python Web应用程序测试selenium库使用用法详解

from selenium import webdriver
#webdriver可以认为是浏览器的驱动器，要驱动浏览器必须用到webdriver，支持多种浏览器，这里以Chrome为例
browser = webdriver.Chrome()

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('https://www.taobao.com')
print(browser.page_source)#browser.page_source是获取网页的全部html
browser.close()

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('https://www.taobao.com')
input_first = browser.find_element_by_id('q')
input_second = browser.find_element_by_css_selector('#q')
input_third = browser.find_element_by_xpath('//*[@id="q"]')
print(input_first,input_second,input_third)
browser.close()

from selenium import webdriver
from selenium.webdriver.common.by import By
browser = webdriver.Chrome()
browser.get('https://www.taobao.com')
input_first = browser.find_element(BY.ID,'q')#第一个参数传入名称，第二个传入具体的参数
print(input_first)
browser.close()

input_first = browser.find_elements_by_id('q')

from selenium import webdriver
import time
browser = webdriver.Chrome()
browser.get('https://www.taobao.com')
input = browser.find_element_by_id('q')#找到搜索框
input.send_keys('iPhone')#传送入关键词
time.sleep(5)
input.clear()#清空搜索框
input.send_keys('男士内裤')
button = browser.find_element_by_class_name('btn-search')#找到搜索按钮
button.click()

from selenium import webdriver
from selenium.webdriver import ActionChains#引入动作链
browser = webdriver.Chrome()

browser.get(url)
browser.switch_to.frame('iframeResult')#切换到iframeResult框架
source = browser.find_element_by_css_selector('#draggable')#找到被拖拽对象
target = browser.find_element_by_css_selector('#droppable')#找到目标
actions = ActionChains(browser)#声明actions对象
actions.drag_and_drop(source, target)
actions.perform()#执行动作

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('https://www.zhihu.com/explore')
browser.execute_script('window.scrollTo(0, document.body.scrollHeight)')

browser = webdriver.Chrome()
url = 'https://www.zhihu.com/explore'
browser.get(url)
input = browser.find_element_by_class_name('zu-top-add-question')
print(input.id)#获取id
print(input.location)#获取位置
print(input.tag_name)#获取标签名
print(input.size)#获取大小
browser.close()
