Combinatorial Test Architecture Design Using Viewpoint Diagram

Software test has recently been a large-scale and complicated artifact, as is the software itself. It is necessary to reduce huge combinatorial test cases. This paper focuses on reduction of test parameters and combinations in test architectural design. First we will mention the test architecture design phase in TDLC: Test Development Life Cycle. Second we will introduce NGT: Notation for Generic Testing, which is a set of concepts or notation for design of software test architecture. This paper shows four examples of test architecture design patterns: Interaction-Viewpoint Conversion pattern, Interaction Cluster Partitioning Pattern, Interaction Demotion Pattern and Interaction Necessity Analysis.
