A '''software regression''' is a [[software bug]] that makes a feature stop functioning as intended after a certain event (for example, a system upgrade, [[Patch (computing)|system patching]] or a change to [[daylight saving time]]).<ref name=ibm-locating-bugs>{{cite

A properly designed [[test plan]] aims at preventing this possibility before releasing any software.<ref>{{cite book |last=Richardson |first=Jared |author2=Gwaltney, William Jr |title=Ship It!
