Debating test distribution
Two guys from ThoughtWorks (one dev and one test fellow) share their take on testing and test distribution (unit vs. integration vs. acceptance). The dev guy thinks that ~70% unit tests, ~20% integration tests and ~10% acceptance tests form a reasonable test pyramid.

The answer, surprisingly, is not that they have more will or discipline than you do. The counterintuitive secret to getting things done is to make them more automatic, so they require less energy.
It turns out we each have one reservoir of will and discipline, and it gets progressively depleted by any act of conscious self-regulation. In other words, if you spend energy trying to resist a fragrant chocolate chip cookie, you’ll have less energy left over to solve a difficult problem. Will and discipline decline inexorably as the day wears on.
