Unformatted text preview: Software Testing, Quality Assurance and Maintenance Winter 2010 Lecture 6 January 15, 2010 Patrick Lam version 3 Prime Path Coverage versus Complete Path Coverage. n n 1 n 2 n 3 Prime paths: path( t 1 ) = path( t 2 ) = T 1 = { t 1 ,t 2 } satisfies both PPC and CPC. q q 1 q 3 q 4 q 2 Prime paths: path( t 3 ) = path( t 4 ) = T 1 = { t 3 ,t 4 } satisfies both PPC but not CPC. 1 Specifying versus meeting test requirements. Consider this graph. n n 1 n 2 n 3 The following simple (and loop-free) path is, in fact, prime: p = PPC includes this path as a test requirement. The test path meets the test requirement induced by p even though it is not prime. Note that a test path may satisfy the prime path test requirement even though it is not prime. Sidetrips and Detours Lets expand the notion of a tour. Recall that our definition of tour is strict: for path p to tour subpath p = [ n 1 ,n 2 ,n 3 ], p must contain exactly the sequence n 1 n 2 n 3...
