1、结合unittest以及元素定位的8方法，编写具体的测试用例

from selenium import  webdriver
from selenium.webdriver.common.by import By
import time as t

'''id的定位'''
driver=webdriver.Chrome()
driver.get('http://www.baidu.com')
driver.find_element_by_id('kw').send_keys("Hellow World")
t.sleep(5)

'''name的定位'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_name('wd').send_keys("Hellow World")
# t.sleep(5)

'''class_name的定位'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_class_name('s_ipt').send_keys("Hellow World")
# t.sleep(5)

'''xpath的定位'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_xpath('//*[@id="kw"]').send_keys("Hellow World")
# t.sleep(5)

'''css定位'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_css_selector('#kw').send_keys("Hellow World")
# t.sleep(5)

'''LINK_TEXT'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_link_text('直播').click()
# t.sleep(5)

'''PARYIAL_LINK_TEXT'''
# driver=webdriver.Chrome()
# driver.get('http://www.baidu.com')
# driver.find_element_by_partial_link_text('播').click()
# t.sleep(5)

 

2、通过实际的案例来演示单个元素定位和多个元素的方式
