原始语种摘要: SUMMARY(#br)This paper addresses integration testing of data‐centric and event‐based dynamic service compositions. The compositions under test define abstract services that are replaced by concrete candidate services at runtime. Testing all possible instantiations of a composition leads to combinatorial explosion and is often infeasible. We consider data dependencies between services as potential points of failure and introduce the k‐node data flow test coverage metric, which helps to significantly reduce the number of test combinations. We formulate a combinatorial optimization problem for generating minimal sets of test cases. On the basis of this formalization, we present a mapping to the model of FoCuS, a coverage analysis tool. FoCuS efficiently computes near‐optimal solutions, which...
