Abstract: Interaction testing is an effective test suite generation technique and becoming a challenging problem. It is concerned with the interaction among several parameters of system under test (SUT) and can test the SUT effectively with smaller test suite. We described the interaction testing problem based on the interaction coverage criteria, explained four well-known combinatorial objects,classified several well-known interaction testing approaches by their characteris- tic and gave a brief interpretation of some classical approaches. We also gave a set of evaluation criteria and made a comparison among all the approaches. At last we gave a conclusion and discussed some issues to be further studied.
