Bugs related to the interaction of more parameters decrease with the number of parameters; in other words, finding these rare bugs will require much more tests to be performed, leading to more time/costs. However, those rare t-way interaction faults can also be critical and address by proper testing techniques.

Recommended Option: Combinatorial Testing considering 2-way (pairwise) and t-way interaction of parameters

Given the empirical data mentioned earlier, adopting combinatorial testing is an approach that provides great results in terms of fault detection/defect slippage prevention with manageable test suite size.
