  • 1. JMETER The load testing tool By : Pritesh Patel
  • 2. 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
  • 3. 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.
  • 4. 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.
  • 5. 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
  • 6. 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.
  • 7. 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)
  • 8. 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.
  • 9. 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]
  • 10. 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
  • 11. 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
  • 12. CREATING YOUR FIRST WEB TEST PLAN
  • 13. 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
  • 14. 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.
  • 15. ADDING HTTP REQEST ELEMENT
    • You can add it from ADD> Sampler >> HTTP Request
  • 16. ADDING LISTNER TO VIEW RESULT
    • Listner responsible for storing all of the results of our HTTP request and presenting in Visualize mode.
  • 17. DEMO
  • 18. GRAPH COMPARISON (5 USERS VS 50 USERS) 5 Users 50 Users
  • 19. 5 Users 50 Users
  • 20. 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.
  • 21. 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.
  • 22. DEMO
  • 23. 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.
  • 24. CONTROLLING REQUEST LOGIC
    • Logic Controllers can be used to control flow.
  • 25. DEMO
  • 26. 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.
  • 27. DEMO
  • 28. 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.
  • 29. DEMO
  • 30. YEAH… IT’S OVER NOW..
