This Thursday, March 24th at 10am CET, I am happy to host a Webinar on Performance in agile environments. Especially eCommerce shops have embraced dev-ops on top of agile development to bring new features to their customers faster. Together with one of our german parnters, PiazzaBlu, we will show the challenges that agile development and dev-ops pose to [...]

Agile Development Practices have widely been adopted in R&D Organizations. A core component is Continuous Integration where code changes are continuously integrated and tested to achieve the goal of having “potential shippable code” at the end of every Sprint/Iteration. In order to verify code changes agile team members write Unit or Functional Tests that get [...]

I recently got engaged with a client who ran an increasing load test against their load-balanced application. I got engaged because they had a phenomenon they couldn’t explain – here is an excerpt of the email: We have a jBoss application with mySQL that runs stable in a load testing environment with let’s say 20 [...]

In the first and second post of this series I discussed benchmarking and different approaches towards optimization of web application. As already mentioned in the last post, as soon as you get used to working with Key Performance Indicators you will want to automatically monitor them. ShowSlow is a great example of how you can [...]

Watch the 7 Minute Walk-Through Video that guides you through the Integration described in this blog post. Load Testing has traditionally been done In-House with load-testing tools using machines in your test center to generate HTTP traffic against the application needing to be tested for high volume transactions. With agile development practices, shorter release cycles and [...]

A client of ours recently contacted me with the question: We use Keynote, WebPagetest and dynaTrace AJAX – but we get different results with these tools/services. WebPagetest tells us that our page is very slow – but dynaTrace on my local machine does not. What can be the problem here? What’s the difference? I took [...]

With more than 3 million downloads, Selenium is the world’s most popular functional testing framework. It allows web developers and QA professionals to automatically test how an application functions on multiple browsers, such as Firefox, Internet Explorer and Chrome and across operating systems, such as different versions of Windows and Mac OS. The FREE dynaTrace [...]

MicroFocus and dynaTrace recently announced “SilkPerformer Assurance” and with that announcement comes a tighter integration between MicroFocus’s Load Testing Tool SilkPerformer and dynaTrace’s Application Performance Management Solution for Load Testing. Enough has been said about the partnership in the actual press release. Now it is time to look behind the marketing curtain and explore the [...]

Microsoft released the next version of it’s Development IDE Visual Studio 2010. In fact – VS2010 is more than just an IDE to write applications. It also became a testing solution with the built-in Web-, Load- and functional testing capabilities. In a recent blog post and in a recent MSDN Webinar I demonstrated the capabilities [...]

I recently blogged about the Load Testing Capabilities of Visual Studio 2010 and the new extension interfaces that we from dynaTrace use to extend VS2010 Web- and Load-Testing to go beyond .NET and standard load-testing reports: VS2010 Load Testing for Distributed and Heterogeneous Applications powered by dynaTrace. Next week I am going to do a [...]
