Basis Testing Overview

Basis Testing is a White Box test case technique employing control flow graph representations of program module logic. Control flow graphs are network diagrams graphically depicting the logical pathways through a module. Test cases are created based on a set of independent paths enumerated from the graph. Thomas J. McCabe developed this method, formally known as Structured Testing and informally called basis testing. McCabe's approach will be discussed as a White Box test case development strategy and not as a testing methodology. For a comprehensive discussion of McCabe's methodology, see his original work (11,12).

The major advantage of McCabe's approach is that it incorporates the Cyclomatic Number ...
