More testable service compositions by test metadata

Abstract

In previous work we proposed testable services as a solution to provide third-party testers with structural coverage information after a test session, yet without revealing their internal details. However, service testers, e.g., integrators that use testable services into their compositions, do not have enough information to improve their test set when they get a low coverage measure because they do not know which test requirements have not been covered. This paper proposes an approach in which testable services are provided along with test metadata that will help their testers to get a higher coverage. We show the approach on a case study of a real system that uses orchestrations and testable services.
