The complete method is as follows ：

fixture(scope='function', params=None, autouse=False, ids=None, name=None)

Parameter description ：

1. scope Parameters ： Scope of marking method . Yes 4 Optional values ：function（ Default , function ）、class（ class ）、module（ modular ）、package/session（ package ）

-function： Every function or method calls

import pytest

# fixture precondition  function Corresponding  setup  Each use case will execute scope='function'
#  Postcondition  autouse  The default is False  Manual call   Don't call it manually every time   Automatically call 

# fixture precondition   Postcondition   Shutdown system 
@pytest.fixture(scope='function', autouse=True)
