  • Blog Post: "Good enough" is not good enough!

    This week I came across a discussion [regarding test design] in which a tester wrote, "… the main goal is having something that is 'good enough' ." Every time I hear a tester utter the phrase " good enough " my head wants to explode! Wrapping duct tape around a splint on the broken handle on my hoe...
  • Blog Post: Equivalence class partitioning: is it real or is it a figment in our imagination?

    Last week I attended the Software Testing and Performance conference in Boston. I presented a workshop on Systematic Testing Techniques, as well as a talk on random test data generation, and combinatorial analysis. One way I continue to learn about our profession and increase my own knowledge is by going...
  • Blog Post: Think before re-inventing the wheel

    There are rare occasions when an exceptionally bright and innovative person comes along and actually builds a better 'mousetrap.' My friend Ken Smith is one such person. Ken is the inventor of SmartPlug . Anyone with a boat that connects to shore power has experienced the aggravation of lining up the...
  • Blog Post: Certification Wars

    I started diving in the late 70's, and in1985 I became a PADI certified open water scuba instructor. In those days, scuba instruction involved a lot of classroom time discussing various concepts that impacted human physiology such as Boyle's Law, Dalton's Law, Haldane's Principle, and also immediate...
  • Blog Post: Contextual blindness: or How to take things completely out of context

    Many testers are familiar with the concept of inattentional blindness (or at least should be in my opinion). Basically inattentional blindness occurs when we are so visually focused on a task or object that we completely fail to see something out of the ordinary. But, I am going to introduce my own...
  • Blog Post: How Professional Testers Think: Why Microsoft primarily hires testers with a Computer Science, Math or Engineering background?

    The easiest thing to criticize is that which one does not fully comprehend. There has been a lot of discussion lately about Jerome Groopman's book How Doctor's Think and a correlation between doctors in the medical profession and software testers. The book is an excellent read, and provides readers...
  • Blog Post: Blindly buying into rumor and innuendo: or how to lose stock in your credibility

    It never ceases to amaze me that every time we see a calamity involving software the immediate reaction of the sensationalist media types and other people who are generally misinformed is to blame inadequate testing. Recently, it seems that Joel Spolsky not only fell victim to rumors and misinformation...
  • Blog Post: Exploratory Testing versus Ad Hoc Testing

    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...
  • Blog Post: Tools for testing smarter; not harder!

    Today I was reminded about the fictional account of an aircraft carrier and a lighthouse in which the carrier and her escorts were navigating in dense fog and a target appeared on the radar that appeared to be on a collision course with the carrier group. The captain signaled to the target advising it...
  • Blog Post: A little bit about me...

    Well, I guess I hit a nerve that caused James Bach to put me square in his crosshairs. James' dislike for me is clearly seen in a reply on his blog , and unfortunately personal bias often distorts the facts. This is a shame because I think to some extent James and I agree on the need for more, and better...
  • Blog Post: Rambling...

    I am feeling rather facetious tonight, so if you don't want to bear with pointless diatribe, then don't proceed. OK....if you've made it this far, then let's start. The other day I happened to be watching a Google video featuring Jon Bach explaining exploratory testing yet again. <TANGENT> I...
