Tiny TTCN-Inspired Testing Tools for Experimenting with Hybrid IoT Systems

This work presents the design of a lightweight, low-end, virtually zero-cost on-line passive testing technology (Tiny TTCN-inspired Testing Tool) that is complementary to other, well established testing frameworks. A tester is built around an Arduino-class microcontroller and is programmed in a test language that re-creates the basic semantics and look-and-feel of the standardized test language TTCN-3 (Testing and Test Control Notation). It is intended for rapid prototyping and as a one-off development platform for the validation of IoT-class distributed systems involving humans-in-the-loop, especially for long-term unobtrusive supervision of in-the-wild behaviour change experiments in an instrumented home/work facility. To justify feasibility claims, selected implementation details are also reported.
