Firstly, system model depicted by TSIOA is transformed into an USTGSS (untimed stable label transition graph of symbolic state) which does not contain abstract time delay transitions. Then, the testing methods based on LTS are used to the generate transition sequences from USTGSS according to structural coverage criteria. Finally, a process of constructing and executing the test cases is given, in which object functions of time delay variables are imported, and time delay variables used in the transition sequences are solved dynamically by linear programming techniques.
