control flow testing. Consider the following code $1$ int binsearch $($int X $,$ int V $[],$ int n $)2\{3$ int low $,$ high $,$ mid $,$ i ; $4$ low $=0$; $5$ high $=$ n $-1$; $67$ for $($ i $=0$; i $<$ high ; i $++)8\{9$ if$($ V$[$ i $]>$ V $[$ i $+1])10$ return $-2$; $11\}1213$ while $($ low $<=$ high $)14\{15$ mid $=($ low $+$ high $)/2$; $16$ if $($ X $<$ V $[$ mid $])17$ high $=$ mid $-1$; $18$ else $19$ if $($ X $>$ V $[$ mid $])20$ low $=$ mid $+1$; $21$ else $22$ return mid ; $23\}24$ return $-1$; $25\}$ This code takes as input a sorted array V of size n$,$ and an integer X$,$ if X exists in the array it will return the index of X$,$ else it will return $-1.1.$ Draw a CFG for binsearch$().2.$ From the CFG$,$ identify a set of entry$$exit paths to satisfy the complete statement coverage criterion. $3.$ Identify additional paths, if necessary, to satisfy the complete branch coverage criterion. $4.$ For each path identified above, derive their path predicate expressions. $5.$ Solve the path predicate expressions to generate test input and compute the corresponding expected outcomes. $6.$ Are all the selected paths feasible? If not, select and show that a path is infeasible, if it exists. $7.$ Can you introduce two faults in the routine so that these go undetected by your test cases designed for complete branch coverage? $8.$ Suggest a general way to detect the kinds of faults introduced in the previous step.
