目前团队使用的自动化测试框架是robotframework+webdriver（IE）+python，据说是从趋势那边搬过来的。webdriver里面，IEdriver是运行最慢的，因此每次跑一遍用例都要花上4个小时

，这个如果在工作日跑的话，半天工作时间就没了，如果在下班后跑，发现问题又不能及时调试，很烦……

Java里的webdriver有个好东西是htmlunit，这个在python版的webdriver里却没有，应该跟htmlunit纯用java写的有关。htmlunit跑用例可以不打开浏览器在后台跑，因此在webdriver里面是最快的。python里面虽然没有htmlnuit，但是有个第三方库是Jpype，可以通过模拟java虚拟机直接调用jar包！因此我的想法是用java写个接口把htmlunit常用方法再封装下，然后用python通过jpype来调用接口。

由于后来其他原因失败了，导致这边只封装了最基本的接口。这里拿网易邮箱来做测试，python代码：

#coding=utf8
import jpype
import time
import os.path
start=time.time()
jarpath=os.path.join(os.path.abspath('.'),'E:/lib')
print jarpath
jvmPath=jpype.getDefaultJVMPath()
jpype.startJVM(jvmPath,"-Djava.ext.dirs=%s"%jarpath)
jpype.java.lang.System.out.println("hello world!")
javaclass=jpype.JClass("htunit.htunit")
temp=javaclass()
temp.deletecookie()
url='http://mail.163.com'
username='****'
pwd='****'
id='loginBtn'
temp.get(url)
temp.SetInputTextById("idInput", username)
temp.SetInputTextById("pwdInput", pwd)
temp.ClickById(id)
print time.time()-start

上面java代码中如果24行不注释，注释25行则会调用IE接口。下面是在我机器上跑的时间对比：
