Mozbase is a set of easy-to-use Python packages forming a supplemental standard library for Mozilla. It provides consistency and reduces redundancy in automation and other system-level software. All of Mozilla's test harnesses use mozbase to some degree, including Talos, mochitest, reftest, Autophone, and Eideticker.
