What is JMeter:
JMeter is an open-source software application developed by the Apache Software Foundation. It is a popular tool used for performance testing, load testing, and functional testing of web applications. JMeter can simulate a large number of users, requests, and traffic to a web application, and measure the application’s performance under heavy load.
JMeter supports various protocols such as HTTP, HTTPS, FTP, JDBC, LDAP, JMS, TCP, and many more. It has a user-friendly GUI that allows users to create test plans and scenarios easily. JMeter also provides command-line mode and distributed testing capabilities, which allow for testing large-scale applications.
