setup_teardown的使用场景

from appium import webdriver 
import pytest 

class Test_ABC(object):

	def setup_class(self):
		desired_caps = {}
		desired_caps['platformName'] = 'Android'
		desired_caps['platformVersion'] = '7.1'
		desired_caps['devicesName'] = '192.168.50.101:5555'
		desired_caps['appPackage'] = 'com.android.settings'
		desired_caps['appActivity'] = '.Settings'

		#声明driver对象
		self.driver = webdriver.Remote('http:127.0.0.1:21503/wd/hub', desired_caps)
	
	def teardown_class(self):
		self.driver.close_app()
		self.driver.quit()

	def test_a(self):
		self.driver.find_element_by_xpath("//*[contains(@text, 'WLA')]").click()
		#业务逻辑
