Scheduled releases and the importance of Regression Testing

Michael Bolton first highlighted the difference between testing and checking. The output of checks are binary results (true/false, on/off, black/white). Checks can be executed by humans or automatically by machines. The output of testing is questions, facts and information. Tests can only be executed by humans.

For the purposes of this article, I’m going to focus on the problem solving/creativity side of things, not the artistic side. The side we all possess but most ignore. Sir Ken Robinson’s explains why and where we lost our creative way in his Ted Talk about creativity.
