JMeter Assertions to Control Test Flow

JMeter Assertions to Control Test Flow

2023-10-12

Creating a JMeter performance test plan often involves simulating a series of requests.  Whether we intend to run one request sometimes depends on if the previous request was successful – in essence creating a branched-logic flow.  In this brief post, we will show you how to use JMeter assertions to control the flow of your test. Conditional Test Flow In a previous post, we covered all the different types of JMeter assertions that are available.  Here,Read More →

The JMeter Random Controller vs Random Order Controller

The JMeter Random Controller vs Random Order Controller

2023-10-02

When it comes to introducing random variability within test plan execution, there are two similarly named plugins for JMeter which are up to the task.  Each of these applies randomization to your tests, but in different ways.  In this brief post, we will analyze the similarities and differences between the JMeter Random Controller and the Random Order Controller. The Random Controller is one of two built-in logical controllers for randomization. When you add an instance ofRead More →

All the Ways to Compare JMeter Load Tests

All the Ways to Compare JMeter Load Tests

2023-09-11

In this post, we will review and compare the different approaches available for comparing two or more JMeter load tests. This is a task we are frequently asked, and the answer often depends ultimately on the requirements of your project. Some of these methods may be used to generate one-off comparisons, while others comprise a system of data collection for comparing many tests over extended runs. We will briefly explain the premise for each of theseRead More →

Using ChatGPT to Analyze JMeter Load Test Results

Using ChatGPT to Analyze JMeter Load Test Results

2023-09-05

In a previous post we discussed how ChatGPT could be used to assist and partially automate JMeter test plan creation. In this post, we will explore how ChatGPT can be used to help analyze and compare JMeter load test results. I’d like to take a more illustrative approach showing the types of tasks that ChatGPT is good at solving. This will give you a better idea of how to structure queries and get the most outRead More →

Compare JMeter Test Results

Compare JMeter Test Results with the JMeter Merge Results Plugin

2023-08-30

A common approach to load testing often involves running a series of load tests to ascertain the performance of a target test application. The question that is sometimes asked is how to compare JMeter test results from two or more runs of a similar JMeter test on the same graph. In this article we will show you how to compare the results of two separate load tests using the Merge Results plugin. In a previous postRead More →

Overlooked JMeter Plugins You May Not Know About

Overlooked JMeter Plugins You May Want to Know About

2023-08-24

We previously talked about the Top 10 JMeter Plugins and the versatility of JMeter through the use of plugins. We overviewed the top ten most popular plugins for JMeter that test designers are using today. In this follow-on post we’ll overview some overlooked JMeter plugins – some of which you may want to know about. Results and Reporting Synthesis Report – Using this plugin, you can create a separate *.JTL file that contains filtered results from yourRead More →

ChatGPT Assisted JMeter Load Testing

ChatGPT Assisted JMeter Load Testing

2023-08-15

There has been a lot of excitement surrounding large language models (LLMs) and especially ChatGPT made available by OpenAI. Heralded as a paradigm in making powerful AI capabilities widely accessible, the GPT-3.5 and GPT-4 models behind the ChatGPT interface continue to find uses in business, data science, linguistics, and writing that did not exist in the short time before their release. In this article, we will illustrate how the LLM behind ChatGPT can be leveraged toRead More →

TCP/IP Testing using the JMeter TCP Sampler

TCP/IP Testing using the JMeter TCP Sampler

2023-07-28

While the primary focus of JMeter is on application-level HTTP-based testing, it also supports protocol-level TCP/IP testing using the TCP sampler.  In this post, we will review the basic setup of the TCP Sampler, and how to use it in your JMeter tests. This component allows JMeter testers to simulate network-level protocols and evaluate the performance of systems that rely on TCP/IP messaging, but not necessarily HTTP calls. Examples of these include internet of things (IoT)Read More →

JMeter 5.6.2

JMeter 5.6.2 – Security Fix Included

2023-07-25

RedLine13 now supports JMeter 5.6.2 as it has been made a generally available release.  You can find all the updates in the Release Notes for JMeter, but we have highlighted a few important changes below: Multiple Security Fixes There are multiple security fixes that have been released between versions 5.6 and 5.6.2 of JMeter.  One particular security vulnerability in JMeter version 5.5 was recently discovered and described as a critical issue.  In exploiting this, it couldRead More →

How to Select the Best JMeter Thread Group

How to Select the Best JMeter Thread Group

2023-07-17

In this article, we will describe when it might be best to use each type of JMeter Thread Group.  Examples of test plan elements that a thread group may contain include HTTP samplers, logical preprocessors and postprocessors, timers, and many other components within a test plan.  The most elementary component is the basic Thread Group, which is a simple container for requests and other operations in many JMeter tests. Types of JMeter Thread Groups JMeter offersRead More →
