Improved Inter-class Integration Testing Sequence Algorithm Based on Extended ORD

The traditionally Object Relation Diagram (ORD) was extended to four types, inherit, aggregation, nest, and association in this paper. An improved inter-class integration testing sequence algorithm based on extended ORD was developed. Improved Kosaraj distinguish strong connected components was iteratively called to determine SCCs. The improved algorithm was compared with Tai and Traon. It had shown that the improved algorithm need less testing station and higher efficiency. The primary experiments and theorized analysis proved the method is approving and promising.
