Ramping VUs in k6

When creating a load test, it is sometimes desirable to control how the rate of requests are scaled over time. k6 provides this behavior through the ramping-vus executor, which allows gradual scaling of virtual users over a specified duration. This enables realistic simulations of user traffic patterns as expected in real-world use cases. In this brief post, we will outline the basics of using this feature in k6. Example Script of Ramping VUs The following k6Read More →

Speak the Lingo using Load Testing Terms

Load testing is a niche skill within the large trade of quality assurance. With any trade, being able to communicate effectively the nuances and concepts used is essential. In this brief post, we will go over several definitions that will allow you to speak the lingo using load testing terms. Below we have divided these into categories for better organization: General load testing terms Load generator server – Each load test is run on one orRead More →

Capacity Reservations for Large Load Tests

Scalability is one of the greatest strengths of using a cloud-based architecture.  However, there are occasionally limitations to how quickly we can scale. This is especially true for high volume load testing.  In these scenarios, we need to instantaneously scale a practically nonexistent cloud architecture to our maximum desired size.  It is not always guaranteed that cloud providers like AWS will have these resources idle and waiting in the necessary quantities.  In this post we willRead More →

Steps to JMeter Scaling

We have been asked some questions on how JMeter scaling works. First a little background and then we’ll talk about how you can do it.  If you are running JMeter locally and you need to simulate a larger number of concurrent users, there are limitations on the number of concurrent users you can run. It depends on the CPU and memory of the machine. And running a large test on a single machine can quickly hitRead More →

Introduction We recently had the opportunity to speak with the developers at Technocrat about integrating load testing into their workflow. Their specific challenge was writing JMeter tests and scaling them in the cloud. Our conversation with their team provided us with greater insight into how companies like Technocrat use and draw value from load testing, and we wanted to pass those insights onto the testing community.

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing True story, but leaving out a few company specific details.  One of my first entries into managing larger teams was a project which had 40-50 developers and the middleware needed to support thousands of transactions per second.  The system was built with the work of a great team and the expertise of one amazing project manager, but we needed to start load testing. Realize this was circa 2004, so pre-cloud.Read More →
