UML activity diagram is suitable for modeling parallel and concurrent flows in an actual system. It is also significant for software testing. The subactivity state in activity diagram divides the activity diagram into two kinds: the atomic activity diagram and compound activity diagram, who constructs the hierarchy of the whole activity diagram. Dealing with the compound activity diagram is a key issue during test case generation. This paper proposes a method for generating test case from subactivity diagram to compound activity diagram hierarchically and introduces the idea of this method by taking the thought of functional decomposition, bottom-up integration testing strategy and round-robin strategy. The experimental result shows that the proposed approach can generate less test cases than the method taking complete combination strategy and have a good coverage as well.
