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.

Looking at the uses of JMeter Timers

Timers in JMeter are incredibly important when it comes to the balance and pace of your performance tests, we are going to look at the Timers that ship with the standard JMeter installation in this Blog post but there are others that are available as a Plugin and hopefully this post will encourage you to investigate these further.

The timers that we will discuss are:

The basics of Simple Performance Testing

You don’t have to performance test if you are not bothered about the performance of your application; this is the only reason, if you are bothered and you want to make sure your customers get the best possible experience then it is wise to do some.

You have probably experienced poor application performance if you do any form of online shopping, many web sites are unable to handle the volumes of load and concurrency they see on their eCommerce platforms at peak times sure as Black Friday or Christmas.

Some even have to introduce a queuing system to throttle the load on their systems which leads to customer complaints and a poor reputation.

In this Blog Post we are going to look at some of the things you can do, that are not overly complicated, to reduce the risk of poor performance on your applications; basically, the simplest approach to performance testing we can think of.

Clearly, we would always recommend you invest a fair proportion of your QA effort to performance testing but if that is not something you wish to do then these simple things could be the difference between an application that can cope with high seasonal demands and one that does not.

This is therefore our guide to a simple performance test.

Angular: How to Use Multiple Themes with Material?

This blog post is a tutorial on how to use multiple themes for an Angular11+ application with Material Design.

We start from scratch by creating a new project and configuring the themes. Then we add a sample Card component to see what the themes look like and create a button to switch between Light and Dark themes.

Finally, we discuss two solutions in order to apply a theme to the application body and to a custom component:

Performance Regression Testing

Regression Testing, as all Quality Assurance professionals know, is ensuring that previously developed and tested software continues to operate after a change.

Performance Regression being a subset of regression testing as a discipline is therefore ensuring that previously developed and tested continues to meet its performance criteria after a change.

There are subtle differences in the way that performance regression testing is approached when compared with functional regression testing, and we will look to explore these in this Blog Post.

A suitable performance regression strategy can provide huge benefits to your organisation, and we will look that these benefits as well as how to accomplish them.

Once you have a performance regression test suite it is important that it constantly evolves and is not left to become outdated and eventually obsolete, it must be maintained as we will discuss this also, but the benefits of a well-maintained regression pack will exceed the effort required to maintain them.
