Centralised Testing Functions – Oversight and Governance

I’ve been working on a project over in Sweden, and have found it unlike anything I’ve ever seen before. Sadly, this is for all too familiar reasons. I work for an organisation with a small performance testing function centralised across all the projects that can be conjured up. As a result, there are often a […]

Python Functions

Declaration of functions in Python is nice and simple. def my_function(): print(“Hello From My Function!”) The call is also uncomplicated my_function() With Arguments def sum_two_numbers(a, b): return a + b sum_two_numbers(10,8)

Extending Loadrunner Scripts with C – Function Library #1.2

I have now left the Cardiff JMeter role, and returned to Loadrunner work, this time in Dublin. With every new position I find myself re-invigorated to learn new things, update old code and write some articles for the site. I have a lot of ideas in my head at the moment, but my shower thoughts […]

Jumping Ahead with JMeter

A new article in the dev diary describes how I’ve gone about creating a fully automated performance test suite using jmeter for my latest clients. A further article will shortly appear here, although my concept of shortly may be somewhat different to most. In any case I have plans to document the process of constructing […]

String Manipulation with VBA

As a performance tester, most data arrives at me in a spreadsheet, or an enormous text file with little or no delimitation. The previous article showed how to parse across columns and down rows to gather data. Excel has a number of built in functions to manipulate that data before outputting it for us. Functions […]

Excel as an IDE

I’ve often found, especially when starting at a new client, that real development tools aren’t provided for testers (even automation testers) as standard and have to be requested from the helpdesk. This can take a week or longer to sort out, depending on efficiency. It’s worse in financial institutions who seem to think Admin rights […]

Performance Testing – 4 Questions (an approach)

I’ve been asked to give a talk to some of our off-shore developers. They’re sitting through a workshop on just about everything related to the client environment, and I’m talking for 15 minutes about performance testing with Loadrunner against web-baed sales flows. I thought about winging it, but the manager has asked for a powerpoint […]

Loadrunner misses extra resources

Recently, I’ve encountered an issue with an AUT where it crashes VUgen during the generation stage of a recording session. Now I’m a big fan of record-edit-playback. I find the recording and generation logs hugely useful and I find that recording is the easiest and quickest way to get a view of the application. I […]

Extending Loadrunner Scripts with C – Function Library #1.1

Actually, this is more like 1.1. In as much as it ties into the previous post. I was blogging about building audit logs and data files via an “audit” script. That’s what I call them, not sure if there’s a full blown technical name but I use them to verify, validate and build data to […]

So what have you been doing?

It’s been a long time since I had the time and inclination to update the site. Partly because I’ve been busy working and partly because I was hideously aware that the next stage for the site was complicated and not exactly in my wheelhouse. I can code, clearly, since I automate everything and work as […]
