Jmeter is an exceptional tool for general performance tests. It’s simple, flexible, and scalable for our performance testing needs. Almost all performance test projects have used it. It was originally developed to test web applications, but because it has been expanded to include other test functions. Apache JMeter is an open-source Java software used as a load test tool to analyze and measure performance of a variety of services. It is pure open-source Java software for testing web applications or FTP applications. JMeter is an software that can perform load tests, commercial performance tests (functions), regression tests, etc. Stefano Mazzocchi of the Apache Software Foundation is the original developer of JMeter. He wrote it mainly to test the performance of Apache JServ (now called the Apache Tomcat project). Apache then redesigned JMeter to improve the graphical user interface and add functional test functions. JMeter is Java desktop application with a graphical interface that uses the Swing graphical API. Therefore, it can be run in any environment/workstation that accepts a Java virtual machine, e.g., Windows, Linux, Mac.

The protocols supported by JMeter−

Web − HTTP, HTTPS site ‘web 1.0’ web 2.0 (ajax, flex , flex-was-amf)

Web Services − SOAP / XML-RPC

Database via JDBC drivers

Directory − LDAP

Messaging Oriented service via JMS

Service − POP3, IMAP, SMTP

FTP Service

What is Performance Testing?

It is very important to check the product works as expected or required. Unfortunately, we discovered this trap after the delivery of the product. However, performance is an inevitable factor these days, especially for web and mobile applications, as the user’s strength is too great for any application.

Performance testing is defined as a type of software testing to ensure that applications run under the expected workload.

It focuses on some software factors, such as:

Speed: check if the application response is fast.

Stability: check if the application is stable under different loads.

Scalability – It determines the maximum user load.

Performance tests are important in real-time, especially concerning customer satisfaction. Several performance testing tools are available, such as:

Apache JMeter

LoadRunner

WebLOAD

LoadUI

LoadView

NeoLoad

How does JMeter perform Testing?

Let’s take a look at different steps JMeter took during the test:

1. Create a request and send it to the server.

2. Receives the response from the server, collects it, and displays these details in a diagram or graph.

4. The test result is generated in various formats such as text, XML, JSON so that the tester can analyze the data.

JMeter Features

It is available for free as open-source software.

It has a simple and intuitive graphical interface.

JMeter can perform load and performance tests for different types of servers: Web-HTTP, HTTPS, SOAP, database via JDBC, LDAP, JMS, Mail-POP3, etc.

On Linux / Unix, you can invoke JMeter by clicking on the JMeter shell script.

On Windows, it can be started by starting the jmeter.bat file.

Full support for swing and lightweight components (the precompiled JAR uses the java.swing.

This means that you can create a test plan with a text editor.

The full multithreaded structure allows simultaneous scanning of many threads and simultaneous scanning of functions other than groups of separate threads.
