Splinter 快速介绍

官方网站:http://splinter.cobrateam.info/

官方介绍:

Splinter is an open source tool for testingweb applications using Python. It lets you automate browser actions, such asvisiting URLs and interacting with their items

特性:

1、可以模拟浏览器行为,访问指定的URL,并且可以指定不同的浏览器类型。比如firefox或者chrome等。不同的浏览器只要在本地安装对应的驱动,就可以在代码中通过名称指定来访问。
2、支持cookie操作,可以很方便的添加和删除cookie;
3、支持模拟鼠标的动作,比如滑动到某个按钮上,焦点离开某个按钮等等,对于带有动态提示的页面,如搜索引擎的关键字输入框的动态提示,可以非常方便的测试。
4、支持模拟键盘的输入操作,对input等控件的输入可以模拟用户的type过程。
5、支持直接运行js或者调用页面的js。
6、支持模拟上传文件。
7、对radio和checkbox有专门的api支持,非常方便;
8、支持快速的获取页面的元素或者判断是否存在文本,用于开发判断页面提示信息是否准确非常方便。
9、最重要的,splinter的API非常简单,配合官方的文档学习成本几乎是0,当然你得懂一些python语法。如果你比较了解js和css,你可能会像喜欢jquery一样喜欢它;

功能:

Splinter执行的时候会自动打开你指定的浏览器,访问指定的URL。
然后你所开发的模拟的任何行为,都会自动完成,你只需要坐在电脑面前,像看电影一样看着屏幕上各种动作自动完成然后收集结果即可。


举个例子,我们要回归登录功能,首先要开发如下模拟登录行为的脚本:

代码如下:


#!/usr/bin/py2
# -*- coding: utf-8 -*-
#encoding=utf-8

import sys, re
from splinter.browser import Browser 

CLOASE_AFTER_TEST = False
reload(sys)
sys.setdefaultencoding('utf8')
encoding = lambda x:x.encode('gbk') 

def testLogin(desc, username, password, result):
    output(desc)      
    browser.fill('TPL_username',username.decode('utf8'))
    browser.fill('TPL_password',password.decode('utf8'))
    browser.find_by_value('登录').first.click()
    checkresult(result) 

def output(x):
    print encoding(x) 

def resultMsg(x):
    if x == True:
        print 'pass'
    else:
        print '[X]not pass'

def checkresult(x):
    """  check result message, x : the error message u want  """
    resultMsg(browser.is_text_present(x)) 

__testUrl = 'http://waptest.taobao.com/login/login.htm?tpl_redirect_url=http%3A%2F%2Fm.taobao.com%2F' 

# chrome driver : http://code.google.com/p/selenium/wiki/ChromeDriver
browser = Browser()  # already support firefox
browser.visit(__testUrl)
output("测试页面:"+browser.title) 

try:
    # test login
    testLogin('测试未输入用户名','','','请输入会员名')
    testLogin('测试未输入密码','qd_test_001','','请输入密码')
    testLogin('测试帐户不存在','这是一个不存在的名字哦','xxxxxxx','该账户名不存在')
    testLogin('测试成功登录','qd_test_001','taobao1234','继续登录前操作') 

    # test find password
    output("测试[找回密码]链接")
    browser.visit(__testUrl)
    backPasswordLink = browser.find_link_by_text('取回密码')
    if 1 == len(backPasswordLink):
        backPasswordLink.first.click()
        ru = re.findall(re.compile(".*(reg/gp.htm).*", re.IGNORECASE), browser.url)
        if ru is not None:
            checkresult('找回密码')
        else:
            output("测试找回密码链接失败") 

except Exception,x:
    print x 

if CLOASE_AFTER_TEST:
    browser.quit()

Is the conversion speed fast when converting XML to PDF on mobile phone? Is the conversion speed fast when converting XML to PDF on mobile phone? Apr 02, 2025 pm 10:09 PM

The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.

What is the function of C language sum? What is the function of C language sum? Apr 03, 2025 pm 02:21 PM

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

Is there a mobile app that can convert XML into PDF? Is there a mobile app that can convert XML into PDF? Apr 02, 2025 pm 09:45 PM

There is no APP that can convert all XML files into PDFs because the XML structure is flexible and diverse. The core of XML to PDF is to convert the data structure into a page layout, which requires parsing XML and generating PDF. Common methods include parsing XML using Python libraries such as ElementTree and generating PDFs using ReportLab library. For complex XML, it may be necessary to use XSLT transformation structures. When optimizing performance, consider using multithreaded or multiprocesses and select the appropriate library.

It is not easy to convert XML to PDF directly on your phone, but it can be achieved with the help of cloud services. It is recommended to use a lightweight mobile app to upload XML files and receive generated PDFs, and convert them with cloud APIs. Cloud APIs use serverless computing services, and choosing the right platform is crucial. Complexity, error handling, security, and optimization strategies need to be considered when handling XML parsing and PDF generation. The entire process requires the front-end app and the back-end API to work together, and it requires some understanding of a variety of technologies.
