What are the different types of load testing scenarios? Leandro Melendez (aka Señor Performo) discusses some of the most common types as well as some best practices for load testing.

In June 2020, the Dutch government the "coronalijn", a telephone hotline that any resident could call to schedule a COVID-19 test. The system struggled after a whopping 323,000 people called it, a quarter of whom didn't even call for a test. How does fear affect performance outcomes, and what can we do about it as performance engineers?  

What is the difference between browser and protocol automation? Guest flooder Leandro Melendez, aka Señor Performo, discusses the advantages and disadvantages of each one, especially with regard to load testing.  

Load testing video streaming can be technically difficult compared to API load testing because there are metrics other than response time that you need to consider. In this video, Nicole shows how to load test video streaming using JMeter.

In the last video, Nicole discussed how to get started with using test data from a file in Flood Element, but what if you want to make sure that only unique data is used in your load test? You can do this by using a unique variable that identifies every browser instance in your load test and tying the user data to it.

Adding test data to your load testing scripts is a great way to make your scripts more realistic. Luckily, it's pretty straightforward to use test data in Flood Element, a browser-based load testing tool.  

In this Flood Element tutorial, Nicole shows the steps required to install Element, including dependencies it requires. Flood Element is an open-source browser-based load testing tool created by Tricentis Flood.  

How do you load test a native mobile app? Nicole discusses the general approach to mobile load testing, what a device farm is, and why a device farm isn't necessary for load testing. She also discusses the best mobile load testing tools to use.

When it comes to software testing, the debate of Puppeteer vs Selenium is a hot one. Nicole tackles it here to determine which one is better for load testing in particular. Spoiler: The answer is still "it depends".

Nicole talks about how to install the JMeter Plugin Manager as well as other plugins, what the best JMeter plugins are, and why you need them. JMeter is an open-source load testing tool that is already robust, but there are some fantastic plugins that have been developed for it that you might want to use in your next load test.

What's the difference between load testing and stress testing? When should you choose to run a load test on your application, and when is a stress test more appropriate? Well, it's all in the intention.

What is the meaning of concurrent users in performance testing? You might have seen concurrent users in JMeter or other tools, but what does it mean and how can you use the term properly?
