This past weekend I was working on a new test tool library for generating random email addresses; specifically the local address segment of an email address. I know, there are already a lot of email address generators available and this could be construed as reinventing the wheel. But I wanted to give my students in [...]

At a recent conference a speaker posed a problem in which a field accepted a string of characters with a maximum of 32,768 bytes, then asked the audience what values they would use for boundary testing. Immediately some of the attendees unleashed a flurry of silly wild ass guesses [...]

This morning I installed Vista SP1 onto my laptop. I was pretty excited about this release of Vista SP1 because it includes some pretty significant performance enhancements. But, as I was preparing to teach an internal course I came across a new boundary issue. I thought, how fitting this comes [...]

I previously discussed various types of defects exposed via application of the boundary value analysis testing technique including a repaint problem, a casting problem, and a wrapping problem. While the minimum and maximum physical linear boundaries of a parameter are often easy to identify, it is surprisingly more difficult to [...]

I have never been really good at math. Sure I understand basic formulas, but I rely on a calculator when I run out of fingers and toes. I am envious of people who can look at a hexadecimal or octal value and convert it to an integer value in their [...]

The traditional concept of boundary testing was established as a systematic procedure to more effectively and more efficiently identify a particular category of defects. Historically, boundary value analysis has focused on bounded physical (countable) linear input and/or output variables of independent parameters, and is especially useful in programming languages that [...]

If you like obscure bugs, then I think you’ll love this little gem!
USB flash drives are wonderful little gadgets, and I have several of them to store various files. Tonight I was using a flash drive to move some files around between machines when I noticed a slight problem. [...]

Over the past 3 days I have learned more about Mp3 file encoding and decoding than I have since the technology was introduced. I don’t spend time downloading files from the Internet to burn CD’s, I don’t own an iPod or Mp3 player, or a digital video recorder. So, prior [...]

My previous post refuting a conjecture by Pradeep Soundarajan suggesting there are no boundary values in software was a bit harshly worded, and to him and the readers I apologize. Occasionally I get a little overzealous. I am sure Pradeep is a great guy, and I must say his reply [...]

My friend and teammate Alan knows how passionate I get about certain things on occasion, so he threw me a bone the other day regarding a blog post on boundary testing, or should I say a rather a poor attempt to discredit boundary testing and boundary value analysis as a [...]
