Summary
A tool supports SQLFuzz and General Fuzz by mutation, then detects suspicious code block leading to bugs in fuzz automatically by monitoring code execution path of application.
Motivation
There is a lot of uncertainty in Chaos and fuzz test of complicated software like tidb.
Developers often costs a few of weeks to localize the root cause.
this tool may help on this.
