    • JMETER The load testing tool By : Pritesh Patel
    • WHAT IS LOAD TESTING?
      • Load testing is the process of putting demand on a system or device and measuring its response.
      • Types of tests
        • Performance Testing - is usually defined as the process of exercising the system under test by feeding it the largest tasks it can operate with
        • Stress Testing - to break the system under test by overwhelming its resources or by taking resources away from it
    • WHY LOAD TESTING?
      • Find Performance issue with your website
      • Discover how many users your website support in order to prevent disaster.
      • Finding task which required performance improvement.
    • HOW TO AVOID LOAD TESTING
      • My client not ready to pay for testing?
      • My manager has assign lots of work with very tight deadline.
      • I know there will be 2 to 3 users will visit this application and server can handle that much load.
    • LOAD TESTING TOOLS
      • Flood , open source from and for Apache
      • JMeter , an open source tool
      • LoadStorm , free and commercial hosted service (25 virtual users are free), offering different features for load, stress, regression, and endurance testing of web apps
      • NeoLoad , commercial, for Windows, Linux, Solaris
      • OpenLoad , commercial load testing tool and hosted service
      • OpenSTA , an open source tool
      • PureLoad , commercial, multiplatform load testing tool
      • PushToTest TestMaker , an open source testing framework (load testing and more)
      • QEngine , free and commercial, from AdventNet (free edition supports 5 virtual users)
      • Reality LOAD XF , commercial, in the Gomez line of remote services
      • riatest , commercial, multiplatform Flex UI testing Silk family of tools, commercial
      • SQLQueryStress Performance Testing Tool , free, for testing SQL Server StressIT , commercial and free
      • The Grinder , an open source tool
      • Microsoft Visual Studio Team System 2008 (and 2005), commercial, for Windows, which includes Load Test Analyzer and Load Test Monitor tools.
      • WAPT , W eb AP plication T esting tool, a commercial product, for Windows
      • WatchMouse , commercial hosted load testing service
      • WebKing , commercial, multiplatform
      • WebServer Stress Tool , commercial and free, from Paessler
    • WHY JMETER?
      • Can load and performance test many different server types:
        • Web - HTTP, HTTPS
        • SOAP
        • Database via JDBC
        • LDAP
        • JMS
        • Mail - POP3(S) and IMAP(S)
      • Full multithreading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by seperate thread groups.
      • Careful GUI design allows faster operation and more precise timings.
      • Caching and offline analysis/replaying of test results.
    • CONTINUE…
      • Highly Extensible:
        • Pluggable Samplers allow unlimited testing capabilities.
        • Several load statistics may be chosen with pluggable timers .
        • Data analysis and visualization plugins allow great extendibility as well as personalization.
        • Functions can be used to provide dynamic input to a test or provide data manipulation.
        • Scriptable Samplers (BeanShell is fully supported; and there is a sampler which supports BSF-compatible languages)
    • INSTALLING JMETER (ON WINOW)
      • Install Java (2.2. or higher)
      • Download JMeter http://jakarta.apache.org/site/downloads/index.html
      • Add path of java installation in environment path variables.
    • RUNNING JMETER IN WINDOWS
      • Open command prompt (user administrative mode to avoid unnecessary hassle).
      • Traverse to [jmeter installation path]in
      • Run Jmeter.bat If you are running test behind firewall try following argument to pass with command prompt.
        • -H [proxy server hostname or ip address] -P [proxy server port] -N [nonproxy hosts] (e.g. *.apache.org|localhost) -u [username for proxy authentication - if required] -a [password for proxy authentication - if required]
    • ELEMENTS OF TEST PLANS
      • Thread Group
        • Setup number of thread
        • Set up ramp up period
        • No. of times test exectues
      • Controllers
        • Sampler (Send Request to Server)
        • Logical Controller (Customize logic to send request)
      • Listener
        • Graph Result
        • View Results Tree and many more.
      • Timers
        • Delay next request for certain amount of time
    • CONTINUE….
      • Assertions
        • Allow you to assert fact about responses received from HTTP request
      • Configuration Elements
        • Allow you configure settings
      • Preprocessor
        • Execute prior to sampler request
      • PostProcessor
        • Execute some action after sampler request
    • CREATING YOUR FIRST WEB TEST PLAN
    • ADDING USERS
      • 5 users send 3 requests on cfminds.com and repeat it twice. (5 users x 3 requests x 2 repeat = 30 requests)
      • Right click on test note >> Add >> Thread (users) >> Thread Group
    • ADD DEFAULT HTTP REQUEST
      • You can add default http request setting from ADD >> Config Element >> HTTP request default.
      • This will let you define default http parameter for every request.
    • ADDING HTTP REQEST ELEMENT
      • You can add it from ADD> Sampler >> HTTP Request
    • ADDING LISTNER TO VIEW RESULT
      • Listner responsible for storing all of the results of our HTTP request and presenting in Visualize mode.
    • DEMO
    • GRAPH COMPARISON (5 USERS VS 50 USERS) 5 Users 50 Users
    • 5 Users 50 Users
    • HTTP COOKIE MANAGER
      • You can add cookie manager by right clicking on test plan Add >> Config Element >> HTTP Cookie Manager.
      • Usage:
        • Store and sends cookies just like browser
        • Maintain separate cookie for each thread but share in all requests.
    • LOGIN IN TO SECURE PAGES
      • Find out action page of login form.
      • Create HTTP Request Sampler and pass username, password and other required data.
      • Most important : Add HTTP Cookie manager if session stores in cookie or depends on cookie.
    • DEMO
    • LOGIN WITH DIFFERENT USER IN EACH THREAD
      • Create CSV file with list of username and password
      • Store in same folder where your test stores
      • Add CSV Data set into your test tree from config elements
      • Add ${USER},${PASS} in request sampler as parameter.
    • CONTROLLING REQUEST LOGIC
      • Logic Controllers can be used to control flow.
    • DEMO
    • RECORDING YOUR TEST PLAN
      • JMeter Proxy can use to record all request send to server.
      • Create test plan with default http testing
      • Add HTTP Proxy Server in Workbench node.
        • Define port# of proxy server
        • Define URL Pattern to include/exclude
          • .* - all
          • .*/.cfm – CFM pages
          • .*/.gif – GIF file etc.
      • Start Proxy server.
      • Setup Proxy server on your browser.
    • DEMO
    • JMETER DISTRIBUTED TESTING
      • JMeter client machine may not able to simulate enough users to stress server.
      • Control multiple machine to run JMeter without copying test samples to different machine.
      • Configuration:
        • Copy same version of JMeter to different computer.
        • Add remote node IP in JMeter.proeprties file.
        • Run JMeter on remote machine using /JMETER_HOME/bin/jmeter-server (in command prompt)
        • Start JMeter GUI in host machine.
        • Select any test plan.
        • Go to Run >> Remote Start >> Remote IP Address.
    • DEMO
    • YEAH… IT’S OVER NOW..
