A Human-centred Framework for Combinatorial Test Design

This paper presents AHR, a formal framework for combinatorial test design that is Agile, Human-centred and 
 
Refinement-oriented. The framework (i) allows us to reuse test plans developed for an abstract level at more 
 
concrete levels; (ii) has human-centric interface providing queries and alerts whenever the specified test plan 
 
is incomplete or invalid; (iii) involves analysis of the testing constraints within combinatorial testing.
