If DHH's main concern was practicality he wouldn't advocate UI & DB tests which are flaky, unreliable and expensive to maintain for any non-trivial application.

Code and system architecture absolutely should be bent to the needs of testing. Pretty and "clever" code is useless unless it does what it's supposed to do.

UI & DB tests absolutely have their place - I'm not disputing that at all, and I completely and whole-heartedly advocate their use - but they need to be used in conjunction with very fast, very reliable (and thus very useful) unit/integration tests that have been TDD'd.

Except DHH is not advocating 'pretty or "clever"', he's advocating readable and comprehensible code. I think it's unfortunate for you to put this trumped up straw man in the middle of an otherwise cogent argument.
