Behavior-Driven Development of Software Product Lines

Abstract

Software product lines (SPLs) develop families of similar software products, which share a standard set of features, and they build in variety via optional features. That means customers can select features according to their needs and come up with a product configuration. Then the SPL is expected automatically to generate and test the software product for the chosen configuration. There are various SPL solutions for the automatic generation of software products, but those SPLs lack automatic testing of the generated product. To overcome this shortcoming, the SPL should automatically compose a test suite according to the selected features, automatically execute the test suite on the product, and automatically generate a test report delivered to the customer with the product. This paper proposes such an approach through behavior driven development. The proposed method is evaluated with a smart home SPL. © 2021 IEEE.
