如何在单元测试中访问类属性

class Person:
    def __init__(self, name):
        self.name = name

# 单元测试中访问类属性
def test_person_name():
    person = Person("John")
    assert person.name == "John"

class Person:
    def __init__(self, name):
        self._name = name

    def get_name(self):
        return self._name

    def set_name(self, name):
        self._name = name

# 单元测试中访问类属性
def test_person_name():
    person = Person("John")
    assert person.get_name() == "John"

class Person:
    def __init__(self, name):
        self.name = name

# 单元测试中访问类属性
def test_person_name():
    person = Person("John")
    assert getattr(person, "name") == "John"
