Combinatorial interaction testing (CIT) approaches systematically sample a given configuration space and select a set of configurations, in which each valid t-way option setting combination appears at least once. A battery of test cases are then executed in the selected configurations. Existing CIT approaches, however, do not provide a systematic way of handling test-specific inter-option const...

We believe that we can exploit the benefits of combinatorial interaction testing (CIT) on many “non-traditional” combinatorial spaces using many “non-traditional” coverage criteria. However, this requires truly flexible CIT approaches. To this end, we introduce Unified Combinatorial Interaction Testing (U-CIT), which enables practitioners to define their own combinatorial spaces and coverage cr...
