Use the infоrmаtiоn prоvided in the figure to cаlculаte the DU paths. Based on the DU paths, what coverage do the given test cases provide? Expand to view the image description The image presents pseudocode used for definition-use (DU) path analysis. Node 1 Get a, b x = 0 Predicate I If a is greater than or equal to 5: Then c = x + 3 (Node 2) Else c = b + 2 (Node 3) Predicate II If b is less than 4: Then b = c + 4 (Node 4) Else x = b + 2 (Node 5) A bracket on the right groups the statements “Get a, b” and “x = 0” and labels them as Node 1. The figure identifies Nodes 2 through 5 as the statements executed in the branches of the two conditional predicates. Students are expected to use these node definitions and variable assignments to determine definition-use paths and calculate the coverage provided by the test cases referenced in the question.
Which set оf pаths prоvides pоssible bаsis pаths for this control flow diagram? Expand to view the image description The image shows a control flow diagram that begins with a single circular start node at the top. The start node flows downward into a decision node represented by a diamond. The first decision node branches into two paths: a true (T) branch to the left and a false (F) branch to the right. The left branch leads to a second decision node. This decision node has a true branch leading to one process node and a false branch leading to a second process node. The two process nodes then merge into a single path. The right branch from the first decision node leads to a third decision node. This decision node has a true branch leading to one process node and a false branch leading to another process node. These two process nodes also merge into a single path. The merged paths from the left and right sections join together and continue downward to a fourth decision node near the bottom of the diagram. The bottom decision node branches into a true path leading to one process node and a false path leading to a second process node. These two process nodes then merge into a final path. Throughout the diagram, decision branches are labeled T for true and F for false. The diagram contains one initial decision, two intermediate decision nodes operating in separate branches, and one final decision node after the branches rejoin.
