JMeter is a free open-source tool used for analyzing and measuring the performance of applications, different software services, and websites. Written entirely in Java, JMeter can be used to conduct performance, load, and functional testing of many different web applications and server protocols.
Apache JMeter can simulate heavy loads on a server by creating multiple virtual users, also known as concurrent users, simultaneously. JMeter can also be used to test both web and FTP applications, SOAP and REST APIs, as well as email protocols like SMTP, POP3, IMAP and much more.
Before using JMeter, you must ensure that a current version of Java is installed on your system. The latest version requires Java 8 or higher. It is best practice to always use the most current version of JMeter as the software is constantly being improved and updated.
Note: JMeter can be started in three different modes. For the purposes of this JMeter load testing tutorial, we will focus on starting in GUI mode.
No credit card. No contract.
Once JMeter has completely loaded, you can begin the process of creating the test plan. The test plan includes all of the elements that go into building the test plan. We will talk more about these elements in the coming sections.
JMeter also allows users to build test plans from templates that contain the necessary test elements. There are numerous options available depending on your JMeter load testing requirements. Listed below are just a few of the options that are available to users.
Samplers are the actual requests to the server. For example, HTTP samplers are used for a website, application, or API load test. Other Samplers include FTP, SMTP, Java, JDBC, and SOAP requests. To create a request Sampler, follow the steps below. For the purposes of this JMeter load testing tutorial, we will add an HTTP sampler.
Once you have finished configuring your Thread Group, Samplers, and Listeners, the test is ready to run. There are a couple of different ways to run, or execute, a load test.
As an open-source load testing tool, JMeter allows performance testers and engineers to carry out fairly basic, straightforward test scenarios. However, it has its limitations. If you are looking to generate large-scale tests, in real browsers, from multiple geo-locations, you need a more modern load testing solution that can handle these real-world scenarios. LoadView is a cloud-based performance testing solution that provides developers the functionality to test websites, APIs and web services, web applications, Postman Collections, and JMeter scripts – all from single interface. No more worrying about hardware upgrades or managing load generators. LoadView removes these time-consuming, burdensome, and costly tasks so developers and engineers can focus on testing.
