Abstract

A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to receive a system architecture model of a system and receive trigger coverage rules. Additionally, the programming instructions are operable to determine system integration test (SIT) coverage for each connection and interface of the system architecture model and select a set of use cases execution scenarios to satisfy the SIT coverage.
