How to load test OpenID/OAUTH

Performance testing scripts need to go through authentication in order to access target services with the right authorization. They also need to validate that the authentication servers are able to handle the target load. OpenID Connect (OIDC) has become a popular authentication and authorization protocol for securing web applications. This article will present the OIDC protocol and how to implement a JMeter script to performance test it.

OIDC Protocol

The OIDC protocol allows the application to rely on an authentication server to identify users accessing it. Usually the authentication server is linked to the enterprise access directory. In other words this protocol is aimed at providing Single Sign-On (SSO) solution for applications. Some big internet actors even allow users to authenticate on third party services through OIDC (for example authenticating on Gitlab using a google account).

Use JMeter to create a website crawler

The idea behind this blog post originated when we updated our documentation after the release of our new UI. We had to identify all links used in the OctoPerf website and update them from to With more than 250 blog posts at the time I'm writing this one, you can see how this could prove challenging. And of course the twist is that we also took this opportunity to reorganize the documentation so it's not as simple as a search and replace of the domain.

This got us thinking on ways to automate it, because a lot of third party links could also be broken and of course one of those ways is to use OctoPerf itself to execute JMeter tests that will report on all the broken links.

OctoPerf Spira Integration tutorial

We've recently been working with folks at Inflectra to develop an integration between Spira and OctoPerf. If you don't know about Inflectra and Spira they offer a very cool test management solution (among other things), you should check it out.

In this blog post we will highlight all the steps to follow in order to setup this integration. This way you'll be able to see the benefits of working with both tools in your organization.

Launch an OctoPerf test from Spira

Most of the following info has been taken from Spira's documentation page dedicated to OctoPerf.

Activate OctoPerf in Spira apps

The first step is to activate the OctoPerf integration from your Administration > SpiraApps page:


Troubleshoot your tests

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.

As a final note before we start, as much as you might want to jump to the relevant section of this guide, I strongly recommend you take a few minutes to read the next section since proper test preparation is essential to a strong error analysis later.

Analyze your load tests

OctoPerf's report engine provides many graphs to sort and presents test metrics in a comprehensive way. We've tried to improve it over the years so that you can access critical information very quickly. But requirements vary from one project to the other.

In this post we will look at how you can configure the report to show your preferred metrics, and also all the shortcuts you can take to achieve this goal.

The best example is the Report summary, it allows you to navigate between all the items in a few clicks:
