Measuring Coverage Percentage for C Programs using Code Slicer and CREST Tool

Augmented test suite generation is a technique to minimise test effort and duration. Modified condition and decision coverage (MC/DC) is a white box software testing criteria targeting to prove all the conditions involved in a predicate which can influence the predicate value in an efficient way. The coverage analysis is a structural testing method, which helps to remove gaps in a test suite and determines when to stop testing. In this paper, we propose an augmented method to generate a test suite that helps in measuring coverage percentage of a program. We propose a technique which consists of mainly three modules. The crest module is a program slicer, who accepts a program written in C language and uses some slicing criteria results an executable sliced program. The second module is the CREST tool (CONCOLIC tester) which accepts the executable C sliced program as an input. The CREST tool drives to generate the test suite. The third module is Coverage Analyser (CA) to compute the coverage percentage. Our technique helps to achieve the coverage percentage with time taken to execute the program.
