Apache JMeter

Apache JMeter

2-day course

Apache JMeter is an open-source software application designed to test functional behavior and measure the performance of web applications. Its primary use is for testing web application, but it can also test other services. As software applications grow in complexity, performance testing becomes crucial.

JMeter can be used to simulate a heavy load on a server, group of servers, network, or object to test its strength or to analyze overall performance under different load types. This course aims to impart knowledge about how to effectively use JMeter for performance and functional testing.
