HADAS: Analysing Quality Attributes of Software Configurations

Software Product Lines (SPLs) are highly configurable systems. Automatic analyses of SPLs rely on solvers to navigate complex dependencies among features and find legal solutions. Variability analysis tools are complex due to the diversity of products and domain-specific knowledge. On that, while there are experimental studies that analyse quality attributes, the knowledge is not easily accessible for developers, and its appliance is not trivial. Aiming to allow the industry to quality-explore SPL design spaces, we developed the HADAS assistant that: (1) models systems and collects quality attributes metrics in a cloud repository, and (2) reasons about it helping developers with quality attributes requirements.
