Thoughts on Professionalism

As a young lad growing up on the shores of the Chesapeake Bay I would often spend part of my summer vacation from grade school helping my grandfather work the crab pots on the north shore. Now, don't think "Dangerous Catch," crabbing in the Chesapeake

Test Automation: Simple Automated Test Case Templates

Templates can be useful tools to help increase individual efficiency and team consistency. Yet, I am sometimes quite surprised that some organizations lack standard templates for such daily routines such as bug reporting, status reporting, and even test

Test Automation: Programmatic Platform Profiling

Occasionally, the execution or outcome of a test depends on the operating system version on which the test is executed. Platform profiling is important because subtle differences in operating system platforms can affect how certain tasks are carried out,

Do testers do code reviews?

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

UTF What?

Years ago life was pretty simple with regard to data input. Most computer programs were limited to ASCII characters and a set of character glyphs mapped into the code points between 0x80 and 0xFF (high or extended ASCII) depending on the language. The

Automation Foibles Unveiled: Coding Guidelines Part 1 - Basic Layout

It has been awhile since I have written about test automation, so I thought I would start the new year off with a post about test automation. More specifically, I wanted to start talking about coding guidelines. Just as many development teams have adopted

Exploratory testing vs. Scripted testing; Is it really only either or?

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

Equivalence Class Partitioning Part 3 - The tests

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

Equivalence class partitioning - Part 2: Character/String data decomposition

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

Equivalence class partitioning - Part 1

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

Boundary testing - hidden loops and the Deja Vu Heuristic

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

Equivalence class partitioning

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

Boundary testing and wrapping; or 1,073,741,824 * 1,073,741,824 = 0

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 heads

Casting types and boundary testing

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)

Why we automate

I never really understood why so many people external to Microsoft seem to be against the Microsoft strategy to increase the amount of automation we rely on to test our products. Test automation has become sine qua non at Microsoft for many valuable reasons.
