Today, I attended a webinar of BlazeMeter. It was "How to Automatically and Simultaneously Test the Performance & Visual Appearance of Your App Under Load".
I have no experience of Load and Performance testing, and joined the webinar to learn them.
Presentation was excellent by two experts.
One interesting thing was Selenium was used for the performance testing during their presentations. I did not know it, and was excited about it.
After or while I reach to higher level in test automation, I would learn and practice Performance testing.
