Pytest 从父类继承对象

Question

我试图从我的测试类中的父类继承对象，但是当我这样做时，我得到了这个：

============================= test session starts ==============================
collecting ... collected 0 items

============================== 1 warning in 0.00s ==============================

Process finished with exit code 5

Empty suite

Exit code 5位置：未No tests were collected

我的代码如下所示：

# parent.py

class Parent:

    def __init__(self):
        self.object_one = 'ABC {}'
        self.object_two = False
        self.object_three = 123

    def my_method_one(self, my_str):
        print(self.object_one.format(my_str))

    def my_method_two(self, is_true):
        assert is_true == self.object_two

    def my_method_three(self, my_num):
        assert my_num < self.object_three



# child.py

from functions.parent import Parent

class TestChild(Parent):

    def test_method_one(self):
        self.my_method_one('is my default string')

    def test_method_two(self):
        self.my_method_two(False)

    def test_method_three(self):
        self.my_method_three(10)

当我运行TestChild(Parent)类时，我收到了Empty suite消息。

如果需要更多上下文或用法没有意义，我会根据需要更新问题。
