Python3 Selenium自动化web测试 ==> 第十一节 WebDriver高级应用 -- 显示等待 + 二次封装

学习目的：

---

掌握显示等待

掌握二次封装

正式步骤：

---

step1:显示等待的代码示例

# -*-  coding:utf-8 -*-
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
import time
import os

dr = webdriver.Chrome()
url = 'http://renren.com/'
dr.get(url)
# dr 表示打卡浏览器
# 30 表示超时总时长 30s
# 1 表示循环查询时间，默认时间间隔0.5s
# lambda x : x.find_element_by_xpath('//*[@id="email"]') 默认的官方格式，照旧
x = WebDriverWait(dr,30,1).until(lambda x : x.find_element_by_xpath('//*[@id="email"]'))
y = WebDriverWait(dr,30,1).until(lambda x : x.find_element_by_xpath('//*[@id="password"]'))
z = WebDriverWait(dr,30,1).until(lambda x : x.find_element_by_xpath('//*[@id="login"]'))
x.send_keys('[e-mail]')
y.send_keys('*******')
z.click()

step2: 二次封装

# -*-  coding:utf-8 -*-
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
import time
import os

class xianshidengdai():

    def __init__(self,driver):
        self.driver = driver
        self.timeout = 30
        self.t = 0.5

    def findelement(self,locator):
        element = WebDriverWait(self.driver,self.timeout,self.t).until(lambda x : x.find_element(*locator))
        return element

if __name__ == "__main__":
    driver = webdriver.Chrome()
    driver.get('http://renren.com')
    test = xianshidengdai(driver)
    loc1 = (By.XPATH ,'//*[@id="email"]')
    test.findelement(loc1).send_keys('***')
    driver.close()
