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:

________________________________________ ERROR collecting test_Person.py _________________________________________

有人可以解释和/或帮助我理解该怎么做吗？这是我的代码:

人.py 人类(对象):

    def __init__(self, first, last, sex):

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

print (person1.formalName())

print (person2.getSex())
print (person2.getLastName())

测试人员.py

    import pytest
    import Person


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

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

Answer 1

在测试程序中，我相信你必须要么

• 在 Person 类前面加上模块名称:Person.Person(....)

或

• 将导入更改为“from Person import *”。在这种情况下，所有类都作为“本地”导入
