Testing & Covering Graphs (7.2) We use graphs in testing as follows:-Develop a model of the software as a graph-Require tests to visit or tour specific sets of nodes, edges, or subpaths Test requirements (TR): Describe properties of test paths Test …

To test the inheritance hierarchy graph, we need to instantiate objects for the classes.

Example: a path may demand that a loop be executed zero time, where the program always executed the loop at least once. This problem is based on the semantics of the software artifact that the graph represents.

Mar 11, 2022 · A graph matrix is a data structure that can assist in developing a tool for automation of path testing. Properties of graph matrices are fundamental for developing a test tool and hence graph matrices are very useful in understanding software testing concepts and theory. What is a Graph Matrix ?

An inheritance graph model is a graph where the vertices are Java reference types (that is, classes, interfaces, enums, annotations) identified by their fully-qualified name. Whenever one type C has an inheritance relationship with another type P , there is a directed edge C->P .

Directed graphs form the foundation for many coverage criteria. Given an artifact under test, the idea is to obtain a graph abstraction of that artifact. For example, the most common graph abstraction for source code maps code to a control flow graph.
