pytest错误（pytest和TDD新手）

Question

我在测试实例变量的长度时遇到了一个问题。我经常会遇到这样的错误：

________________________________________ ERROR collecting test_Person.py _________________________________________
test_Person.py:7: in <module>
    person1 = Person("Tara", "Manderson", "F")
E   TypeError: 'module' object is not callable

gender is:
M
last name is:

first name is:
Christopher
Mr. Christopher Murray is:

Mr. Christopher Murray

有人能解释和/或帮助我理解该怎么做吗？这是我的密码：

你知道吗个人.py 班级人员（对象）：

试验_个人.py你知道吗

    import pytest
    import Person


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

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

Answer 1

在测试项目中，我相信你必须

• 在Person类前面加上模块名：人。人（…..）

或者

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

Answer 2

作为jcoppensmentioned，您需要修复导入。但是你的测试还有几个问题。你知道吗

你的测试应该是：

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

注意getSex()-如果没有括号，则表示方法的长度，而不是返回的结果。你知道吗

作为一般提示，当您开始测试时，请使用print语句确保您正在测试您认为正在测试的内容。e、 g.打印出person1，将person1.getSex()赋给一个变量，并在断言它之前打印出来。你知道吗

而且在我看来，您的测试函数并不需要@pytest.fixture修饰符，因此可以删除它。你知道吗
