The Apache JMeterTM is pure Java open source software, which was first developed by Stefano Mazzocchi of the Apache Software Foundation, designed to load test functional behavior and measure performance. Apache JMeter is a testing tool used for analyzing and measuring the performance of different software services and products. It is a pure Java open source software used for testing Web Application or FTP application.
It is used to execute performance testing, load testing and functional testing of web applications. JMeter can also simulate a heavy load on a server by creating tons of virtual concurrent users to web server
What is Performance Testing:
Performance Testing is defined as a type of software testing to ensure that software applications will perform well under their expected workload. It focuses on certain factors of a Software Program such as:
It is very important to verify whether the product meets expected or required performance. Unfortunately, we figure out this pitfall post-delivery of the product. But performance has become an inevitable factor nowadays, especially for web and mobile applications as the user strength is very huge for each application.
Tools used for Performance Testing:
Performance testing is significant in real time, particularly from a point of view of customer satisfaction. There are several performance testing tools available such as:
How does JMeter perform Testing?
Let’s have a look at the different steps performed by JMeter during testing:
Apache JMeter – How is works?
The web server handles or carries loads of lots of applications & its user, so there is a need to know how JMeter helps us to handle the performance of Web server to manage simultaneous users or their applications.
For Example: Online purchasing site, how they handle their sale when there are lots of users are accessing the same page of the product. To handle or check that kind of performance of application or server we must do a high performance or a load testing using JMeter.
There are three different approaches to JMeter testing:
Plugins & Protocols:
JMeter works with different plugins & Protocols, Also Off-site developers can simply spread JMeter with custom plugins.
JMeter works on many protocols which are:
Working features of JMeter:
JMeter works as a number of users send a request for accessing some server & shows the performance by the listeners like tables, graphs etc.
Characteristics of Apache JMeter
Why People choose Apache JMeter for Performance & Load testing. Here are some characteristics which are mentioned below:
JMeter is a pure Java application and should run correctly on any system that has a compatible Java implementation.
Here is the list of an operating system compatible with JMeter:
JMeter GUI: Test Plan & Workbench
As soon as you launch JMeter, you will see 2 elements
What is a Test Plan? Test Plan is where you add elements required for your JMeter Test.
It stores all the elements (like ThreadGroup, Timers etc.) and their corresponding settings required to run your desired Tests.
What is WorkBench? The WorkBench simply provides a place to store test elements temporarily. WorkBench has no relation with Test Plan. JMeter will not save the contents of the WorkBench. It only saves the contents of the Test Plan branch.
