Error Injection
Finally, the ROC team is working on general mechanisms for fault injection. Fault injection has been a common method for verifying hardware reliability and testability but is only now being brought to software. A group of Berkeley graduate students has developed the Fig (for fault injection in glibc) to test the capability of programs to correctly cope with unexpected errors in the standard C library.
Error injection permits computer programmers to test their repair mechanisms, which is difficult to do. Fig would allow operators to try their hands at diagnosing and repairing failures, perhaps on a small experimental system if not on the real thing.
