A couple of years back I wrote a short piece titled
and Continue – Valuable Tool, or Sloppy Vice?“
I pondered whether some development tools and practices
– such as test-driven development (TDD) and
the reduced cost of errors (in both time and
personal reputation) – were actually making us worse
developers, paradoxically decreasing productivity and the
suitability and correctness of solutions.
That entry was motivated by the outpouring of demands by my
peers that a particular tool continue to feature edit-and-continue
functionality: what I thought would be an infrequently used frill
turned out to be something that many depended upon daily,
correcting their flawed code at runtime as a regular part of their
Today I came across DevGrind’s

from Sodoku Solver” – where he links to a gent who
implemented a thoughtful, sober design carefully, and another who
pursued a TDD-approach, building his test harness, and then, it
appears, flailing about madly in the hopes that some random
keypresses will generate a solution that passes the test.
To demonstrate the value of TDD.
