I read the paper titled PCT, in which it is mentioned that PCT is stronger than Multiple Condition Coverage (MCC), but it has never compared PCT with MC/DC in entire paper. So, as we know MCC is stronger than MC/DC, hence should we assume PCT is stronger than MC/DC too? Also, authors have mentioned that PCT is incomparable to path coverage, but we know that we can have a comparison study of path coverage and MC/DC. Please also share, whether PCT suffers from Combinatorial Explosion issue. So, please come and share your views and experience on this question.
