done extensive fuzzing work; It carried out a fuzzing audit in 2020 which added coverage to complex text processing routines. Vitess is integrated into OSS-Fuzz which allows the fuzzers to run continuously follows with VTAdmin as well as the remaining code base. Vitessʼs fuzzing suite is extensive, targets complex parts of the code base and runs continuously on OSS-Fuzz which are important elements of a solid
