Re: Ensuring that all code is tested
When my father was learning to drive a passenger bus many many years ago, the actual driving lessons were organized in groups. at the beginning of the first drive the instructor would ask who wanted to drive first. After someone volunteered, he'd order the rest of the group to stand in the aisle. With their hands in their pockets.
The problem today is that there is no single driver anymore so there is no way to get the required level of peer pressure to work.
