Performance Testing, Artificial Intelligence and Machine Learning

We are going to look at how performance testing can work hand in hand with Artificial Intelligence and Machine Learning:

We will look at how we can use data gathered from performance test scenarios during execution to determine what functionality and what concurrent volumes and load profiles we should be testing.
We will use very simple mathematical models to do this in conjunction with a very simple database model with several manual steps to simulate the machine learning.

As there are many Artificial Intelligence solutions to choose from and for the purposes of this post this is the easiest way to discuss the principles of Artificial Intelligence working with performance testing rather than discussing a particular framework.

Angular Performance Optimization - OnPush Change Detection

In our previous blog post we saw why calling functions in Angular template expressions is bad practice and can have huge performance impact on your application.

Now it's time to take a look at Angular ChangeDetectionStrategy and see how it can help us improve the performances of our Angular applications.

Angular Performance Optimization - No Call Expression

At OctoPerf we created a load testing web application using Angular for the frontend.

The application features IDE capabilities (like IntelliJ Idea or VSCode) to create load testing scripts:

We faced several performance issues while creating such a complex web application. This blog post is the first of a series dedicated to common Angular performance issues and how to solve them.

OctoPerf's new UI - Analysis changes

This article is the last in a series of overviews of our new UI. You can find the others here:

This time we will dive into the changes we've made in the analysis.

Uncommon Performance Testing

In this blog post we are going to look at some of the uncommon performance tests. By this we mean those scenarios that are not what we believe are commonly executed but those that are run periodically at best.

These uncommon scenarios should not necessarily take priority over the more common performance scenarios. They do add value by stressing parts of your application under test that may be missed by the more conventional tests.

We will discuss each scenario in turn and look at the benefits and some of the difficulties you may experience in designing these scenarios. We will also take time to give examples of when these scenarios would be useful.
