Estimating Residual Faults from Code Coverage

Bishop, P. G. (2002). Estimating Residual Faults from Code Coverage. Paper presented at the SAFECOMP 2002, 10 - 13 Sept 2002, Catania, Italy.


Many reliability prediction techniques require an estimate for the number of residual faults. In this paper, a new theory is developed for using test coverage to estimate the number of residual faults. This theory is applied to a specific example with known faults and the results agree well with the theory. The theory is used to justify the use of linear extrapolation to estimate residual faults. It is also shown that it is important to establish the amount of unreachable code in order to make a realistic residual fault estimate.
