pytest 错误(pytest 和 TDD 新手)

pytest error (newbie to pytest and TDD)

我在尝试测试实例变量的长度时遇到问题。我不断收到此错误:

有人可以解释 and/or 帮助我理解该怎么做吗?这是我的代码:

Person.py class 人物(对象):

    def __init__(self, first, last, sex):
        try:
            self.first = str(first)
            self.last = str(last)
            if (((sex=="M") or (sex=="F")) and (len(sex)==1)):
                self.sex = sex
            elif ((not(sex=="M") or not(sex=="F")) or not(len(sex)==1)):
                raise UserWarning("Invalid Input! Use \"M\" for male or \"F\" for female.")
            else:
                raise TypeError("Not a valid gender! Use \"M\" for male or \"F\" for female.")
            self.civilstat= "S"
        except TypeError:
            print ("invalid arguement error")


    def getSex(self):
        print ("gender is:")
        return self.sex


    def getLastName(self):

        elif ((not(self.civilstat=="M") or not(self.civilstat=="F")) or not(len(self.civilstat)==1)):
            print ("not a valid status")

        else:
            print ("not a valid status")


    def setMarried(self, newLastName):
            if (self.sex == "F") and (newLastName == ""):
                raise ValueError("Please, what is her new last name? Re-enter her maiden name if she didn't change it.")

            elif (self.sex == "F") and (newLastName != ""):

                self.last= newLastName
                self.civilstat= "M"

            elif (self.sex == "M") and (newLastName == ""):
                    self.civilstat= "M"

            elif (self.sex == "M") and (newLastName != ""):
                raise ValueError("Well, that's strange here. Please, leave his last name blank like \" \".")


    def setDivorced(self):
        if (self.civilstat != "M"):
            raise UserWarning("Wait! That person is not married.")
        elif (self.civilstat == "M"):
            self.civilstat= "D"

                self.title= "Mrs."

            else:
                self.title= "Ms."

        return (self.title + " " + self.first + " " + self.last)


person1 = Person("Tara", "Manderson", "F")
person2 = Person("Christopher", "Murray", "M")
print (person1.getSex())
print (person1.getLastName())
print (person1.getFirstName())
print (person1.getCivilStatus())
print (person1.formalName())

print (person2.getSex())
print (person2.getLastName())
print (person2.getFirstName())
print (person2.getCivilStatus())
print (person2.formalName())

test_Person.py

    import pytest
    import Person


    person1 = Person("Tara", "Manderson", "F")

    @pytest.fixture
    def test_getSex():
            assert len(person1.getSex) == 1

在测试程序中,我相信你要么

  • 在 Person class 前加上模块名称:Person.Person(....)

  • 将导入更改为 'from Person import *'。在这种情况下,所有 classes 都被导入为 'local'

作为 jcoppens ,您将需要修复您的导入。但是你的测试还有几个问题。

你的测试应该是:

def test_getSex():
        assert len(person1.getSex()) == 1

注意 getSex() - 如果您没有括号,那么您断言的是方法的长度,而不是结果 returns。

作为一般提示,当您开始测试时,使用打印语句来确保您正在测试您认为正在测试的内容。例如打印出 person1,将 person1.getSex() 分配给一个变量并打印出来,然后再断言它。

而且在我看来,您的测试函数不需要 @pytest.fixture 装饰器,因此可以将其删除。
