This post covers part four of my 2010 talk on testability. White box testability refers to specific programming practices and components that can improve or hinder testability.
Since Dykstra’s 1968 note “Go To Considered Harmful,” practices for producing clean, well-structured, readable, and maintainable software have been the subject of extensive discussion,…
Through Google Circles, I happened to see David Welton’s very interesting reflection on the Tcl programming language (posted in 2010):

About ten years ago, I chose to develop a commercial automated software testing tool with Tcl and Tk. This post explains that decision and its consequences.
Despite testing tools that tout “visual programming”…
I attended a great talk today about testing mobile applications, given by Lee Barnes of Utopia Solutions. It recounted the Rubik’s cube permutations that affect mobile app quality and reliability: multiple stacks, multiple handheld devices/form factors, constrained battery life, constrained memory/processor, variability of wireless connectivity, different behavior in dedicated…

Aren’t the dancing hamsters a stitch?
Not so funny if you have to test code whose stability or controllability makes you feel like you’re wearing the hula-hoop.
To reveal a bug, a test must:
Reach the buggy code
Trigger the bug
Propagate the incorrect result to an observable interface
Incorrect…
What makes a software system easier or harder to test?
The general aspects are controllability and observability.
This post covers part two of my 2010 talk on testability.
Controllability determines the work it takes to set up and run test cases and the extent to which individual functions and features of the system under test…
