Query: Continuously Testing Distributed IoT Systems: An Overview of the State
  of the Art   The continuous testing of small changes to systems has proven to be useful
and is widely adopted in the development of software systems. For this,
software is tested in environments that are as close as possible to the
production environments.
  When testing IoT systems, this approach is met with unique challenges that
stem from the typically large scale of the deployments, heterogeneity of nodes,
challenging network characteristics, and tight integration with the environment
among others. IoT test environments present a possible solution to these
challenges by emulating the nodes, networks, and possibly domain environments
in which IoT applications can be executed.
  This paper gives an overview of the state of the art in IoT testing. We
derive desirable characteristics of IoT test environments, compare 18 tools
that can be used in this respect, and give a research outlook of future trends
in this area.
