In L. Fejis et al. (2002) we proposed a general framework for defining a coverage measure based on a distance measure between different behaviors of a system under test and in N. Goga and F. Moldoveanu coverage formulas were given for the boundary bit value analyse test selection. On the current paper we instantiate these formulas for the data types of the ASN standard on which several standards are based, such as the TTCN-3 standard
