FaMa Test Suite v1.2: ISA Technical Report ISA-10-TR-01

Abstract

A Feature Model (FM) is a compact representation of all the products of a software product line. Automated analysis of FMs is rapidly gaining importance: new operations of analysis have been proposed, new tools have been developed to support those operations and different logical paradigms and algorithms have been proposed to perform them. Implementing operations is a complex task that easily leads to errors in analysis solutions. In this context, the lack of specific testing mechanisms is becoming a major obstacle hindering the development of tools and affecting their quality and reliability. In this paper, we present FaMa Test Suite, a set of implementation–independent test cases to validate the functionality of FM analysis tools. This is an efficient and handy mechanism to assist in the development of tools, detecting faults and improving their quality. In order to show the effectiveness of our proposal, we evaluated the suite using mutation testing as well as real faults and tools. Our results are promising and directly applicable in the testing of analysis solutions. We intend this paper to be a first step toward the development of a widely accepted test suite to support functional testing in the community of automated analysis of feature models.
