It is very user-friendly. We just upload the script, and the dashboards are very informative. It's useful for both the person conducting the test and the higher management, like project managers or senior executives, who may not know about the test. They can easily view the results and gain valuable insights. Additionally, monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version.

How does JMeter work?

JMeter sends requests to a target server by simulating a group of user requests. Then it collects and calculates statistics on the performance of the target. This target can be a server or an application.

You can test the performance of static resources, such as JavaScript or HTML, and dynamic resources, such as JSP, Servlets, and AJAX. It is also helpful to determine how many concurrent users your website can handle.

There are two main tests you can carry out with JMeter: load test and stress test. The load test models expected usage of a server by simulating multiple users accessing the web server simultaneously. The stress testing aims to find the maximum load capacity of the server or application.

Apache JMeter Key Features

JMeter enables fast test plan recording, building, and debugging via a featured test IDE (integrated development environment).
Command-line mode allows carrying out load tests from any OS compatible with Java.
JMeter can extract data from most popular response formats, such as HTML, JSON, XML.
JMeter is entirely portable.
