Rating of software trustworthiness via scoring of system testing results

Abstract

It is important to have a form of software trustworthiness rating serving as early health indicator on the capability of the software before it is released to end-users and customers. Although various software certification schemes are available in the market, there is limited information on how far results from system testing are exploited and used to rate the trustworthiness of the software under test. Thus, the proposed software trustworthiness rating strategy uses the scoring upon the completion of system testing execution. The strategy covers rating of software that has undergone system testing completely or partially. It is based on multiple levels calculation toward coming out with final rating: test strategies imposed, completeness of system test execution, test iterations, test case priority and test case result for each iteration. As a result, the multilevel scores calculation successfully derives meaningful trustworthiness rating for the software under test, whether it is a complete rating or partial rating.
