What is JMeter? | Introduction, Features & Advantages

This article talks about one of the recent questions being asked to us what is JMeter and how it works. We will also walk through the direct advantages of this free-to-use software which stays in our likes all the time.

What is JMeter

It is quite a popular open-source load simulation tool and is based on a Java-based load testing framework and is made to be a performance test tool, stress test tool, and even a performance testing tool. It can be used for unit testing, performance testing, and acceptance tests (although it’s best suited for performance or acceptance tests). JMeter is a very stable and secure tool. A large portion of the JMeter codebase was written by Jim Whitehead, who is the creator of JMeter. It has been around since 1999, and it's still being maintained by the core developers at Pivotal Labs.

JMeter can be used to simulate realistic traffic bursts on your website or application under various conditions like high load, low latency, etc. It has a small learning curve because it’s easy to use. JMeter is not very complicated and allows you to get up and running with it in minutes. It's ready-to-go software and has only basic settings, so there's no need for advanced scripting skills or coding knowledge. It's used by many companies, including Netflix and Etsy, to test their web applications. Jim Whitehead created JMeter and continues to be involved in its development. He also contributes code as an open-source contributor at GitHub.

How JMeter works?

A JMeter project requires a configuration file, at least one XML file to control the application's behavior, and a data set that contains measurements of the performance of your application. The configuration file is used by the script runner and shows what actions are available in each step. It also defines how HTTP requests should be processed and gives parameters for running those steps.

The XML files contain information about what variables can be changed during execution (the "configuration"), how they will change (the "action"), and when they take effect (when something happens). This structure enables flexibility in development without having to write code yourself every time you want something different done differently; instead, all you have to do is define some basic syntax rules for your custom scripting language which makes it easy for other team members or consultants later on who may not know Java themselves.

The above paragraphs talked about the question “what is JMeter “, now let’s talk about its structure. JMeter follows the three-tier architecture pattern and can be used to test applications' in-memory models, database models, and third-party APIs. JMeter follows the three-tier architecture pattern, which means that it has three main components:

  • The client or user interface layer - This component interacts with JMeter through HTTP requests and responses or by using plugins specified in the configuration file.
  • The server (or controller) layer - This component processes requests from clients and produces responses according to their needs. It also takes care of managing state changes between phases so that there are no page flickers when switching between phases, etc.
  • Data Base: The server saves all and collects the statistical info. This info after calculations are completed is compiled in particular report formats. 

Features of JMeter:

>JMeter can simulate any type of test, such as a web page, an application, or even a hardware device. In addition to simulating real browsers, JMeter also lets you simulate web servers and other types of devices (such as routers). With this feature, you can easily verify your application's performance under different load scenarios.

>JMeter allows you to test web pages for performance on a wide variety of platforms. It is a load simulation tool that allows you to test web pages for performance on a wide variety of platforms. When it comes to performance testing of Apps and games, we recommend using the PerfDog, a state-of-the-art performance and quality improvement platform from WeTest which has tons of features to love and has practical implications in the software development process.

>JMeter can simulate web pages, applications, and hardware devices (such as servers) to see how they perform under real-world conditions. The application or device is represented by what’s called an “agent," which is just like any other JMeter module; in this case, we have our agent—the browser going through its paces. This means that you don't need any special skills or technical knowledge about how these things work; instead, all you need is some basic instructions on what type of resources your application needs and where those resources will come from (e.g., an HTTP request). 

> By using JMeter with these basic settings we can simulate hundreds if not thousands of users per second without having any trouble getting things done efficiently enough so that even large companies like Google could use them without breaking their bank accounts due to expensive licensing fees. And part is that it's easy to use JMeter because it's written in Java and comes with a command line interface (CLI). You can also develop scripts using Groovy or Scala language features if you prefer that approach over scripting languages like Python or Ruby on Rails (RoR).

> JMeter is a useful tool for benchmarking your applications. It can be used to test applications' in-memory models, database models, and third-party APIs.


JMeter is an open-source platform for benchmarking, load testing, and stress testing your web applications. It can be used to test the performance of web applications in different ways including simulating user interactions with the application and measuring how long it takes to complete a task or process. This concludes our article on the topic of what is JMeter and we hope, we gave you an ample theoretical base for this software. We also recommend browsing through WeTest software solutions for similar testing services but for apps and game development.
