Systematic and holistic approaches for handling variability throughout and beyond engineering are required in many industrial domains. Products for these domains are often safety-critical and require significant effort in validation and verification, particular testing. This talks will introduce how pure::variants, our Variant Management product, assists/supports testing of Product Lines. We will also look at ideas how to exploit variability information beyond what is possible in todays commercial solutions for Product Line Engineering. Despite being a talk given virtually and possible technical challenges, my intention is to interact with the scientific experts in the field ( aka you) during this talk.
