Friday, August 27, 2010

Well, I am back from a sailing excursion to the San Juan Islands. I wanted to go to the Gulf Islands, but considering an unexpected ordeal with a kidney stone just before taking off on the trip I decided it might be better to be a bit closer…just in case. The weather was great, [...]

Besides lots of practice perfecting the techniques a big part of precision shooting depends on the ammunition and studying the ballistic patterns of various loads. All precision shooters custom load their ammunition and it is not as simple as simply reading a [...]

Tonight on my way to teach a test automation course at the University of Washington I had some free time to catch up on my reading. My manager asked me if I had read this month’s copy of one of the several testing magazines we get and I replied that I had downloaded it but [...]

In the book How We Test Software at Microsoft I discuss structural testing techniques. Structural testing techniques are systematic procedures designed to analyze and evaluate control flow through a program. These are classic white box test design techniques, although my friend and respected colleague Alan Richardson states in his [...]

The Code Coverage Metric is Inversely Proportional to the Criticality of the Information It Provides.

Friday, November 13, 2009

One of the best aspects of my current role is the opportunity to interact with so many talented, highly skilled, and extremely intelligent testers at Microsoft and other companies around the world. Last week I was teaching a new group of SDETs at Microsoft, and during our discussion of code coverage (the metric) and code [...]
