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:

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(....)
或
- 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。
