Equivalence Class Partitioning: Is It Real Or Is It a Figment In Our Imagination?

Originally Published Tuesday, September 30, 2008
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 [...]

Equivalence Class Partitioning Part 3 – The Tests

Originally Published Thursday, November 29, 2007
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 [...]

Equivalence Class Partitioning – Part 2: Character/String Data Decomposition

Originally Published Thursday, November 15, 2007
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 [...]

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 in either black box or white box test [...]

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 [...]
