_player = players[(players.index(player) - 1) % len(players)]
left_player["chips"] += 1
rolls.append("L")
elif action == "R":
right_player = players[(players.index(player) + 1) % len(players)]
right_player["chips"] += 1
rolls.append("R")
elif action == "C":
player["chips"] -= 0
rolls.append("C")
elif action == "🔴":
player["chips"] += 1
rolls.append("🔴")
player["chips"] -= 1
print(f"{player['name']} rolled: {', '.join(rolls)}")
else:
print(f"{player['name']} has no chips left. Skip turn.")
print("\nCurrent chip counts:")
for player in players:
print(f"{player['name']}: {player['chips']}")
print("----------------------------------------------------")
remaining_players = [player for player in players if player["chips"] > 0]
if len(remaining_players) == 1: # Only one player remaining
last_player = remaining_players[0]
if "🔴" in rolls: # Last player rolled dot, end the game
print()
print(f"{last_player['name']} rolled 🔴!!! The game is over.")
print(f"{last_player['name']} won!!! CONGRATS!!!!!!")
return
else:
print(f"{last_player['name']} has to roll 'dot' to end the game.")
continue
if __name__ == "__main__":
main()
然后，您需要按照pytest的要求创建另一个文件，将其命名为：test_my_game.py，在test_my_game.py中，您应该打开一个新进程并在其中运行您的game.py。您可以使用 lib pexpect 来派生一个子进程并与其通信。示例
import pexpect
child = pexpect.spawn("python3 <path to you game.py>")
child.expect ('Are you ready to Left, Right, Center Game!')
child.expect ('How much would you like to bet? $')
child.sendline("30")
最后进行测试
pytest test_my_game.py
