Thomas Arts, co-founder and CTO of Quviq, has worked at Ericsson's computer Science Lab in the nineties. Together with Joe Armstrong, Simon Marlow and Phil Wadler, he tried to build a type system for Erlang. That being of little practical use, he later worked on verification tools for Erlang. After a short return to academia as professor at Chalmers, he is now fully devoted to amzing testing tools.
Quviq is the company that produced QuickCheck, a tool that automatically generates tests. The tool is written in Erlang, but can be used to test systems written in a variety of languages. Among other successes, it is heavily used within the telecom and automotive industry, for example for testing 5G base stations and AUTOSAR standard software.
