This weekend on the flight from Seattle to Ireland I finally got to catch up on some reading. One of the books I grabbed off the shelf that I hadn’t gotten around to reading yet was Best Kept Secrets of Peer Code Review by Jason Cohen. The book is 160 [...]

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 just left Stockholm after spending a week there. That was my second visit to Stockholm and it is truly a remarkable city. I spoke at EuroStar which is the largest software testing conference in Europe, and had the opportunity to meet some old friends and colleagues as well as [...]

In the last post we decomposed the set of characters in the ANSI character set into valid and invalid class subsets for use in a base filename component on the Windows Xp operating system. The second part of the testing technique of equivalence class partitioning is to then use this [...]

Again, I am remiss in my postings…too many irons in the fire these days. Two weeks ago, I posted a challenge to decompose a set of character data (The ANSI Latin 1 Character Set) into valid and invalid equivalence class subsets in order to test the base filename parameter of [...]

Wow…where does the time go? I was remiss last week in posting, and it has been a month since I posted about equivalence class partitioning. So, let’s get back to it shall we?
Equivalence class partitioning (ECP) is a functional testing technique useful in either black box or white box test [...]

A few weeks ago a read an interesting post on SQA Forums about exploratory testing. It was interesting not because there was anything ‘new’ to learn about ‘exploratory’ testing; but because it offered a compelling counter-argument to ad hoc testing. It is also a good read because it differentiates exploratory [...]

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 been teaching formal testing techniques for several years at Microsoft and University of Washington Extension. Techniques are systematic procedures to help solve a complex problem. A technique does not find all types problems; techniques are generally very good at finding very specific classes of defects. But, the usefulness [...]

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 [...]
