Running JMeter

1)      Open JMeter root folder i.e. C:\jmeter

2)      Open bin directory inside jmeter folder

3)      Double click on “jmeter.bat” file.

4)      JMeter will be launched.

The window should be open like this with a command prompt window-

In this window you will be able to see the tabs-  1  : Test plan, 2 : WorkBench

As Jmeter is a usefull tool for load testing,so the first and important this is to record the script.

Script is whatever actions you have performed in website.

Now to record the script for testing,first of all right click on workbench and add http proxy server.

After selecting http proxyserver the window will be like:

Now  we will go to the test plan and right click on it and add thread group like:-

After selecting thread group:-

 [In this window number of thread users=no of users

Ramp-up period(in seconds):delay b/w every user

Loop count:how many time you want to repeat the test]

(Note:-By default the values will be as in the window)

Now to record the test first of all open the internet explorer,go to the tools then internet options,go to connection tab,click on lan settings.check the proxy server and give the Address:-localhost,port no-8080.click on ok and again click on ok.

Now got to the jmeter window and select http proxyserver,and click on start.

Open the website in internet explorer of which you want to test load.I am assuming the website is http://www.google.com/.  And performing some search actions.

Now move back to the jmeter window and select http proxyserver and click on stop. Then clich on thread group:-

Below thread group all are the http requests or we can say it as the recorded script.

Now here is the thing which is very important is that if you will put the load on web server from your own computer and the numbers of users are more than 1000 or 500.That time it might be possible that your computer or jmeter will hang.

To solve this problem we can use Destributed load method in Jmeter-
