Video: Real Stories of Load Testing Web 2.0 - Part 4

The fourth and final video of our Load Testing Web 2.0 series covers a very common difficulty in testing nearly any system, even older architectures; dependent calls external to the system under test. The concept of "stubbing" isn't anything new, to be honest I've been doing this for nearly 15 years and it's very common when there is a back-end mainframe required for the test. But now with Web 2.0 architectures, it seems that stray calls to a web service are eluding many testers and this is resulting in some nasty surprises from externally impacted vendors. Here is Part 4 of the series, "Real Stories of Load Testing Web 2.0: Load Testing with Web 2.0 External Calls (please try not to test stuff that's not yours)."

At the end of this video we mention another partner that built a professional "stubbing" solution.  Visit the iTKO LISA Virtualize page for more details.

Video: Real Stories of Load Testing Web 2.0 - Part 3

The third part in our Load Testing Web 2.0 series covers a not-so new concept of server-side data processing.  Don't be fooled into thinking you already know about server performance, because these new architectures are using client-like Javascript on the server; which is sometimes called reverse Javascript.  This video will describe how performance issues can sneak into this type of architecture and how even a simple component can result in serious latency and server-side resource overhead.  Here is Part 3 of the series, "Real Stories of Load Testing Web 2.0: Server-side Javascript Impacts (opposable thumbs not required)."

FREE Trial of Shunra's WAN emulation within HP LoadRunner

Who said good things don't come for free?  Recently I've spent much more time with our partners at Shunra Software...and I've learned more about networking and performance than I've ever imagined.  In celebration of HP Software Universe 2009 in Hamburg, Germany this week, they have posted a special FREE trial of the VE Desktop for HP Software.  WOW!  This is the integration that we introduced in version 9.5 of LoadRunner and Performance Center which has become extremely popular.  Here's a capture from the Shunra blog entry:









"In celebration of HP Software Universe in Hamburg, Germany Shunra is offering a free trial of WAN emulation within HP LoadRunner, VE Desktop for HP Software. You can use VE Desktop for HP Software to measure your application performance through a variety of emulated WAN conditions, including replication of production, mobile or theoretical networks. Click here to register for more information, receive download instructions, and get started making your application performance testing network-aware!"

  I guess this means: "Happy Holidays from Shunra"!  :smileyhappy:

Video: Real Stories of Load Testing Web 2.0 - Part 2

As the second part in this series we now, we highlight another common challenge we hear from customers testing new web applications; client-side performance. As you add these exciting and new components into the once-upon-a-time-very-thin browser, you'll find increased CPU and Memory resource utilization on the client.  Perhaps as no surprise, this can result in slower response times from page rendering or Java script processing overhead.  Here is Part 2 of the series, "Real Stories of Load Testing Web 2.0: Web 2.0 Components - Client-side Performance (Fat clients, you make the rockin' world go round)."

Video: Test Mobile Performance with Shunra (...can you hear me now?...now?)

Imagine yourself with 3 colleagues riding on an evening train from Berlin to Hamburg, and each of you have the same mobile service provider and similar phones. For 90 minutes, each of you are getting connected with different roaming providers, connection stability, sometimes with 3G and sometimes NOT!  (It boggles the mind, doesn't it!?)


Well, if you're lucky enough to be sitting next to a guru like David Berg from Shunra, you'll get the whole story on why this is happening.  In this brief, but highly valuable video interview we help to explain how the Shunra VE Desktop and HP LoadRunner can be used together to produce a robust load testing solution for mobile applications, complete with mobile WAN emulation.  Watch...and learn!

Also, David has an even more detailed explanation on his blog, which goes much deeper into the challenges of developing mobile applications that REALLY work well.

Video: Real Stories of Load Testing Web 2.0 - Part 1

We know many of you are finding great challenges with testing new web applications built with modern architectures and components like Silverlight, Flex, JavaFX and AJAX. So, Steve and I decided to put together a multi-segement video covering some of the top issues that make LoadRunner web testing much harder and more complex. Here is Part 1 of the series, "Real Stories of Load Testing Web 2.0: Impacts of WAN latency of Web 2.0 apps. (Mark Googles himself and Steve offers to go to Paris)."
