perhaps "background confidence checks" ? If resultant system is "enhanced", would the project still encompass such checks ?
Won't it often be that there is a "contract amendment" to add new functionality ? Won't it often be the case that proper re-testing will be much more expensive than what is charged for in the "contract amendment". So proper re-testing does not take place. So although the original contract envisioned such capabilities as "overnight regression testing" and "automated testing", these capabilities are not present in the system as amended and delivered ?
