Typically, load testing will have pre-defined load limits, so as not to cause the system to fail. Stress testing and load testing are related, but the goal of stress testing is to increase the amount of load until the system fails, or performance is degraded. Simulated load is applied, typically starting at lower levels, and slowly increasing load over time, in order to gauge performance under load and how the overall system responds. Load testing can be executed against various systems, websites, web apps, APIs, and more. Load and stress testing are just subsets, or types, of the performance tests within the performance testing family. Even more, those terms are sometimes used interchangeably. When we generally think about performance testing, or when the term performance testing is used, what usually comes to mind is load testing. Load Testing with JMeter-What’s The Difference? Compared to SaaS-based load testing tools, this may take some additional time and resources. For example, you must have the latest version of Java installed and must meet the minimum system requirements to be able to use JMeter. JMeter is a Java-based desktop application, so in order to begin to use JMeter, there are various prerequisites that you must meet before you can start your performance test. It is important to note that JMeter is not a browser, meaning it works just at the protocol level, and does not support all the actions made by the client or user, such as rendering JavaScript.ĭespite this limitation, JMeter does provide a workaround for these issues, by offering features and elements like cache manager, cookie manager, and header manager, which allows JMeter the ability to act and perform more like a real browser would. From the data gathered and created reports, users can observe application behavior and performance bottlenecks, offering insight into where application improvements need to be made. The server response data is then collected, and the statistical data is displayed visually for users in the form of charts and reports.

We will look at how JMeter works, how to carry out performance tests, with JMeter, alternatives to JMeter, and much more.Īt a basic level, JMeter works by simulating visitors to your application or service by allowing users to create and send HTTP (Hypertext Transfer Protocol) requests to the server. This guide will set out to cover all the various aspects, benefits, features, and disadvantages of JMeter.

Compared to other performance and load testing tools and solutions that you see in the market today, JMeter was one of the earliest tools introduced to the performance testing market, which is why it is still popular and widely used to this day.

JMeter is an extremely popular open-source Java-based performance testing tool for running protocol-based load tests against various web and software services, APIs (SOAP and REST), web applications, and other web services. If you are new to performance testing, you might be asking yourself what is JMeter? And how does JMeter work?

A quick search for performance testing tools will uncover many free, open-source, and commercial-based options.

If your web applications, sites, or APIs are going to be used by large numbers of users, you need to know how they are going to stand up to peak traffic or extended periods of sustained high traffic. For example, if you want to test the endpoint, the host name is testing is an extremely important aspect of the software and application development life cycle. In the file, set the value of the HTTPSampler.domain node to the host name of your endpoint. This script simulates a load test of five virtual users that simultaneously access a web endpoint, and takes 2 minutes to complete.

Open SampleTest.jmx in a text editor and paste the following code snippet in the file: If you already have a script, you can skip to Create a load test.Ĭreate a SampleTest.jmx file on your local machine: touch SampleTest.jmx For more information about creating an Apache JMeter script, see Getting started with Apache JMeter. If you don't have an existing Apache JMeter script, you'll create a sample script to load test a single web application endpoint.
