Introduction to Jmeter

JMeter is a free and open-source testing program. It is a completely Java-based program for load and performance testing. JMeter is primarily used to test Web applications and FTP applications, although it is now also useful for functional testing, JDBC database connections, Web services, generic TCP connections, and OS native processes.

JMeter Features:

The following are some of JMeter's key features:

1. An open-source program:
   JMeter is a free and open-source software program. It is therefore freely accessible.
   
   
2. User-friendly GUI:
   It has a simple and interactive GUI.
   
   
3. Support for numerous server types:
   JMeter is capable of performing load and performance tests for a wide range of server types, including Web - HTTP, HTTPS, SOAP, Database via JDBC, LDAP, JMS, Mail - POP3, etc.
   
   
4. Platform independent:
   As it was created and written using Java, it is a platform-independent utility.
   
   
5. Framework:
   It is a multi-threading framework that enables simultaneous sampling of various functions by various threads as well as by various thread groups. It can be extended greatly.

Working of JMeter:

JMeter delivers requests to a target server while simulating a group of users. Thus, the target server's functionality and performance are demonstrated by the statistics that are returned.
