python selenium-4自动化测试模型
1.线性测试
特点：每一个脚本都是完整且独立的，可以单独执行。
缺点：用例的开发与维护成本很高
2.模块化驱动测试
特点：把重复的操作独立成公共模块，提高测试用例的可维护性
示例：将搜索封装到func中，其他文件直接导入使用即可
func.py
class Func():
def search(self,driver):
driver.find_element_by_xpath("//input[@id='kw' and @class='s_ipt']").send_keys("hello")
driver.find_element_by_xpath("//input[@value='百度一下' and @id='su']").click()
result_text = driver.find_element_by_xpath("//span[@class='nums_text']").text
assert "百度为您找到相关结果约" in result_text
action.py
import sys
from selenium import webdriver;
from time import sleep
from testcase import func
path = sys.path[0].replace("testcase", "") + "driver/geckodriver"
driver = webdriver.Firefox(executable_path=path)
driver.implicitly_wait(5)
driver.get("http://www.baidu.com")
print("打开百度")
func.Func().search(driver)
#等同于
#s=func.Func()
#s.search(driver)
sleep(3)
driver.quit()
print("退出")
3.数据驱动测试
3.1参数化搜索关键字
func.py
from time import sleep
class Func():
def search(self,driver,word):
driver.find_element_by_xpath("//input[@id='kw' and @class='s_ipt']").clear()
driver.find_element_by_xpath("//input[@id='kw' and @class='s_ipt']").send_keys(word)
driver.find_element_by_xpath("//input[@value='百度一下' and @id='su']").click()
result_text = driver.find_element_by_xpath("//span[@class='nums_text']").text
assert "百度为您找到相关结果约" in result_text
sleep(1)
action.py
import sys
from selenium import webdriver;
from testcase import func
path = sys.path[0].replace("testcase", "") + "driver/geckodriver"
driver = webdriver.Firefox(executable_path=path)
driver.implicitly_wait(5)
driver.get("http://www.baidu.com")
print("打开百度")
func.Func().search(driver,"hello")
func.Func().search(driver,"world")
driver.quit()
print("退出")
3.2读取txt文件
read()：读取整个文件
readline()：读取一行数据
readlins()：读取所有行的数据
word.txt

selenium,阮一峰
action.py
import sys
from selenium import webdriver;
from testcase import func
path = sys.path[0].replace("testcase", "") + "driver/geckodriver"
driver = webdriver.Firefox(executable_path=path)
driver.implicitly_wait(5)
driver.get("http://www.baidu.com")
print("打开百度")
file = open("word.txt","r")
lines = file.readlines()
file.close()
for i in lines:
searchWord = i.split(',')[0]
func.Func().search(driver,searchWord)
driver.quit()
print("退出")
3.3读取csv文件
word.csv
#读取csv文件
import csv
data = csv.reader(open("word.csv","r"))
for user in data:
print(user,len(user),len(user[0]))
aciton.py
```#python
import csv
import sys
from selenium import webdriver;
from testcase import func
path = sys.path[0].replace("testcase", "") + "driver/geckodriver"
driver = webdriver.Firefox(executable_path=path)
driver.implicitly_wait(5)
driver.get("http://www.baidu.com")
print("打开百度")
data = csv.reader(open("word.csv",'r'))
for row in data:
if len(row[0])==0:
pass
else:
func.Func().search(driver,row[0])
func.Func().search(driver,row[1])
driver.quit()
print("退出")
## 3.4读取Excel文件

```#python
import xlrd
#打开表格
file = xlrd.open_workbook("word.xlsx")
#获取所有sheet,sheet_names()表名
print(file.sheet_names())
#根据sheet索引或名称获取shell内容
sheet1=file.sheet_by_index(0)
sheet2=file.sheet_by_name("工作表 1 - word")
#获取sheet表格的行数和列数
sheet2_row= sheet2.nrows
sheet2_col= sheet2.ncols
print(sheet2.name,sheet2_row,sheet2_col)
#获取每一行的数据
for i in range(sheet2_row):
print("",sheet2.row_values(i))
#获取每一列的数据
for i in range(sheet2_col):
print(sheet2.col_values(i))
# #获取单元格的数据
print(sheet2.cell(2,1).value,sheet2.cell(2,0).value)
#循环打印非空值
for i in range(sheet2_row):
for j in range(sheet2_col):
if len(sheet2.cell(i,j).value) != 0:
print(sheet2.cell(i,j).value)
import xlrd
import sys
from selenium import webdriver;
from testcase import func
path = sys.path[0].replace("testcase", "") + "driver/geckodriver"
driver = webdriver.Firefox(executable_path=path)
driver.implicitly_wait(5)
driver.get("http://www.baidu.com")
print("打开百度")
data = xlrd.open_workbook("word.xlsx")
sheet2_data=data.sheet_by_index(1)
sheet2_rows=sheet2_data.nrows
sheet2_col=sheet2_data.ncols
for i in range(sheet2_rows):
for j in range(sheet2_col):
if i > 0:
text=sheet2_data.cell(i,j).value
if len(text) > 0:
func.Func().search(driver,text)
driver.quit()
print("退出")
3.5读取xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!--注意：第一行如果直接键入会报错。输入<?xml，然后直接使用tab键生成第一行，删除多余内容即可-->
