Introduction to JMeter

JMeter is a software that can perform load test, performance-oriented business (functional) test, regression test, etc on different protocols or technologies.

JMeter is an Open Source testing software. It is 100% pure Java application for load and performance testing. JMeter is designed to cover categories of tests like load, functional, performance, regression, etc. This brief description will give an understanding on JMeter framework that is needed to test an enterprise level application to deliver it with robustness and reliability.

  • Performance Test − This test sets the best possible performance expectation under a given configuration of infrastructure. It also highlights early in the testing process if any changes need to be made before the application goes into production.
  • Load Test − This test is basically used for testing the system under the top load it was designed to operate under.
  • Stress Test − This test is an attempt to break the system by overwhelming its resources.

JMeter is a Java desktop application with a graphical interface that uses the Swing graphical API. It can therefore run on any environment / workstation that accepts a Java virtual machine, for example − Windows, Linux, Mac, etc.

Following are some of the features of jMeter −

  • Being an open source software, it is freely available.
  • JMeter can conduct load and performance test for many different server types − Web – HTTP, HTTPS, SOAP.
  • It is a platform-independent tool. On Linux/Unix, JMeter can be invoked by clicking on JMeter shell script. On Windows, it can be invoked by starting the jmeter.bat file.
  • It has full Swing and lightweight component support (precompiled JAR uses packages javax.swing.* ).
  • JMeter store its test plans in XML format. This means you can generate a test plan using a text editor.
  • Its full multi-threading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by separate thread groups.
  • It is highly extensible.
  • It can also be used to perform automated and functional testing of the applications.

JMeter simulates a group of users sending requests to a target server, and returns statistics that show the performance/functionality of the target server/application via tables, graphs, etc.

The above mentioned is a brief about JMeter. Watch out this space for the latest Trends in Technology.
