在PythonV- 3.8中使用PyTest运行测试用例时出现“ Empty Suite”错误

如何解决在PythonV- 3.8中使用PyTest运行测试用例时出现“ Empty Suite”错误

下面是conftest.py和test_1.py文件的代码。知道为什么我会收到错误“ Empty Suite”。

1. conftest.py

   import pytest
   
   
   @pytest.fixture()
   def setup():
       print("hi")
       yield
       print("end")
   

2. test_1.py

   import pytest
   
   
   @pytest.mark.usefixtures("setup")
   class Abc:
       def test_demo(self):
           print("hello")
   
       def test_demo1(self):
           print("Hey")
   

运行test_1.py后出现以下消息：
