CUSTOMIZABLE TEST SET SELECTION USING CODE FLOW TREES

A method for identifying optimal tests includes defining functional coverage by a test suite based on a functional coverage model of a System Under Test (SUT). The test suite includes a plurality of tests. The functional coverage model includes a plurality of attributes, each attribute having a set of possible values. The functional coverage model defines possible combinations of values of the attributes as covered by the test suite. A subset of the possible combinations of values is determined. A subset of the plurality of tests is selected that is operative to cover the determined subset of the possible combinations of values. A plurality of trees is generated to represent the selected subset of tests. Complexity of the generated trees is analyzed based on user-specified criteria. An optimal tree is selected from the subset of the plurality of trees to achieve the objective of the test suite.
