In this post we are going to look at WebSockets, specifically how JMeter can be used to test them. Web Sockets are not supported natively by JMeter but there are a couple of Plugins that you can use that work very nicely. One of them is called JMeter WebSocket Sampler by Maciej Zaleski and information on the library can be found here. The second and the one we will use for our post is also called JMeter WebSocket Sampler and is by Peter Doornbosch, more information on this Plugin can be found here.

Dynatrace is a cloud monitoring platform and is used by many organisations to measure the performance of their production systems and to set thresholds against which performance tolerance are measured. During testing Dynatrace can be used to monitor how the application under test responds during your performance tests as well as providing the capability to drill down into performance issues you may need to investigate.

You may have heard the term shift-left testing which is essentially moving the testing to an earlier stage in the project lifecycle, essentially the activity is moved to the left on the project timeline. The benefits of testing earlier have always been understood but not always happened when we consider performance testing which in some cases is still left until the very end of the delivery process.

The focus of OctoPerf 12.4 is on integrations, first in regards to creating test scripts through our new Postman import released a few weeks ago. Through postman we also open OctoPerf to swagger and open API imports. Microsoft Teams is also on the menu in terms of alerting before/after the tests, but the main dish is the backend listeners. Through these you can have our load generators send metrics to your own database in real time during the test.

In this blog post we are going to look at several JMeter Controllers, specifically: This is not an exhaustive list of controllers that JMeter offers but these once will give you a clear insight into how controllers are integral in defining load testing scenarios and how without them you will struggle to build complex and indicative load tests.

We’ve been working a lot behind the scenes for this release because we wanted to address the license sharing issue. Up until today it was only possible to ask us to share the license for you and sharing could only share every license you own. We had to completely refactor the way we handle licenses to allow you to decide on your own to share all or a fraction of your subscriptions. But that’s not all, we also worked on a VU validation with multiple iterations.

While the File Transfer Protocol is one of the original protocols used in the early adoption of the internet it remains a fundamental part of modern computer networks. In this post we will look at the way the JMeter can support you in performance testing FTP and SFTP.

Performance Testing coverage needs to be defined from the application under tests functional requirements and this does not change regardless of whether you are following an Agile or a more Planned approach.

Preparing resilient tests can be a challenging process when you do not know where to start. We will cover this in this guide, from the virtual user validation to smoke testing. And then analyzing the most common errors and how to fix them. Note that we also recommend reading this other guide, it can greatly help understand the analysis and report engine of OctoPerf.
