I was recently listening to a JavaScript Jabber podcast featuring Dan Abramov, where he stated that he got into software development because at school he was taught PowerPoint: he loved making animations, and one day discovered the macros that powered those animations. These macros were actually scripts: by changing values within them, Dan could programatically alter the animations.

This reminded me of my own route into the software industry: though WordBASIC (most of you under 40 probably won’t remember WordBASIC: it’s what Word macros were written in before we had Visual Basic for Applications).

This seems to me to misunderstand the purpose of unit testing. I can see how this misunderstanding comes about: there is a general acceptance that tests are good, and that a high level of test coverage is good, therefore increasing coverage must be a worthwhile thing. Right?
