Sharing variables between Virtual Users

Variables, may they be constant or dynamic, are an essential part of load testing.

We already learned how to manipulate these values by extracting and re-injecting them inside one Virtual User.

But what if we need to share these values between several Virtual Users ?

In this blog post, I will show you just how to do that, using the MQ technology.

What is AMQP ?

Advanced Message Queuing Protocol (AMPQ) is an open standard protocol that allows messages exchanges between different systems.

In practice, it lets you store values in queues, values that can be retrieved later by simple calls.

Install OctoPerf in your company

We have come a long way since the original release of the OctoPerf On-Premise Infra 30 months ago. We have added so many features since then that it felt important to regroup them in this blog post to highlight how easy it has become to install and manage your own OctoPerf server.

I will refer to our documentation a lot because all of these features are detailed there. But documentation can sometimes make the decision process more difficult just because of the sheer amount of information it gives. That's why the purpose of this post is to follow a simple use case and highlight all the possibilities on each step of the way.

Test mobile native applications with OctoPerf

As mobility has been the trend these past years, all the users coming to a website do so from many different devices. OctoPerf allows you to simulate traffic to your website, but it also allows to simulate this kind of multi-device traffic.

That being said, to take advantage of OctoPerf possibilities, you might need to import several different user journeys. Because a mobile user is very likely to deal with a different version of the application. Thus if you record only one user journey from a computer's browser and use it for your tests, they may not be realistic.

Browser based mobile apps

To record the traffic from a mobile application, you have several options. For browser based apps, you can record them from Chrome or firefox and just use the dev tools to switch the user agent:

Native apps are a bit more complex to get by.

Let's see what is required step by step to record such an application.
