Python Basics

The absolute basics: Strings print(“Goodbye, World!”) x = “string value” print (x) Integers myint = 7 print(myint) Floats myfloat = 7.0 print(myfloat) myfloat = float(7) print(myfloat)

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 […]

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 […]

Dev Diary

There’s a link to the dev diary over there on the right, currently amongst the links to hosts and wordpress themes. I’ll be adding more relevant content as I find it. I’ve added a few days of diary regarding test stubs, vbs and vb6. It’s coming along nicely. The dev diary will be much more […]

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 […]

New Development Project – Loadrunner Scheduler

Amongst all the other tasks I have with performance testing and automating on client sites, and sleeping, I once developed an excel-based scheduler for Loadrunner.

Extending Loadrunner Scripts with C – Function Library

So, I’m working at a new client, back doing the Loadrunner thing. One of the nice things about that is I get to re-use and refine code I’ve written previously for other clients. This article is going to contain some of these code snippets that I’ve used time and time again. I’ve re-visited this code […]

A failed web_find is not always an error

I’ve been working in Lithuania for the last 3 months. It’s cold over here. To keep warm (and paid), I’ve been writing some loadrunner scripts for a Scandinavian bank. One of them seeks to emulate a customer paying cash into their account. As you’d imagine, this is a high priority, high usage script so I’ve […]

Automated Testing Best Practices (Basic)

I wanted to prepare an article that specifies the very basic best practices for Automated Testing, whether its functional or non-functional. It seems to me that all the tools, whether open-source or commercial allow for these essential practices, presumably because this is the way we should all be doing it… some of us aren’t, you […]
