利用loadrunner的net插件测试c#程序的性能

Loadrunner V9.5

Visual Studio 2005

按照顺序安装lr，vs2005，lr的net2005插件；

安装完成后，会在vs2005的的菜单栏多出Vuser

在vs种开发脚本，如下：

using System;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using LoadRunnerUserTest.WebReferenceTest;
using LoadRunnerUserTest.WebReferenceMeeting;
using System.IO;

namespace LoadRunnerUserTest
{
    /// <summary>
    /// Summary description for VuserClass.
    /// </summary>
    [ClassInterface(ClassInterfaceType.AutoDual)]
    public class VuserClass
    {
        LoadRunner.LrApi lr;

        public VuserClass()
        {
            // LoadRunner Standard API Interface ::             DO NOT REMOVE!!!
            lr = new LoadRunner.LrApi();
        }

        // ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
        public int Initialize()
        {
            // TO DO: Add virtual user's initialization routines

            return lr.PASS;
        }

        // ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
        public int Actions()
        {
            lr.rendezvous("IMlogin");

            // TO DO: Add virtual user's business process actions

            WebReferenceTest.UserService request = new WebReferenceTest.UserService();

            meetingEntity.MeetingMembers[0] = member1;

           
           
            try
            {

                lr.start_transaction("IMlogin");
                //string userName = lr.eval_string("{user}");

                result = request.Login("usr00050"/*userName*/, "LuwKEXgt1TGqnQ/KxLve8a9xH", "F04DA23167EA", "11111").IsSuccessfull;
                //lr.log_message("now user is:" + userName);

                //errorCode = request.SearchUsersByName(userName, "1111", out userEntities).ErrorCode.ToString();
                if (!result)
                {
                    lr.log_message("the reason of login fail is  " + errorCode);

                    StreamWriter SW = File.AppendText("D:\\log.txt");

                    SW.WriteLine("####");
                    SW.Close();
                    lr.end_transaction("IM_MeetingCreated.", lr.FAIL);
                }
                else
                {
                    lr.end_transaction("IM_MeetingCreated.", lr.PASS);
                }
               

            }
            catch (Exception ex)
            {
               // lr.log_message("Exception message:" + ex);
                //Console.WriteLine(ex.ToString());
            }
            finally

               // lr.log_message("meetingErrorCode is " + meetingErrorCode);
                //Console.WriteLine(result);
                //Console.WriteLine(errorCode);
            }

            //lr.end_transaction("IM login",lr.AUTO);
        }

        // ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
        public int Terminate()
        {
            // TO DO: Add virtual user's termination routines

            return lr.PASS;
        }

    }
}

脚本开发完成后，在vs种编译通过，然后在lr种运行，不能直接在lr种修改脚本以及参数化等操作；

不过在controller种，遇见一个问题，我设置的集合点函数无法识别出来；

有做这种性能测试的同学，可以参考我的脚本及过程

我在之前也是尝试了一周才找到这种方式测试c#程序的性能；我们程序是c/s架构的；
