Behavior in Your Presentation

Tim Kadlec

Remember, one of the major benefits to proper use of web standards is being able to separate our content, presentation and behavior onto their own separate layers. I can also see how the line between behavior and presentation is a bit blurred already. I’ve spent some time lately playing around with the WebKit Nightly Build.

The Future of Performance Testing

Alex Podelko

Another major challenge is that continuous performance testing as part of the agile development lifecycle can’t be the traditional full-scale, realistic load/data/configuration load test in most practical cases (but it could – and should – be complemented by larger-scale tests; see, for example, my Context-Driven Performance Testing presentation). Following up my post Are Times still Good for Load Testing? , I decided to answer multiple comments here separately.

Are Times still Good for Load Testing?

Alex Podelko

In 2014 I was preparing a presentation about load testing tools and criteria for their selection. My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? Well, yes and no. I am not so upbeat as I was in 2014. If we speak about commercial load testing tools, we see rather a shrinking market and not too much innovation recently.

A Comprehensive Guide to Deal With XPath in Selenium
