Analysis of MC/DC Coverage Percentage and Cyclometic Complexity for structured C Programs

Now a days, testing activity consumes about 60% of software development resources, so any concept aiming at reducing Software Testing costs are likely to decrease the whole development costs. Proposed by NASA in 1994, the MC/DC criteria is a testing strategy required, among other practices, by the RTCA DO-178B. MC/DC is a white box testing criteria targeting at proving evidence that all clauses involved in a predicate can influence the predicate value in the required way. We automated the concept to identify predicates in structured C-Program using predicate identifier and Cyclometic Complexity Calculator. We automated the generation of number of test cases required to satisfy the MC/DC criteria using CREST Tool and evaluating MC/DC coverage percentage using coverage analyser.
