I had an interesting conversation with our Test Automation team lead Stefan – who Andi interviewed for our “Eating our own Dog Food ” article – on his experiences with the willingness of developers to write performance tests.
I asked a provocative question: do developers really want to write them in the first place? First he [...]

I sat together with Stefan Frandl, Test Automation Lead in dynaTrace’s R&D Lab in Linz, Austria to discuss how dynaTrace does Continuous APM in Development. Obviously dynaTrace takes performance very serious as we preach to our clients that Continuous Application Performance Management is a critical component across the Application Lifecycle. The earlier in the Lifecycle [...]

I’ve recently been working with several clients to analyze their web site performance with the dynaTrace AJAX Edition. Based on our findings their JavaScript code, usage of 3rd party frameworks, use of AJAX, embedded objects and caching strategies have been changed over multiple iterations. After each iteration it is good practice to verify if the [...]

On a recent project I had to call Java REST services from a .NET Client. Several problems came up – ranging from authentication to hidden performance issues. I want to share my lessons learned and encourage you to share your own opinions and experiences on this topic.
The Context: REST to automate analysis processes in Continuous [...]

Selenium is a free Web Application Testing System. It gained lots of popularity since it is available. It’s integration to FireFox – which allows instant record/replay as well as the scripting option - makes it a great tool for functional web testing.
BrowserMob on the other side leverages Selenium by providing an automated load-testing environment for Selenium scripts all [...]

Scenario: different test types target the same test machine
For smaller software projects – where deployment and configuration of the application to test is easy – you often find separate installations for individual testers or test types. This allows every tester to work against an installation without impacting other test activities.
For large enterprise software projects, however, it’s [...]

Functional Testing has always been an activity done by Test Engineers using Functional Testing tools like QTP from HP/Mercury, SilkTest from Borland/Segue, Functional Tester from IBM/Rational, …
But time is changing – so is Functional Testing – and the things you can do with it. In this article I talk about

The Past – Functional Testing done [...]

I recently gave  presentations on Performance Management as part of Continuous Integration at QCon London and JAX in Wiesbaden. While I got the feedback that this definitely makes sense, a lot of people said they do not know how to put it into practice.  Therefore I will provide a short implementation guide on how to [...]

Continuous Integration has become a well established practice in todays modern software development. Especially for enterprise applications – that face the architectural challenge of dealing with a highly distributed and heterogeneous environments - its more necessary than ever to establish and enforce these kinds of practices.
Aren’t Automatic Builds, Unit- and Integration Tests enough?
How often have you been facing [...]
