This paper improves the breadth-¯rst search strategy in directed automated random testing (DART) to generate a fewer number of test data while gaining higher branch coverage, namely Static DART or SDART for short. In addition, the paper extends the test data compilation mechanism in DART, which currently only supports the projects written in C, to generate test data for C++ projects.

In this paper, we will prove a uniqueness theorem for meromorphic functions with finite growth indices on a complex disc sharing some small functions with different multiplicity values. Intersecting points between these mappings and small functions with multiplicities more than a certain number do not need to be counted.
