pytest 用 @pytest.mark.usefixtures("fixtureName")或@pytest.fixture(scope="function", autouse=True)装饰，实现类似setup和TearDown的功能

import pytest

@pytest.fixture(scope="class")
def class_auto():
    print("")
    print("class-begin")
    yield
    print("class-end")

 7     @pytest.fixture(scope="function", autouse=True)
 8     def funcion_auto(self):
 9         print("begin")
10         yield
11         print("end")

13     def test_case1(self):
14         print("test_case1:")
15         assert 0 == 0
16 
17     def test_case2(self):
18         print("test_case2:")
19         assert 0 == 0
