Gold Master Testing - Code Climate Blog

Gold master testing refers to capturing the result of a process, and then comparing future runs against the saved “gold master” (or known good) version to discover unexpected changes. For us, that means running full Code Climate analyses of a number of open source repos, and validating every aspect of the result. We only started doing this last week, but it’s already caught some hard-to-detect bugs that we otherwise may not have discovered until code hit production.

A great idea, but something I definitely see as more beneficial to larger projects than smaller ones.  Obviously it makes a ton of sense for Code Climate for the reasons they delineate.
