What is JMeter ?
  • The Apache JMeterTM is pure Java open source software, which was first developed by Stefano Mazzocchi of the Apache Software Foundation,
  • designed to load test functional behavior and measure performance.
  • You can use JMeter to analyze and measure the performance of web application or variety of services.
  • Performance testing means testing a web application against heavy load, multiple and concurrent user traffic.
  • JMeter originally is used for testing Web Application or FTP application.
  • Nowadays, it is used for functional test, database server test etc.
JMeter advantages
  • Open source license: JMeter is totally free, allows developer use the source code for the development
  • Friendly GUI: JMeter is extremely easy to use and doesn't take time to get familiar with it.
  • Platform independent: JMeter is 100% pure Java desktop application. So it can run on multiple platforms
  • Full multi-threading framework: JMeter allows concurrent and simultaneous sampling of different functions by a separate thread group.
  • Visualize Test Result: Test result can be display in a different format such as chart, table, tree and log file.
  • Easy installation: You just copy and run the *.bat file to run JMeter. No installation needed.
  • Highly Extensible: You can write your own tests. JMeter also supports visualization plugins allow you extend your testing.
  • Multiple testing strategy: JMeter supports many testing strategies such as Load Testing, Distributed Testing, and Functional Testing.
  • Simulation: JMeter can simulate multiple users with concurrent threads, create a heavy load against web application under test.
  • Support multi-protocol: JMeter does not only support web application testing, but also evaluate database server performance. All basic protocols such as HTTP, JDBC, LDAP, SOAP, JMS, and FTP are supported by Jmeter.
  • Record & Playback: Record the user activity on the browser and simulate them in web application using Jmeter.
  • Script Test: Jmeter can be integrated with Bean Shell & Selenium for automated testing.
