Orthogonal software testing: Taguchi methods in software unit and subsystem testing

摘要: Suggests that, in order to detect and correct software defects as early possible, identifying generating more defect‐sensitive test cases for unit subsystem testing is one solution. Proposes an orthogonal approach based on the quality optimization techniques, Taguchi methods. This treats input parameters of a or design factors arrays, stratifies parameter domains into equivalent classes form levels factors. Describes how are generated statistically each trial factorial experiments. The adequacy can be validated by examining coverage metrics. results case executions analysed find sensibility detecting defects, generate effective further testing, help locate stage testing.
