JMeter 5.6.3

With the recent release of JMeter 5.6.3, you now have the option to select this version when running new JMeter tests on RedLine13. In addition to several bug fixes, there are a number of minor improvements and dependency upgrades as well. This release of JMeter is compiled with Java 17 and marks the beginning of the transition to that version of the platform. Future major releases of JMeter will require Java 17. Bug Fixes There areRead More →

k6 vs JMeter

When it comes to load testing, there are two platforms which must be mentioned.  k6 and JMeter have established themselves as the de facto standards in the performance testing space. In this article, we will compare and contrast the features of each, to help you better decide which technology is right for you. A Brief History JMeter was introduced more than 20 years ago, and in that time has become one of the most utilized performanceRead More →

Getting Started with k6 Load Tests on RedLine13

As one of the five major test types supported on our platform, RedLine13 offers the ability to run your k6 load tests in the cloud. Tests are defined in k6 using the JavaScript syntax, centered around simplicity and extensibility. It is a developer-centric performance testing tool that affords scalability to test designers for scripting, execution, and analysis of load tests. Since it was introduced, k6 has steadily risen in popularity to become one of the deRead More →

Dynamic Requests from Code

One of the challenges that often presents itself when testing modern web applications is the ubiquitous reliance on asynchronous requests embedded in the user experience. It is possible to replicate most of these actions purely using request samplers in JMeter. However, there are many cases where it is desirable to get the response for a simple task – especially where it helps us attain our main test objectives. There may also be a need to requestRead More →

Did you miss the demo? Read these: See the Demo Live Live demo of ChatGPT augmenting JMeter testing. The demo will include creating test plan steps with ChatGPT and using ChatGPT to analyze JMeter test results. In addition, you will see how ChatGPT can be used to compare two or more load tests.

User Interview - Janesh Kodikara

In this series, we interview RedLine13 users. Janesh talks about what he likes best about load testing, biggest challenges and advice for someone new to load testing. Why did you get into load testing?  I initially got into load testing because I recognized its critical role in ensuring the reliability and performance of software applications, a key aspect of software quality assurance.  How did you learn about load testing?  I learned about load testing during myRead More →

JMeter Assertions to Control Test Flow

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

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

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

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 →
