What is JMeter?
The JMeter is a free and open-source software application to measure and test the performance of various HTTP response models. It is used in load testing tools, web-based applications, software performance analysis tools such as UFT (Unified Functional Tester), load generators, and Web Services Test Monitors (WSTM). JMeter helps in the development of scalable applications by providing an effective way to test their performance using simulated loads. Testing under different system configurations by using JMeter will help in identifying potential problems with components like caching or networking.
JMeter is an Apache Software Foundation project. It is a 100% pure Java application designed to load test functional behavior and measure performance. JMeter provides a powerful GUI for designing the test plan, including built-in support for HTTP web servers, LDAP directories, JDBC databases, servlets, and JSP pages.
JMeter includes the following features:
- A complete AJAX testing framework (JMF) to test both functional behaviors as well as the performance of AJAX applications
- An HTTP sampler optimized for testing REST-style Web services (JSR223) * Samplers that perform encryption testing using SSL or TLS protocols (HTTPS and FTPS).
JMeter is a performance testing application that can be used in monitoring and analyzing the quality of systems and networks by running test scripts. It provides a graphical user interface for assembling complicated performance tests to execute many different types of functional/load/stress tests.
Of course, it also has some limitations that you need to be aware of before jumping straight in. This article will cover all the basics, from JMeter’s history to its architecture and fail points. I’ll also show you how it’s deployed, with screenshots along the way! You’ll also learn how to deploy JMeter through Oracle Java 8 SE Runtime Environment on Windows 10.
Why Do We Use JMeter?
Why is it that every single person interested in performance testing has heard of JMeter? It’s an incredibly popular tool for load and stress testing websites and applications, but why is it so widely used? And what other options does the IT industry have for its load testing needs? Before long, you’ll know how to decide which tool will suit your needs the best. This informative web post will teach you about JMeter’s features, advantages, and disadvantages to help you find the right tool for your job.
The most popular software today is JMeter; not just because of its wide acceptance as a de facto standard in performance testing, but also because of its simplicity.
JMeter is a tool used to test the performance of web applications. It can be used to simulate a heavy load on a server, network, or application to test its performance.
JMeter is a Java application, so it can be used on any system with a Java Virtual Machine. JMeter can be used to test the performance of both static and dynamic resources, such as static files, Java servlets, CGI scripts, and dynamic resources that use Ajax.
JMeter can be used to simulate a heavy load on a server, network, or application to test its performance. For example, if you are testing a web application that will be visited by a large number of users, you can use JMeter to simulate the load. This will allow you to test the performance of the application under real-world conditions.
JMeter can also be used to test the performance of individual components of a web application. For example, you can use JMeter to test the performance of a particular servlet or JSP page.
JMeter can be used to test the performance of a web application under different conditions. For example, you can use JMeter to test the performance of a web application with different numbers of users, different bandwidths, different browser types
JMeter is an excellent tool for load testing and it can help you to improve the performance of your web applications.
JMeter is a popular open-source performance testing tool. It is widely used by developers and testers to measure the performance of their web applications.
There are many reasons why we use JMeter for performance testing. Some of the main reasons are:
- JMeter is easy to use and install.
- JMeter is free and open source.
- JMeter is highly extensible. There are many plugins available that can be used to extend JMeter’s functionality.
- JMeter can be used to test the performance of both web applications and web services.
- JMeter produces clear and comprehensive test results.
- JMeter can be used to simulate a heavy load on a web application or web service to test its scalability.
- JMeter can be used to test the performance of different database queries.
- JMeter can be integrated with other tools such as Selenium, Maven, and Jenkins.
- JMeter can be run in distributed mode to test the performance of web applications under heavy load.
- JMeter is a widely used tool and has a large community of users and developers who can provide support and help.
Advantages Of JMeter
- JMeter is a very powerful testing tool that provides a lot of features and flexibility.
- JMeter is an open-source tool, which is easily available and can be downloaded for free from the Apache JMeter website.
- JMeter is very easy to install and can be run on almost all platforms, including Windows, Linux, and Mac.
- JMeter is very user-friendly, and even those with no prior experience in performance testing can easily use it.
- JMeter provides a comprehensive set of reporting features, which can be used to generate both detailed and summary reports.
- JMeter can be used to test both static and dynamic resources, making it a very versatile tool.
- JMeter is highly extensible, and new features can be added by installing plugins.
Disadvantages Of JMeter
- JMeter is not a browser, and therefore cannot accurately simulate the behavior of a real user.
- JMeter is not a tool for functional testing, and cannot be used to test the functionality of an application.
- JMeter is not able to record actions performed in AJAX-based applications.
- JMeter is not able to handle complex authentication mechanisms, such as those based on Kerberos or N
Advantage of JMeter over LoadRunner
1) JMeter is an open-source tool while LoadRunner is a commercial tool. So, JMeter is cheaper than LoadRunner.
2) JMeter can be used for both functional and performance testing while LoadRunner can be used only for performance testing.
3) JMeter supports various protocols such as HTTP, HTTPS, FTP, SMTP, etc. while LoadRunner supports only a few protocols.
4) JMeter has a user-friendly GUI while LoadRunner has a command-line interface.
5) JMeter is easy to use and learn while LoadRunner is difficult to use and learn.
6) JMeter generates the test results in different formats such as HTML, XML, CSV, etc. while LoadRunner generates the test results in only one format.
7) JMeter can be used to test both static and dynamic resources while LoadRunner can be used to test only dynamic resources.
8) JMeter can be used to simulate a heavy load on a server, network, or object to test its strength or to analyze overall performance under different load types while LoadRunner can be used to test only the performance of an application under heavy loads.
How to Use JMeter?
To use JMeter, you need to first download the latest version from the Apache JMeter website. Once you have downloaded it, you can launch JMeter with a double click. The JMeter window will look something like this:
The JMeter window is divided into two main sections: the Tree View and the Workbench. The Tree View is where you will add and configure your test elements. The Workbench is where you can temporarily store test elements for easy access.
To create a test plan, you will first need to add a Thread Group. Right-click on the Test Plan and select Add > Threads (Users) > Thread Group.
A Thread Group represents a group of virtual users. Each Thread Group can be configured with its own set of properties.
Next, you will need to add a Sampler. A Sampler is used to perform a specific task like sending an HTTP request. To add a Sampler, right-click on the Thread Group and select Add > Sampler > HTTP Request.
The HTTP Request sampler will now be added to the Thread Group. You can configure the sampler by double-clicking on it.
JMeter will now send an HTTP request to the specified URL. You can view the results of the request in the View Results Tree listener.
To add a listener, right-click on the Thread Group and select Add > Listener > View Results Tree.
The View Results Tree listener will now be added to the Thread Group. You can view the results of the request by double-clicking on the listener.
To run the test, click on the Start button. JMeter
