“…It is widely agreed that new test applications can be fast developed through the reuse and reorganization of existing design solutions [2]. Nowadays, different from common languages which fix the test logic in the code, a lot of test description languages have been developed, such as ATML [3] [4], CTL [5], TTCN-3 [6] [7] and so on.…”

The CTCS Hardware-In-the-Loop Simulation (HILS) system is currently under developing and needs to be tested thoroughly. According to the requirements of concurrency and configurability, a test process model based contract-checking test method (CCTM) is proposed to execute the test verdict on-line. By analyzing several test applications, the test process could be abstracted as a test event chain. And every test event has its own preconditions and consequences, which are considered as a formal contract. Checking a contract, we can easily monitor the test stimuli, observation and verdict. Then, the function modules and the crucial techniques in applying CCTM to distributed railway test system are described. The applications in CCTM show that the proposed test method satisfies the test requirements of the CTCS HILS system.

“…But functional model is not a better representation for parallel test system because of its low level of abstraction. Furthermore, functional models tend to be oversimplified because of neglecting some important aspects of test systems, such as the coupling between the instrument and the UUT [3]. Object-Oriented method first occurred in the development of a simulation language-SIMULA 67 forty years ago [5].…”

Compared to traditional sequence test, parallel test, which means multiple units-under-test (UUTs) can undergo testing simultaneously, can improve test throughput by increasing the number of test tasks in a period of given time, improve instrument usage by reducing idle time of CPU and instrument, save test cost by sharing expensive instrument and device. Built on general automatic test system, parallel test system belongs to complex test system. Associated with the traditional way, test and measurement are usually modeled with functional representations. But functional model is not a better representation for parallel test system because of its low level of abstraction. By raising the level of abstraction from the function-level to the object-level, objectoriented approaches focus on the real-world aspects of a system and provide a better model of parallel test system. The Unified Modeling Language, or UML, is a third-generation object-oriented modeling language. And Rational Unified Process (RUP), which is developed and maintained by Rational Software Corporation, is on the base of UML, and is a sort of modeling approach together with UML. In this paper, an object-oriented model of parallel test system will be built according to Rational Unified Process (RUP).Accompanied RUP, a serial standardization analysis and design documents, which describe parallel test system in UML, will be produced. These documents can be contributed to engineering realization of parallel test system.
