By now you've probably heard of watir or Web Application Testing In Ruby, a great automation framework which supports Microsoft Internet Explorer, and recently came in at number 3 as a popular oss tool on this blog.

Recently had a requirement to construct a LoadRunner harness that could sftp files (over ssh) to and from remote servers. As some of the harnesses were already written in Java (for loading of JMS queues) it made sense to use a Java Vuser to achieve the result required.
A work colleague ...

Recently I noticed some discussion in the watir user group about trying to capture screenshots when running automated tests.
For such a simple requirement, it's frustrating that solutions available either cost money (such as the purchase of SnagIt) or are a tad complicated in implementation requiring the installation of some out ...

This is a short post on how to establish JDBC connectivity to a MySQL database when using the Java Vuser type within LoadRunner. Stuart describes a situation in which you might want to do this here. I'm not sure why but the example code is missing from his site, so ...

Another post for my fading memory, how to install the GD libraries for your Leopard Apache installation running PHP 5.2.5. I will be using these libraries in a forthcoming blog about the use of 'sparklines' to present complex performance monitoring data.

If you've been using a Macbook Pro or similar for some time, you'll find that their batteries need tender love and care, if they are to go the distance. According to Apple, I fit into the 'ideal use' category as I regularly use my notebook on the 1+ hour daily ...

In working with SiteScope of late, I've found that it doesn't always collect performance metrics the way I want to. More importantly, it can often turn a simple monitoring activity into a complex disaster. Take monitoring via JMX for example. In SiteScope, it has a rather complicated (and sometimes broken) ...

Ever been on a client site and stuck with 1024 x 768?
I remember when even that was a dream, but after you get used to widescreen dual VGA in your own environment, weaning yourself off this can be a challenge. If you believe Microsoft research, dual screen users "never ...

After getting nowhere with lack luster HP support, I turned to the power of the Open Source community and got a very simple script up and running to remotely monitor Weblogic JVM Performance and JMS queues using JMX and JRuby.
Despite having some initial issues with the code, the author of ...

I quite literally stole this idea from Charlie at PerformanceEngineering in which he posted a response to a challenge by Dmitry on how to get regular expressions up and running within LoadRunner.
I'm a huge fan of regex, and thanks to these guys, now have a way of implementing at least ...

HP LoadRunner Analysis is a free tool right? Well, maybe not "free, as in free beer", but you can certainly install the trial version of LoadRunner 9.x, and Analysis does not appear to be time limited.
All right, I realise that the Controller is time limited, so how do you go ...

If you've ever had to write lots of LoadRunner scripts you'll probably be interested in this snippet of code. Imagine you're in a situation where you need to produce many LoadRunner scripts each with multiple actions. Normally, once you've got all your custom correlations down pat (I hate correlation studio ...

A colleague asked me the other day if it was possible to setup a workstation with just LoadRunner installed and have it automatically carry out a typical user transaction to determine the 'health' of the target server. After explaining to him that it would be a clunky approach at best, ...

I currently have a mobile broadband account (HSDPA) provided by three.com.au, and after a hexy surcharge from the previous month when exceeding my limit, thought it would be prudent to build a dashboard widget that tracks my monthly bandwidth usage.
