Data-driven test instances

There are many types of data-driven forms:

1. How variables are defined

2. How to define arrays and dictionaries

3. How to read files (txt\csv\xml)

1. parameterization by defining variable mode

public.py

Class Login ():
    def user_login (self,driver,username,password):
        driver.find_element_by_xpath ("//input[@ Name= ' email '). Clear ()
        Driver.find_element_by_xpath ("//input[@name = ' email ']"). Send_keys (username)
        Driver.find_element_by_name ("password"). Clear ()
        driver.find_element_by_name ("password"). Send_keys (password )
        driver.find_element_by_id ("Dologin"). Click ()
    def user_logout (self,driver):
        driver.find_element_by _link_text ("Exit"). Click ()
        driver.quit ()

mailtest.py

From selenium import webdriver from public
import Login
class Logintest ():
    def __init__ (self):
        Self.driver=webdriver. Firefox ()
        self.driver.implicitly_wait (self.driver.get) (
        "http://www.126.com")
    def Test_admin_ Login (self):
        username= ' admin '
        password= ' 123 '
        Login (). User_login (Self.driver,username,password)
        Self.driver.quit ()
    def test_guest_login (self):
        username= ' guest '
        password= ' 321 '
        login ( ). User_login (Self.driver,username,password)
        self.driver.quit ()
logintest (). Test_admin_login ()
Logintest (). Test_guest_login ()

2. Parameterization by means of array definition

From selenium import webdriver
search_text=[' python ', ' Chinese ', ' text '] for
text in Search_text:
    driver= Webdriver. Firefox ()
    driver.implicitly_wait (driver.get) (
    "http://www.baidu.com")
    driver.find_element_by_id ( ' kw '). Send_keys (text)
    driver.find_element_by_id (' su '). Click ()
    driver.quit ()

3, through the way to read the TXT file parameterized

Python provides the following methods for reading a TXT file:

Read (): Read the entire file

ReadLine (): reads a row of data

ReadLines (): reads all rows of data

User_info.txt

Zhangsan,123

lisi,456

wangwu,789

user_info.py

User_file=open (' User_info.txt ', ' R ')
Lines=user_file.readlines ()
user_file.close () for line in
lines:
     username=line.split (', ') [0]
     password=line.split (', ') [1]
     print (Username,password)

4, by reading the CSV file method for parameterization

csv_read.py

Import CSV
date=csv.reader (open (' Info.csv ', ' R '))
#循环输出每一行信息 for
user in date:
     print (user)
# Loop out the second column of data for the
user in date:
     print (user[1])

5. parameterization by reading XML files

Info.xml

<?xml version= "1.0" encoding= "Utf-8"?>

<info>

<base>

<platform>Windows</platform>

<browser>Firefox</browser>

<url>http://www.baidu.com</url>

<login username= "admin" password= "123456"/>

<login username= "Guest" password= "654321"/>

</base>

<test>

<province> Beijing </province>

<province> Guangdong </province>

<city> Shenzhen </city>

<city> Zhuhai </city>

<province> Zhejiang </province>

<city> Hangzhou </city>

</test>

</info>

From xml.dom import minidom
#打开xml文档
dom=minidom.parse (' info.xml ')
#得到文档元素对象
root= Dom.documentelement
Print (root.nodename)
print (root.nodevalue) print (
root.nodetype)
print (root . Element_node)
#获得任意标签名
tagname=root.getelementsbytagname (' browser ')
print (tagname[0].tagname)
#获得标签的属性值
tagname=root.getelementsbytagname (' login ')
username=tagname[0].getattribute (" Username ")
print (username)
Password=tagname[0].getattribute (" password ")
print (password)
Username=tagname[1].getattribute ("username")
print (username)
Password=tagname[1].getattribute (" Password ")
print (password)
#获得标签对之间的数据
provinces=root.getelementsbytagname (' Province ')
Citys=root.getelementsbytagname (' city ')
p2=provinces[1].firstchild.data
C1=citys[0].firstchild.data
c2=citys[1].firstchild.data
Print (p2)
print (c1)
print (C2)
