JMeter

US Soft Technologies > JMeter

Apache JMeter is an open-source performance testing tool designed to analyze and measure the performance of web applications and a wide range of services. Originally developed for web application testing, JMeter has evolved to support various protocols such as HTTP, HTTPS, SOAP, REST, FTP, JDBC, and more. It allows testers to simulate heavy loads on servers, groups of servers, or networks to test strength and performance under different conditions. With its user-friendly GUI, script recording capabilities, and integration support with CI/CD tools, JMeter is widely used for load testing, stress testing, and functional testing, making it a versatile choice in the software testing industry.

  • Analyzing Bottlenecks

 

What is Apache JMeter?

Apache JMeter is an open-source tool designed for performance and load testing of web applications and various other services. It simulates multiple users to evaluate the performance of applications under different loads.

Yes, although it’s primarily used for performance testing, JMeter can also be used for basic functional testing of web applications and APIs.

A Test Plan is the top-level container in JMeter that holds all test components such as Thread Groups, Samplers, Logic Controllers, Listeners, etc.
