  • GETTING STARTED: SCRIPTING WITH JMETER Apache JMeter is a great tool for simulating performance testing on web-applications, but it may seem tricky at first glance. Learn how to create your first JMeter script from scratch.
  • GETTING STARTED • Download JMeter from the official Apache JMeter website • Unzip the distribution and copy it a folder on your computer. • You need to have JRE 1.6 or above to run JMeter, because it's written in pure JAVA. • If you are running WINDOWS- Go to $JMETER_HOME/bin and run jMeter.bat or If you are using *nix –Go to JMeter
  • TEST PLAN (1) The Test Plan is the core element of the test script. 2 tables and 3check-boxes.
  • TEST PLAN (2) #1 Table • User Defined Variables, allows us to set variables, which can be used in any other part of the script • These values can be set up as a variables simply eliminating the need to update the script. #2 Table • Is used for making test plan databases, in order to make the JDBC driver visible for JMeter and able to execute the SQL queries. • Add JDBC *.jar to this table, and JMeter will recognize it.
  • CHECK BOX #1 If this option is checked, than all Thread Groups will be executed one by one. This may be useful in cases such as if the first Thread Group prepares test-data for a test, and the next one uses this set. Run Thread Group Consecutively
  • CHECK BOX #2 Some actions, like restoring the system after testing to a default state may be assigned to tearDown Thread Groups. Run tearDown Thread Groups after shutdown of main threads
  • CHECK BOX #3 JMeter can also be used for functional tests because it has a set of elements which allow page retrieval from the server. Saves much more information about each request using the functional test mode. Consumes more memory for processing data stream. Functional Test Mode
  • THREAD GROUPS Every JMeter test plan should contain at least one Thread Group and it will be the first element added to the test plan.
  • HTTP REQUEST DEFAULTS Set default values for your HTTP Request controllers use: For example, if you are creating a Test Plan with 25 HTTP Request controllers and all of the requests are being sent to the same server, you could add a single HTTP Request Defaults element with the "Server Name or IP" field filled in. Use the same URL for all requests. Add the site that will be stress tested.
  • CONSTANT TIMER Users never click links one by one, without any delay. Naturally, there is a delay between thoughts and therefore user think-time needs to be emulated. JMeter has a set of Timers, which allows users to set up a pause between different requests. Add Constant Timer to generate the delay for the fixed amount of time.
  • HTTP COOKIE AND CACHE MANAGER HTTP Cookie Manager: used for emulating browser's work with cookies. HTTP Cache Manager: used for saving downloaded pages in cache during the first request, so they could be returned to Listener without downloading. This approach, obviously, has influence on test results.
  • VIEW RESULTS TREE This element is only needed during debugging tests. View Results Tree is in regards to memory consumption because it stores, in memory, all the results of requests. If it is used while there are many virtual users, memory will run out. So remove or disable the View Results Tree all other graphic listeners before running a test.
  • RUNNING A LOAD TEST WITH BLAZEMETER •VL If you already have your BlazeMeter account set up, you can simply click “Add test”. If not, create your FREE account now!
  • UPLOAD TEST SCRIPT Upload the JMeter script to BlazeMeter Adjust the test plan settings using the controls on the right side of the page. Press SAVE. Press START.
  • RESULTS WELL DONE! Load Report Tab All graphs represent KPIs (Key Performance Indicators) measured during the load.
