1.robotframework和loadrunner集成

一般我们进行完功能测试，都需要进行下性能测试，那么这章我来介绍下，RobotFramework与loadrunner性能测试的融合，即运行完自动化功能测试，借助RobotFramework的Remote库来执行性能测试。

1.1准备条件

A:一台pc，系统win7，安装有python、RobotFramework及ride。

B:一台pc，安装有loadrunner，python，IP为192.168.3.124

C:一台服务器

1.2结构图

1.3在loadrunner机器上安装robotremoteserver.

下载robotremoteserver.py（Remote Server）并修改

 Robotremoteserver.py为远程服务脚本，客户端通过它来调用服务器端的测试库来执行测试，下载地址如下：

http://robotframework.googlecode.com/hg/tools/remoteserver/robotremoteserver.py

或者https://github.com/robotframework/PythonRemoteServer

> pip install robotremoteserver

把Robotremoteserver.py和Exampleremotelibrary.p.py存放到C:\lr_get_script\rf_lr

都放置在安装loadrunner的PC上。

Robotremoteserver.py中需要修改的地方，就是host和port：

  def __init__(self, library, host='192.168.8.231',port=8277, allow_stop=True):

      SimpleXMLRPCServer.__init__(self, (host, int(port)), logRequests=False)

      self._library = library

      self._allow_stop = allow_stop

      self._register_functions()

      self._register_signal_handlers()

      self._log('Robot Framework remote server starting at %s:%s'

                  % (host, port))

       self.serve_forever()

 修改： 设置host和port为安装loadrunner的测试机ip及端口

run_performance_test函数为调用loadrunner的wlrun.exe，执行给出的场景脚本。

Exampleremotelibrary.py

import os

import sys

class ExampleRemoteLibrary:

   """Example library to be used with Robot Framework'sremote server.

    Thisdocumentation is visible in docs generated by _libdoc.py_

   starting from Robot Framework 2.6.2.

   """

    def__init__(self):

       """Also this doc should be in shown in librarydoc."""

    defrun_performance_test(self,scriptname):

       run_pfm_str = ''

       run_pfm_list = ["wlrun.exe -TestPath ",scriptname," -port8080 -Run -DontClose"]

        #运行完loadrunner后不关闭

        #run_pfm_list= ["wlrun.exe -TestPath ",scriptname," -port 8080 -Run "]

        #运行完之后自动关闭，结果在control里面配置成自动保存

       os.chdir("C:\\Program Files (x86)\\Hp\\LoadRunner\\bin")

       os.system(run_pfm_str.join(run_pfm_list))

if __name__ == '__main__':

    fromrobotremoteserver import RobotRemoteServer

   RobotRemoteServer(ExampleRemoteLibrary(), *sys.argv[1:])

1.4运行服务端测试库

 在安装loadrunner的PC上执行如下命令：

>c:\lr_get_script\rf_lr>pythonExampleremotelibrary.p.py

Robot Framework remote server at192.168.3.124:8277 started.

1.5 在另外一台机器上rf上先加入Remote库

注意：Remote后面的参数192.168.3.124:8270是测试执行机（安装loadrunner的PC）的ip及端口

1.6 用例写作及执行，在用例中调用远程测试库

我们调用run_performance_test这个函数

运行用例后自动打开lr后开始自动跑性能测试

2.远程服务器端192.168.3.124创建远程python测试库（Test Library）

2.1TestLibrary.py

#coding=utf-8

import sys

from robotremoteserver importRobotRemoteServer

__version__ = '1.0'

class TestLibrary(object):

   #def __init__(self):

   #   pass

   def Test_add(self,a,b):

       if(a>b):

            falg=False

            return False

       else:

            flag=True

            return flag

   def test1(self):

       """test 1"""

       print "test1"

   def test2(self):

            """test2"""

            print "test1"

   def test3(self):

            """test3"""

            print "test3"   

if __name__ == '__main__':

   RobotRemoteServer(TestLibrary(),'192.168.3.124','8270')

2.2__init__.py (rf自定义库)

# coding=utf-8

from TestLibrary import TestLibrary

version = '1.0'

class TestLibrary(TestLibrary):

     ROBOT_LIBRARY_SCOPE = 'GLOBAL'

2.3  配置robotremoteserver.py

通过>pip install robotremoteserver

或者https://github.com/robotframework/PythonRemoteServer 下载robotremoteserver安装包后安装

把C:\Python27\Lib\site-packages\Robotremoteserver.py 

复制到C:\Python27\Lib\site-packages\TestLibrary\Robotremoteserver.py

然后编辑Robotremoteserver.py

class RobotRemoteServer(object):

    def __init__(self, library,host='192.168.3.124', port=8270, port_file=None,

                 allow_stop='DEPRECATED',serve=True, allow_remote_stop=True):

       """Configure and start-up remote server.

192.168.3.124为远程服务器ip地址

port=8270为对应的服务器端口

2.4 运行TestLibrary.py

C:\Python27\Lib\site-packages\TestLibrary>pythonTestLibrary.py

Robot Framework remote server at192.168.3.124:8270 started.

在Server端运行此py文件，只有先在Server端运行起来该库文件，在RobotFramework 控制端才可以添加Remote库。

被远程控制的Server端的防火墙要关闭

2.5 RobotFramework 控制端添加Remote库，过程如下，alias可写可不写，当Server端库文件很多的时候，要写上作为区分：

2.6在另外一台安装有rf的机器里面配置库创建测试用例

新建的testcase里，就可以使用自定义的MyLibrary中的关键字了，如test1,test2,test3

创建exampleremotelibrary.py脚本，脚本内容如下： 

import os

import sys

class ExampleRemoteLibrary:

   """Example library to be used with Robot Framework'sremote server.

   This documentation is visible in docs generated by _libdoc.py_

   starting from Robot Framework 2.6.2.

   """

   def __init__(self):

       """Also this doc should be in shown in librarydoc."""

    defrun_performance_test(self,scriptname):

        run_pfm_str= ''

        run_pfm_list= ["wlrun.exe -TestPath ",scriptname," -port 8080 -Run-DontClose"]

       os.chdir("C:\\Program Files (x86)\\Hp\\LoadRunner\\bin")

       os.system(run_pfm_str.join(run_pfm_list))

if __name__ == '__main__':

   from robotremoteserver import RobotRemoteServer

   RobotRemoteServer(ExampleRemoteLibrary(), *sys.argv[1:])

run_performance_test函数为调用loadrunner的wlrun.exe，执行给出的场景脚本。
