Question

我有一个简单的BankAccount类程序，可以进行通常的存款，提款和结余。现在我想在测试中使用fixture，以便fixture创建对象实例，这样我就不必在测试函数中运行构造函数

class BankAccount:

    def __init__(self, name, ID, creation_date, amount):
        self.name = name
        self.ID = ID
        self.creation_date = creation_date
        self.amount = amount

    def deposit(self, amount):
        self.amount += amount
        print ("You Deposited: ", amount)
        print ("Your Balance is:", self.amount)

    def withdraw(self, amount):
        self.amount -= amount
        print ("You Withdrew", amount)
        print ("Your Balance is: ", self.amount)


    def view_balance(self):
        print ("Your Balance is: ", self.amount)

以下是我要执行的操作。它给我错误，对象BankAccount没有属性a_creation。我该如何完成

@pytest.fixture()
def a_creation():
    return ("whatever", "y7te", "12/1/2018", 2000)


def test_a_creation(a_creation):
    bk = BankAccount.a_creation
    test1 = bk.creation_date
    assert test1 == "12/1/2018"

我得到的错误是 TypeError： init （）缺少3个必需的位置参数：“ ID”，“ creation_date”和“ amount”

在类python中使用固定装置
