(python + selenium) 数据驱动(参数化)

读取txt文件中的数据来实现参数化
创建data.txt文件



baidu_readData.py#-*- coding:utf-8 -*-

from selenium import webdriver
import os,time

source = open("C:\Python27\example\data.txt","r")
values = source.readlines()
source.close()

driver = webdriver.Chrome()
driver.get("http://www.baidu.com")

for val in values:
driver.find_element_by_id("kw").clear()
driver.find_element_by_id("kw").send_keys(val)
driver.find_element_by_id("su").click()
time.sleep(3)

driver.quit()
登录参数化（读取txt文件）
按照上面的思路，对自动化脚本中用户名、密码进行参数化，通过Python文档我们发现读取文件的方式有：整个文件读取、逐行读取、固定字节读取。并没有找到一次读取两条数据的好方法。

创建data.txt文件



login_douban_by_txt.py#-*- coding:utf-8 -*-

from selenium import webdriver
import os,time

source = open("C:\Python27\example\data.txt","r")
values = source.readlines()
source.close()

for val in values:
if "username" in val:
un = val.split('=')[1:]
elif "password" in val:
pw = val.split('=')[1:]

print un,pw
driver = webdriver.Chrome()
driver.get("http://www.douban.com")
driver.find_element_by_name("form_email").clear()
driver.find_element_by_name("form_email").send_keys(un)
time.sleep(3)
driver.find_element_by_name("form_password").clear()
driver.find_element_by_name("form_password").send_keys(pw)
time.sleep(3)
driver.find_element_by_class_name("bn-submit").click()
time.sleep(3)
driver.quit()
登录参数化（函数）
userinfo.pydef fun(un="15757119427",pw='mailu777333'):
print "successful read username and password!"
return un,pwlogin_douban_by_function.pyfrom selenium import webdriver
import hello_selenium,time

un,pw=hello_selenium.fun()

print un,pw

driver = webdriver.Chrome()
driver.get("http://www.douban.com")
driver.find_element_by_name("form_email").clear()
driver.find_element_by_name("form_email").send_keys(un)
time.sleep(3)
driver.find_element_by_name("form_password").clear()
driver.find_element_by_name("form_password").send_keys(pw)
time.sleep(3)
driver.find_element_by_class_name("bn-submit").click()
time.sleep(3)
driver.quit() 表单参数化(csv)
创建userinfo.csv文件



loop_read.py#-*- coding:utf-8 -*-

#导入csv包
import csv

#读取本地csv文件
my_file="C:\Python27\example\data.csv"
data=csv.reader(file(my_file,'rb'))

#循环输出每一行的内容
for user in data:
print user[0]
print user[1]
print user[2]
print user[3]运行结果：
