Simulation: JMeter can pretend various users with the same threads, generate heavy load against web application under test.Testing, load testing, and Functional Testing, etc.Support various testing approach: J Meter supports distinct testing proposition like Distributed t.JMeter uses a text editor to create a test plan and supplies in XML format. Write your test: Using plugins, we can write our test case to extend the testing process.It is hugely flexible and capable of loading the performance test in distinct server types: Web – HTTP, HTTPS, SOAP, Database via JDBC, LDAP, JMS, Mail – POP3. Platform independent: However, it is entirely a Java-based desktop application.It is straightforward and easy to use, and users get friendly very soon with it. User – friendly GUI: JMeter has natural GUI.

Open source application: JMeter is a free of cost open source application which maintains users or developers to use the source code for other enlargement or variation purpose.There are some important features of JMeter which are given below: Stress Test: This test tries to break the system by destroying its resources. Load Test: This test is useful for regulating and introducing the system under the top load it was trained to work under the process. Very fast, it also points the change need to be made before the ultimately Application goes into production. Performance Test: This test generates the best possible performance of the system or application under a configuration of infrastructure. Let's see an example: how the “ Gmail" supporting server will perform when numbers of users access the Gmail account at the same time – basically they have to do performance testing holding performance testing tools like JMeter, LoadRunner, etc.īefore understanding Overview of JMeter, let see these three testing approach, It also can be used as a unit testing tool for JDBC database connection, FTP, LDAP, Web services, JMS, HTTP any many moreIt runs on any environment accepting Java Virtual Machine, e.g., Windows, Linux, Mac, etc.

It is developed in Java and developed by Apache software foundation. Its latest version is 5.1 which was released on and, its first version was released in 1998. It can use as a load testing tool for analyzing and determining the performance of a variety of services with a focus on web applications.

To do this, right-click on Test Plan -> Add -> Listener -> Backend Listener:JMeter is a framework of Apache.

But before that, to follow our test in real time, we will add the Backend Listener element to enable live monitoring of the progress of the test with Grafana ( ).

So, let's use best practices directly and run our test from the command line in CLI mode (also called Non-GUI mode in JMeter).

NoteĪn easy and quick solution to monitor JMeter can be to use the Servers Performance Monitoring plugin from the JMeter Plugins ( ). Note that this is not specific to JMeter but should be done regardless of the tool you use. This ensures that if we get bad response times, the cause is the application being tested and not JMeter.

When load testing, it is advisable to monitor the injectors (servers where JMeter runs) at least during the first test at full load to validate the correct behavior of the injectors.

We could run our load test directly from the JMeter GUI, but this is not recommended as it would not be optimal for performances of injection (although, in our case, with only 10 users, it shouldn't be a problem).

This point will be discussed deeply in Chapter 2, JMeter Overview. Several strategies for setting the load test exists. By the end of this book, you'll know all that's needed to perform comprehensive load testing on your applications by using all the best practices and features of JMeter.įigure 1.27: Load test parameters Caution You'll discover ways to use the eco-system of JMeter to integrate new protocols, enrich its monitoring, and leverage its power through the use of the cloud.

Finally, you'll see how to integrate JMeter into the DevOps approach and create professional reports.

You'll also explore the different protocols offered by JMeter through various real-world examples. You'll learn the best practices that you must follow while designing test cases. This book is written by JMeter developers and begins by discussing the whole process, including recording a script, setting it up, and launching it, enabling you to almost immediately start load testing. By leveraging the features and capabilities of JMeter, you can perform extensive load testing and fix issues in your application before they become problematic. One popular open source tool for load testing is JMeter. Load tests help identify the maximum number of requests a software system can handle.
