结合这两种方法对代码做二次封装,可以提升脚本性能

例:

#coding:utf-8

#封装元素方法
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import *
from selenium.webdriver.support import expected_conditions as EC
import time
#加入下面三行代码 在python2中就不会出现乱码问题
import sys
reload(sys)
sys.setdefaultencoding('utf-8') class Base():
def __init__(self,driver):
self.driver=driver #查找元素
def find_element(self,locator):#locator参数是定位方式,如("id", "kw"),把两个参数合并为一个,*号是把两个参数分开传值
element=WebDriverWait(self.driver,20,0.5).until(lambda x:x.find_element(*locator))
print(element)
return element
#判断元素文本
def is_text_in_element(self,locator,text):
try:
WebDriverWait(self.driver,20,0.5).until(EC.text_to_be_present_in_element(locator,text))
return True
except TimeoutException:
return False
#判断元素的value属性
def is_value_element(self,locator,text):
try:
WebDriverWait(self.driver,20,0.5).until(EC.text_to_be_present_in_element_value(locator,text))
return True
except:
return False #判断元素是否被定位到
def is_exists(self,locator):
try:
WebDriverWait(self.driver,20,0.5).until(EC.presence_of_element_located(locator))#不需要*,这里跟*locator不是一个参数
return True
except:
return False
#判断元素是否已经不存在,不存在了返回True,还存在就返回False
def element_is_disappeared(self,locator,timeout=30):
is_disappeared=WebDriverWait(self.driver,timeout,1,(ElementNotVisibleException)).until_not(lambda x:x.find_element(*locator).is_displayed())
print is_disappeared #封装一个send_keys
def send_keys(self,locator,text):
self.find_element(locator).send_keys(text) #封装一个click
def click(self,locator):
self.find_element(locator).click()
# #封装一个text
# def get_text(self,locator,text):
# return self.find_element(locator,text).text #运行主函数
if __name__=='__main__':
driver=webdriver.Chrome()
driver.get("https://www.baidu.com")
#实例化
base=Base(driver)
#定位输入框
input_loc=("id","kw")
#通过实例调用find_element来发送
base.send_keys(input_loc,"selenium")
#点击按钮
